3.2.- Storage Instructions
These instructions are for storage of less than
12 months from date of despatch. In the case of
storage for longer periods please request
manufacturer's long-term storage instructions.
Before storaoe;
-This equipment must be stored in a dry enclosure,
rotected from impacts, sunlight, dust and flooding. WARNING 3- Pumps should not be stacked even when the'
typs of packing allows it.
I - Both close coupled and bearing stool pumps A
must be stored on the original factory supplied
pallets or in any other way that is stable.
-The pump and its auxiliary conduits must be empty
of pumped liquid.
- It is advisable to cover unpainted areas with a
protective film (such as vaseline).
-Apply oil or liquid rust-proof to the wear ring faces
via the suction flange to avoid them seizing up.
- Pumps supplied on a movable base plate
(trolley etc) should be secured by use of the
brakes or
locking mechanism fined
- The electric motor and the cables must be
disconnected and the terminal box
lid closed. - Electrical panels must be disconnected and placed
vertically.
After storaoe:
- Remove the temporary protection (part 3.1) and
check the state of all components visually.
- If the pump has been stored and out of use for a
prolonged period (more than
6 months) it is neces-
sary to:
Change the gland packing
(i model uses it).
Renew the bearing lubricant.
Check the state of the couplings.
Check that the installation is level.
Check all the auxiliary connections.
- Following a short storage period it will suffice to turn
the pump shaft manually to free up the impeller
mechanism.
- For the motor and all the other related elements.
carry out the steps described in the 'after storage'
section of the respective manuals.

llowthe steps given in 'startingthe pump' section.
If the equipment is going to be left unused for a
long period
and there is a
possiblw of freezing il
shouldbe drained mmpletely to avoid any risk oi
damage being caused by freezing of the liquid
inside.
3.3.- Transport and Handling
The,transport and handling of this equipment must be
csrned out using means capable of supporting the
load. The weight is usually indicated on the invoice or
on the name plate. If it is not and there is a doubt
concerning the suitability of the handling equipment,
please contact the manufacturer, 'Bombas ITUR'.
In order to ease handling, eye-bolts are fitted where
necessary to the base plate upon which the pump
equipment stands. However, the whole unit should
never be lifted by the eyebolts intended for lifting one ol
its parts, such as the motor or pump. Do not use the
necks and flanges on the pump and plpework nor the
mgs or futings to lift the pump unit.
2 WARNIN If the pump is to be lifted uslng e sling thls must
pass under the body of the pump and motor in the
case ofunitsmountedon a movable base-plateanc
under the houslng in the case of vertical pumps.

- EQUIPMENT DESCRIPTION.
RC pumps, RCVpumps (vertical version of RC) and RCA
pumps are gear displacement pumps with axial in-line
suction and delivery. RC-OOand RC-01 sizes aresupplied
in close coupled configuration and are not available in
vertical versions.
CLOSE COUPLED
RC (Bare
shaR)
RCV (VERTICAL)
RCA series pumps include an internal thermal isolation
chamber.
This manual outlines installation In a fixed location.
According to the size and type of pump ordered a
number of pieces may be deliberately omitted such
that certain parts of this manual will not be applicable
to all pumps. These parts may be, for example:
- Retainers, mechanical seal or packing gland.
- Roller bearing or friction bearing.
-Type of motor
(7 The pump only has one or other of these systems
/1 These pumps are only suitable for clean, solid-free
liquids.
The sound pressure of these pumps is less than
96
dB(A) at any moment of operation (given that the flow
is above the minimum required for each model). The
sound power is less than 110 dB(A).
4.1. Shafl seal
Models RC-00 and RC-01 use retainers and all other
models use mechanical seals or packing-gland.
4.2. Surge or by-pass valve.
All pumps in this family have an internal surge valve
which recirculates the liquid if the delivery pressure
exceeds rated pressure. This protects the pump
anc
installation from excess pressure.
As a rule of thumb this valve should be set to
2
kgtcm'
above the pressure stated in the order and should nu
be changed by the user. The valve is always locater:
next to the pump delivery flange.
A Unauthorised changes to this valve run the risk o
excess pressure (which may damage pipework o,
pump) andlor destruction of the motor on acwun
of the excess load.
A The sefefy valve shouldnot be usedto regulate thc
flow or the discharge pressure as this may caust
dangerous heating of the liquid.

11. - INSTALLATION
The design of the pipework, anchoring and
other parts of the installation is not the
res~onsibilitv of the manufacturer. rrUR offers
information&dsuggestionsby way ofguidelines
only and cannot assume responsibility for the
design, assembly and running of an installation.
We recommendthe customerwnsulta specialist
in mountings, pipework, wells etc. to complement
the information supplied by us and thereby
ensure correct running.
5.1.- Mounting
The unit can be mountedon a large foundation.
This foundation mustprovide a flat, level surface.
The unit is to be attached to this platform by
anchoring bolts designed to avoid vibration caused
by operation of the pump.
5.1
.I.- Anchoring bolts
'Bombas ITUR' can supply the anchoring bolts.
They are fitted as follows:
Mode of use:
- Place the equipment over its base.
- Drill holes in the base in the points corresponding
to the anchoring points into which to fn them.
- Level up the unit.
- Once the equipment is located on its foundation
and the boltsarefid into the holes, pourcement
(do not use quick setting cement) into the holes
and allow
48 hours for it to dry.
- Level up again and tighten the bolts.
5.1.2.- Levelling up
A conventional spirit-level may be used to level up the
unit. The unit must be levelled UD both lenuthwavs and -
crossways.
If
it is necessary to level the base plate by using
wedges small pieces of cut sheet metal should be
used. Bond them with
askin of cement to prevent them
from deforming when the bolts are tightened.
Once levelling has been completed it is wise to fn a
lock-nutto each of the boltssothatthey do not become
loose during operation.
Equipment suppliedmounted on a movable base
plate must besecured by use of the brakes or the
fixing mechanism fitted prior to start
up.
In the standard version all RC, RCV and RCA pumps
include a flexible coupling except
RC-00 and RC-01
sizes (closecoupled) which have a rigid, coupling.
Equipment supplled in the form of a complete
motor-pump unit will already have been aligned in
the factoty. However, owing to movements that
may be caused during transpoltation and mount-
ing tt must be realigned before use.
MI1
I I'
The unit must always be aligned once all parts
are assembled and it is ready for start up.
The correct alignment of the standard ITUR drive
coupling consist of ensuring that it is both parallel
and concentric by chocking up the motor as neces-
sary.
- Measure the distance between thecoupling endsin
four posm'ons 90' apart between the faces of the
coupling using a micrometer. All four measurements
should be the same (-3mm). The male and female
coupling should never be butted up together.
-Take the following measurements:
The maximum recommended tolerances for ITUR
couplings, with and without a spacer between the
motorand the pump, am a~en inthefollowina table
.
.. - -
(all measurements in mm):
NB Refer to the manual provided if other types ol
drive couplings are used.
5.2.2.-
Rigid Coupling
All units are factory aligned and this alignment is
not lost unless the unit is dismantled. If this is the
case the following steps should be taken once re-
assembled:
-Check that all the flange supporting surfaces
betweenthemotorand pumparecleanandsmooth.
- Insert the motor shafl into the pump without
forcing
it so as to avoid damage to the bearings. - Checkalignment between both shafts turning the
assembly by hand and measure possible
misalignment with a comparator.
5.3.- Plpework
unlons
Strain on the pump collar can cause misalignment ol
the flanges. To reduce strain the flanges must be
parallel and concentric. The bolts or studs used to fix
the flanges must pass freely through the holes drilled
in them. Do notforgetto placeasealorgasket between
rts of the joint.
Do notuse thepumpitselfasastrucfuralmembei
of the installafion~ The inlet and outlet pipe:
should not place anv strain on the pump necks
above the 'maxlmum Ilmits. Use indebendenl
braces to hold the welght and the strein of the
plpework. Pay attention to the direction of flow
lnbicated In the diagrams.

12. Diameters of pipes, valves and fittings must be calcu-
lated on the basis of friction losses foreseen in the
installation design and such that liquid velocity matches
its viscosity.
JN It is advisableto use acoarsefilter
in the inlet pipe to avoid the pump drawing in lumps of
dirt and debris larger than the permitted size. Elbows
andsharp cuwes in the pipeworkshould be avoided, as
should fittings that
produceabruptnarrowingorwidening
of the pipe (such as cones, valves etc)
THE OUTLET
PIPE should generally be of a greater
diameter than the mouth of the pump. A gate-valve
should also be fitted to regulate the flow and avoid
overloading the motor. This valve can also be used to
isolate the pump for maintenance.
I if hoses are used in either the inlet or outlet they A
must be
able to withstand pump pressures and
adequately restrained to prevent their movemenl
causing damage or injury.
IF OPERATED AS A FLOODED PUMP the inlet line
must be airiight and normally of adiameter greaterthan
that of the mouth of the pump. The diffuser cone may be
either eccentric or concentric. Fit a gate valve for
isolation during maintenance.
theinlet linemust becompletely airtight and rise upward:
towards the pump at all points. The diameter of the pipt
should no&ly be greater than that of the mouth of the
pump. The diiser cone used for this configuratior
needs to be eccentric with the upper part horizontal
Check that under normal working conditions the NPSt
(Net Positive Suction Head) is at least 0.5m less thar
that provided by the installation. In order to avoid tht
pump emptying when stopped (and thus needing to bl
re-primed)
it is necessary to
fh afootvalve at the end o
the inlet line or include two elbows in the pipes to forn
a siphon making the pump self priming.
IMPORTANTNOTE: It isrewrnmendedthatthelengthof

hydraulic and electrical connections listed in Chapter; !
'INSTALLATION' have been made. To start the puml
proceed
as follows.
6.1 .-Testing the pump
When starting the pump for the first time or after
i
lengthy period of inactivity it is essential to prime it a!
follows:
- Disconnect the power from the motor or remove th~
batteries.
-Open a vent in the deli~ery pipe before the st01
valve and
fit a vent valve.
- Pour liquid into the outlet pipe until it overflows fror
the vent.

6.2.- Testing the electric motor
-When connecting electrical power checkcarefully thi
the voltage and current supplied by the mains netwol
are the same
as the nominal voltage and
curre
indicated on the motor's name plate.
- Follow the instructions given in the motor manual.

of rotation. This must be the same as that india
ed
by the arrow marked on the pump casing
bracket. If the direction of rotation
is not wrre
two phases in the motor terminal box must 1
changed over (if it is three phase).

13. 6.3.- Testing the diesel or petrol engine
Follow the manufacturer's instructions supplied with
the motor.
.-STARTING AND RUNNING
7.1.- Starting the pump unit
- Before starting the pump unit go through all the
sections of Chapter
6: 'BEFORE START UP'.
- All the valves on the inlet side must be fully opened
and the outlet valve partially closed before starting the
pump. Once the pump has reached operating
speed and all air has been eliminated from the inlet,
the pump may be regulated by adjusting the outlet
valve.
- If the motor protector cuts out on start up the outlet
should be closed a little, thereby further restricting
flow, until the motor starts normally.
/i ThepumpmustNEVER beoperated with a reduced
or zero flow as the recirculating liquid contained
in
the pump will rapidly overheat leading to the risk of
explosion owing to the high pressures that can build
up within the casing. A- Do not operate the pump with the suction or
delive~y valves closed.
8.- PREVENTITWE MAINTENANCE.
8.1.-Pump-motor monitoring.
13
7.2.- Checking during running
Durina the first few Mes of oweration:
Pump wsh mechanical seal:
- Check that there is no leakage whatsoever through
the mechanical seal. If there is the seal must be
checked andlor replaced immediately.
Pump sealed with gland packing:
- If there is no leakage whatsoever immediately loosen
the packing gland until
it drips slowly.
- If there is excessive leakage leave it to settle for 10
minutes then tighten the gland 116 of a tum and leave
to settle for another
5 minutes. Repeat this process
until a drip rate of between
20 to 60 drips a minute is
obtained.
After several hours
omration:
- Check the bearing temperature by placing E
thermocouple on the nearest housing. The norma
temperature can reach 40° above ambient tempera.

A- The pump cannot be accidentally started during
mamtenance. The motor must be disconnected
from power either by removing fuses, unplugging,
opening the circuit breaker etc. or by removing the
battery power supply.
/j - The pump is drained of all liquid and cleaned ovt
with an appropriate cleaner
if the pumped liquid is
hazardous (hot, toxic, inflammable etc).
9.1
.- Drive Coupling
DISMANTLING:
1.- Remove the coupling guard.
2.- Uncouple the pump from the motor (see dia-
gram) Release the motor fixing bolts and re-
move it along with
the male part of the coupling.
3.- If it is necessary to repair the pump release the
nuts joining the casing to the cover and the rear
foot.
4.- If it is necessary to remove the coupling use a
puller. Do not hiithecoupling to remove
itasthis
may seriously damage the bearings or ball
races.
ASSEMBLY:
1 .- Assemble the pump (if it has been dismantled)
and tighten the cover fixing bolts.
2.- Coupleup the motortothe pump. Putthe motor
in place inserting the male part of the coupling.
Put in the bolts but DO NOT tighten them until
alignment has been completed.
3.- Align the coupling (see Manual section 5.2.1).
4.- Replace the coupling guard or protection.

The following stepsmustbe observedif the seal
is to function correctly:
- Extreme care
mustbe taken to avoidintroduc.
ingdirtinto thesealduringhandling, especiallj
on the contacting surfaces. Do not use an)
kind of lubrkan~except clean water. ~le&
using a cloth of the type used by opticians.
- Take care not to damage the rings during
assembly.
- Do not turn the mechanical seal whilst dry.
9.3.- Retainers.
DISMANTLING:
The pump must be completely dismantled to extra(
them (See pt. 9.5, subsection RCOO and RGO1 clos
coupled pumps).
Remove the circlip holding the retainers to the cash(
Do not use a sharp edged tool to remove them fror
their housing as this may damage them.
ASSEMBLY:
Always fi the retainers with the lip towards the insid
of the pump.
1.4.- Packing gland
DISASSEMBLY:
1.- Release the gland.
2.- Remove
thegland packing. If the lantem ring is alsc
removed note its order in the assembly.
ASSEMBLY
1.-Cut the new gland packing to make as many ring:
as are necessary. Viewed from above the cuts ma!
be straight or at an angle of 45' (see diagram).
2.-It is agood idea to leave a little free play (around
O.!
mm) in the when cutting the packing.
3.-Fit the rings one at a time, pushing them
dowl
gently as far as they will go. The rings should b~
introduced wlth the cut placed 90°from that of th~
preceding ring.
4.-Take care to replace the lantern ring in its origina
place.
)I-!

16. 5.- Once the new packing has been inserted check
that the shaft tums freely without any stiff spots.
6.- It should not be possible to screw the gland
infully,
insert more rings
if necessary to prevent this.
7.- Gently tighten the gland nut. 8.- Todeterminethenecessarypacl6ngtightnessfollow
the instructions given in section 7.2 of this Manual.

ASSEMBLY.
To assemble the pump follow the above instructions
in the reverse order.
Be sure to
put eaccof the parts back
in the right
place, especially the seal and impeller compo-
nents.
7ighten the impeller nuts fully.
0.- LUBRICATION
RC and RCV series pumps are Vied with either friction or
roller bearings which are lubricated by the liquid itself
making it unnecessary to take any additional steps unless
problems arise.
The models which are fitted with friction bearings are:
RGOO. RC-01, RC-1, RC-1%. RG2
RCV-1. RCV-1% RCV-2
The models using roller bearings are:
RCPR, RC2RD, RC9R, RC-4R
The models comprising the RCA series use external
grease lubrication.
Before lubricating the pump ensure that
- The pump is stopped and there is no risk of its
accidentally starting.
- The bearing housing temperature is less than 40°C
so that there is no risk of bums to the hands. Uses
thermowuple to measure tlts temperature.
10.1.-
Greasing (RCA only)
The pump leaves the factory with the bearings ready
greased for the first
1000 hours (approx.) operation.
For lubrication purposes a table has been included.
Quantities shown are grams of grease to be applied
to the greasing points approximately every 4000
hours of operation for pumps of the given shaft
diameters (measured on the coupling side).
1 ; 1 GREASE I
QUANTITY (gr)

17. 10.1.1.- Changing the grease.
When changing the grease the bearings must
first
be stripped down and their seats in the base
thoroughly cleaned to remove all traces of the old
grease.

against a closed discharge valve for a short time (ma. 5-10
minutes and at a max. temperature of 1300 C).
Otherwise there is a risk of damage to the pump and at
worst, of asteam explosion. If the pump room is unmanned,
the installation of a safety device is highly recommended.

30. 1. Introduction
It Is vltally Important to Install the pump correctly in
order to achleve the ultimate performance and long
Ilfe. Correct lnstallatlon deoends on comoivino wlth ., -
the following points:-
2. Design
DESMl MODULAR S is a single-stage self-prlmlng,
centrifugal pump wlth stainless steel shaft and me-
chanlcal shafl seal. The small pumps, sizes 532.25
110, 550-32-135, and S50-32-220, have open Impellers,
all other sizes have closed impellers.
The pump Is sultable for clean or polluted liqulds wlth
temperatures ranging from O0 to 60°C.
The pump has horizontal Inlet on the centre llne and
vertical outlet at the top.
The back of the Impeller Is equipped wlth relief blades
In order to reduce the axlal load on the bearlngs at
.
high revolutlons and pressure.
Relief holes in the Impeller ensure circulation of lip
uids for the shafl sealand prevent, under normal cori.

The Dumos are oartlcuiarlv suitable for the oumolno
of water in connection wlth coollng systems; cool in^
of dlesel englnes. Irrlgatlon, water lowering, and flre
protection, as baliast and biige pumps, and-as pumps
for fish farms, water works, salvage contractors, ar;
mles, and navles.
The pump should be Installed on a base plate with a
fiat surface to avold dlstortlon. The centre llne of the
shaft Is to be horlzontal.
Bore
H7
Is recommended If the pump is to be fltted
wlth
a V-belt pulley, to
facilitate the fitting, the hub
can be heatedto~aboutlOOO~;..~ . . ~ ~ ~~- ~~ . ~. .. .
The V-belt oullev can then easllv be slid onto the shaft
towards the shoulder. ~lternatfvely, a belt pulley wlth
a taper lock bush can be fltted.
When selecting the V-belt pulley, It is lmportant to ob-
serve the lnstructlons glven in the DESMl nomograms
for the pump size In questlon. If In doubt, ask DESMl
to advise.
If the pump Is to be drlven by a motor through a fiexl-
ble coupling, pump and motor should be mounted on
a common base piate.
Please note the followlng:
1. Avold dlstortlon In the base plate.
2; Avold dlstortlon In the piping.
3. Make sure that pump and motor are correctly
allgned.

4. Plplng
The suctlon hose should be fltted very carefully as -)
even thy leaks may lmpalr the self-prlmlng. Water-
tightness may be checked by a pressure test.
The suctlon hose should be as short as posslble.
When selectlng make sure that the veloclty of the
water does not exceed
2
mhec.
Use a stralner when PumDlno oolluted Iloulds. The
stralner must be fltted with asieve wlth a'sectlonal
area of flow of 3 x the area of the stralner. Mesh slze -
see data sheet for pump In questlon.
The pressure hose should be sized for a velocity of
water not exceeding 5 to 6 mlsec. In order to ensure
bleeding of the pump durlng prlmlng It is essential
that the pressure he Is made so that traps in the
pipework'are avolded. During prlmlng the pump can-
not produce enough pressure to overcome traps.
The plplng should be arranged so that posslble
stresses resuitlng from~fluctuatlons In temperature
are not applied to the pump.
Tools for Dismantling and Assembllng of Pump

31. 5. Startlng
5.1 Llquld Filllng
A self-prlmlng pump must flrst be fllled with llquid.
Llquld fllllng takes place at the top of the pump
caslng. Remove the plug, flll the pump, replace the
plug, and the pump Is ready for use.
The liquid also serves as coolant for the shaft seal.
5.2 Start-up
Before start-up do the following:
1. Check that the shaft can rotate freely.
2. Check that the pump caslng
Is fllled with water.
3. Start the pump for a moment to check the direc-
tlon of rotation.
If the dlrectlon Is correct (clockwise when viewed
from shaft end) the pump may be started.
6. Lining-up
It is often
dlfflcult to calculate the manometrlc dellv-
ery head In advance. It Is, however, declslvely lmpor-
tant for the quantlty of llquld dellvered.
3 I
A considerably smaller dellvery head than expected
.will increase the quantlty of llquld dellvered, causlng
Increased power consumption, motor overload, and
perhaps cavltatlon In the pump and the piping. The
Impeller may show slgns of heavy eroslon caused by
cavltatlon (corroslon), whlch may at tlmes render an
impeller unfit for use In a very short tlme. Not unusu-
ally do slrnllar eroslons occur in pipe bends and
valves elsewhere In the plplng system.
Therefore, it Is necessary to check either the quantlty
of llquld dellvered or the Dower consum~tion of the
pump, e.g. by measuring v'oltage and curient level on
the motor. Together wlth a readlng of the counter
pressure a determinatlon of the ouantltv of water de-
ilvered can be compared agalnsi the characterlstlcs
of the pump.
Should the pump not functlon as Intended, please
proceed accordlng to the followlng fault-flndlng list.
Bear In mind. thouoh. that the ourno was carefullv
checked and testedit'our factoG and that the malo;-
Ity of faults stem from the plplng system.

No workmay be carried out on the equipment eicept
when it has been withdrawn from service and fully
stopped.
Once any work on the pump is finished all protection
and safety measures must be replaced and put back
into operation.
Refer to individual manualsfor maintenance of palls of
the unit, such as the motor. All manufacturer's safety
instructions must be followed,
All auxiliary connections must be reconnected and
made ready for operation before the pump is set
running.
When the pump is being started for the first time the
appropriate instructions should be followed.
The use of gloves is recommendeddurlng handling ol
this equipment as it contains many small pieces such
as nuts, bolts etc. which could cause minor cuts and
abrasions to the hands.
The following instructions are intended to avoid oper-
ational hazards in the use of thls equipment:
Al The oum0ed liouid mav cause burns, ooisonino 01

following protective measures:
-All openings are plugged with plastic or adhesive
stoppers.
- Wahthe exceptlon ofthose in stainlesssteel, allthe
visible mechanical suriaces are coated with a tem-
.pxary layerof peel olf varnlsh.
- To avoid movement durlng handllng and transpor-
tatlon the equipment is securely packaged.
Depending on the customer's requirements the
pump may be packed in an open wooden crate, in

53. Mode of use:
- Place the equipment over its base.
- Drill holes inthe base inthepointscorresponding
to the anchoring points into which to fit them.
- Level up the unit. ...-. _: .
- Oncethe equipment is located on its foundation
and the bolts are Vied into the holes, pour
cement (do not use quick setting cement) into
the holes and allow
48 hours for
fi to dry.
- Level up again and tighten the bolts.
.1.2.- Levelllng up
Aconventional spirit-level may be usedto level upthe
unit. The unit must be levelled up both lengthways and
.
crossways.
If it is necessary to level the base plate by using
wedges small shims of cut sheet metal should be
used. Bond them with
askin of cementto preventthem
from deforming when the bolts are tightened.
Once levelling has been completed it iswiseto weldto
each of the nuts to its corresponding bolt so that it
cannot become loose during operation.

diameter than the mouth of the pump. A gate-valve
should also be fitted to regulate the flow and avoid
overloading the rnotor. The use of a check-valve is not
recommended as it makes self-priming diiicuk. If one
is used, it should have the lowest possible opening
pressure.

before the pump is started and during running so
as to avoid the risk of whiplashes caused by the
pressure generated by the pump.

67. Introduction .
Pump Assembly Mounting
The Mission Fluid King Oilfield Products Cenfifugal Pump is shipped
completely assembledand ready for operation. The impeller has been
mrefully lined up, and the shdt bearinss have been locked in olace to
pmvide~proper clearance within the housing. The shat should be m-
Wed by hand before installation to make sure the impeller cleamnce
has not been dislurbed during shipment. Ifthe impeller scrapes,
it must
be reset The Pump may be mounted on a cast imn or steel plate and
may or may not be connected to the driver. The base plate must be well
supported on a solid foundation, levelled, and firmly placed.
External
piping should be supported independently to ali~n with suction and
discharge flanges ofthe pump, sias to ward tranhting pipe strains
to the pump. Complete dimensions
are given in the installation plan furnished with each pump.
Installation and Startup of Pump
Packages
General Instructions
Operate the pump only in the performance
mnge for which it was de-
signed. When operating In drllling mud, prevent pacldng drippage from
clogglng the drip pan. The buiid-up
can allow mud
to go amund the
slinger and front seal into the bearings.
Adjustthe pacldng so that a small amount of leakage remains for lubri-
cation and cooling.
Installation
The pump should be located near the liquid source so that the suction
line may be short and direct The pump should be located below the
level of the liquid to eliminate the
necessity of priming.
Coupling Alignment
Good
service life of the pump and driver depends upon good alignment
through the flexible coupling. Ithe elecbic motor
was mounted by the
manufacturer, the pump and motor were in alignment when shipped.
The alignment between the driver and pump should be inspected
affer
installalion to ensure that~sportation or other handling has not caused
mis-alignment of the unt Poor alignment may cause failure of the cou-
pling, pump, or motor bearings, or of either shaft
The recommended pmcedure for coupling alignment is by the use of a
dial indicator,
as
illusbated in Figures 1 and 2. The dial indicator is
attached
to one coupling,-half with the indicator
button resting on the
O.D. of the other coupling, half to measure Met misalignment To
measure angular mis-alignment, the indicator
is
positioned so that the
buttons
rest on the face, near the O.D. of the other coupling half. Rotate
the shaff and dial indicator one full revolution while the other shall re-
mains
Wonary and note the 1.R. Unless othenvise specified by the
coupling manufacturer, offset misalignment should be limited to.005
inches TI.R Adjust alignment by loosening driver or pump mountlng
bolts and retightening or Shimmlng as required;
Measuring Offset Misalignment
Figure
1
Measuring Angular Misalignment
In
areaswhereadial indicatormgement is notamilable,anadeq&
job
of alignment can be
donewith asbaight edge. This method is espe-
cial~ useful
if the coupling used
contains an all rubber drive element,
which
can be used
wilh up to 5 times the misalignment of metal drive
couplings.
To check offset misalignment, lay the sbaight edge in line with the
shafts on
the' OD's of the coupling halves. There should be no gaps
under the
W~ght edge. Check two locations
90 degrees
apart Angular
misalignment
can be checked by measuring the gap between coupling
half faces. There should be no more
than a
1/64Qap under the sbaight
edge or 1/64" variation in the gap between coupling halves.

68. Bearing Discoloration
A brownish or bluish discoloration of the races and balls indicates that
the bearing operating temperature
was excessively high, to the extent
that the bearing lost its physical
pmperties and was nolonger opemble.
Retainer ~ailure
The bean'ng part that first indicates distress in lubrication failures is
usually the retainer, where the greatest amount of rubbing action takes
place.
.
Cause
Dirty Lubrication
Contaminants found in lubricants
offen act as an abrasive compound
which will lap or polish ball andmce surfaces, increasing the pmbabil-
ity of early failure. Always be sure you use good clean lubriwntfmm a
tube and NOTfmm an open bucket
Too Much Lubricant Awry wmmon mr In the maln$nance of machinery is the lendency
todubd& Hthe bean'ng reservoir is kept constantly full of grease,
the friction heat developed within the lubricant can not get out and will
cause
its rapid deterioration.
Wrong Kind Of Lubricant
After experimentation with many types of lubricants, the equipment
manufacturer
rmmmends those whlch he feels will pmvide ideal lu-
brication life under g~en operating conditions. In as
far as
availabilii
allows, you should use the same lubricant or

Re-Packing The Stuffing Box
MOST EARLY PACKING FAlUJRES ARE CAUSED BY OWmGMOVlNG
OR POOR INSTALlAllON.
Packing Appearance
If the pacldng being removed is hard and brittle, it has been run dry
sometime during its life. This is often done In the first hour of service.
The pacldng
has more
abilily to gmw with heat during its early life. Even
if the Packing is adjusted just right before starting the pump, in the first
few mlnutes the packing will gmw with heat and become over-tight It
then will'run drop tight and bum the packing. ONCE PACKING IS
3
BURNED
IT WILL NEVER SEALRIGHT AGAIN. On new packing let it leak
more in the first few hours. then adjust
it to 10-12 dmps per minute.
Correct Installation Of Packing:
Make sure the box is clean of all old packing and the plastic
lantern
ring. Bend a wire and pull
it down the shaft or shaft sleeve to be sure it
is smooth for good packing life.
Placethe firstthree ringsof packing in the fmnt of the boxwith thesplits
alternated. The first split to be down, the second split up, and the third
split down. Then ins& the lantern ring and compress this assembly
fomd wlth the gland halves. Then install the last two rings split up
then split down.The object is to have the last split down so leakage will
drip down, not run along the shaft and maybe into the bearings.
Merlhepacking has been installed, install the packing glandand tighten
hard to compress the pacldng assembly. Back off the gland bolts and
re-tighten only finger tight
Adjusting The Packing:
Paddng must have wollng, therefore it must leak When adjusting the
pad4ng always adjust only one flai on the nut at a time, waiting for the
packing to heat before adjusting tighter. ME PACKING MUST
LEAK
10-12 DROPS PER
MINUTE TO REMAIN COOL
Lubrication And Cooling Of Packing With Water
it is best to inject Wr into the lantern ring fmm an Edemal source on
drilling mud. This will
keep most of the solids out of the packing.
Grease Lubrication
Of Packing
H water can not be used, the next best addiUon to the packing would be
grease fmm an automatic spring loaded
grease cup. This
will help keep
the pacldng sot There isavisual indication when the cup no longer has
any grease. The stored grease normally lasts a week or more if the pack-
ing is adjusted
correclly.
Installation Of Replaceable Parts
The fluid end is so consbucted thatthose parts subject to wear may be
readily replaced in the field. To replace the wing, wear plate, and im-
peller, the following pmcedure should be followed:

and then lock

direction of pump rotation, and locking
it with the set screw.
Operating Conditions
Space is provided for
three rings of 318" square packing atthe impeller
side of the Lantern Ring. Packing should be of a gmde suited to the
operating conditions
of the pump; square braided
pacbng is regularly
furnished. Excessive tightening of the packing gland nuts causes shaft
wear, is unnecessary, and should be avoided. SligM leakage, appmxi-
rnately 10-12 drops each minute, is desirable toactasa packing lubri-
cant tf a corrosive or abrasive material is pumped, gland water at a
maximum pressure of
15 PSI should be piped to the Lantern Ring by
way of the
114" pipe connection and allowed to leak thmugh the pack-
ing for lubrication. The drip
pan under the shaft is provided with two
I/? pipe connections to drain off this leakage.
A grease fitting may be put in the 114" tapped Lantern Ring connection
if grease lubrication of the packing is desired. Water pump grease is
usually satsfactory.
Lubrication
The pump is shipped with sufficient lubricant packing in the bearing to
assure tmuble-h ooemtion for normal sewice li. Under nod op-
erating wndiions, no lubricant needs
to be added to the bearings. If
the
ourno is disassembled, it is advisable to pack the bearings with
greaie pimperly before misembly. Packthe bearing thmugh approxi-
mately one-half of
its circumference.
It is not necessary to put grease in
the bearing cap or pedestal.
The bearings normally
may run at temperatures up to 180 degrees
F,
without injury. A temperature of 180 degrees F is hotter than the hand
can stand to touch for more than a second or two, but will not bum off
the paint The ternpenlure may be determined by sticking a ihermorn-
eter to the bearing cap wiLh heavy grease and leaving it for twenty (20)
minutes.
Should the bearings run hot, immediate service is necessary. This ab-
normal condition indicates that
(I) the bearings may not be properly
installed.
(2) pump and
motorare out of alignment, (3) excessive grease
has been forced into the bearing housing,
(4) insufficient grease is
present in the

Thls- thi@cular operating condition.

70. Piping (General)
Piping should be anchored independently of the pump and as near to it
as possible. Pipe companion flangesshould line up naturally with pump
flanges. Do not draw the pipe to the pump with flange bolts.
Piping (Suction)
Pmperly
selectedand installed suction piping is extremely important to
eliminate vibration and cavitation in the pump. Vibration can cause
packing pmblems, or undue bearing loads. The suction should be equal
to,or larger Ulan the pump su.ction.
Apositive shut-offvalve of atype to cause minimum lutbulence should be
installed in Me suGon line to permitthe closing ofthe line and remml of
the pump for inspeclion and maintenance. Hm, the capacRy of a
mbif@ should never be adjlsted by UuuUIing the suction.
The suction line should have a straight section into the pump ofa length
equivalentto at least two times the diameter of the suction line.
For tempomy hook-up, where flexible hose is used,
a non-collapsing
hose is essential since the suction line is often below
ahnospheric
pressure. A collapsing suction line will result in below designor
complete loss of flow.
Piping (Discharge)
A positive shut-off valve should be located in the discharge piping to
permil inspection and maintenance of the pump.
All piping should be independently supported and accurately aligned.
The pump must not support the weight of the pipe or compensate for
misalignment
If operating conditions are not known with sufficient accuracy, it will be
necessary to pmvide athrottle valve in the discharge piping to ensure
that
the pump operates at the design point
If the pump is connected to a pressurized system, it is important to
install a check valve between the pump discharge and the thmttling
valve. The checkvatve will prevent back flow thmugh the pump.
Preparation for Operation
Check Rotation
Most pumps purchased are clockwise when
viewed from coupling end.
The correct mtation can be found by an arrow on the casing.
', > ..,, :.
It is very importantthat the pump is not started up and !hen go &see
if Me pump is turning the correct mtation. The packing or mechanical
sealcan run dry and be destroyed.
The best way to check rotation is to disconnect the coupling. before
testing rotation, but it can be checked without disconnecting. the
coupling. One person should be at the pump watching the shaft, while
the second person pushes the start button on the starter and
immediately pushes the stop button so the shaft barely tums over.

TYPE OIL GREASE
S 3500 2400
W 3500 2400
Grease Lubrication
Most pump bearings are pre-lubricated with grease from the factory,
and in moderate speed, low temperature application may not need
lubrication throughout the
life of the pump. Plugs are installed where
the grease fittings
are to go. In
heavy loads and hot applications, the
bearings should be re-lubricated at regular intervals-for maximum
bearing life. The bearings
are lubricated with Chevmn
SRl-2 grease at
the factory. When relubricating, the Chevmn grease would be the best
choice since mixing greases sometimes causes incompatibility
pmblems. The her premium bearing greases are &on Unirex N2,
Chevmn Polyurea V 2, Tewco Marfak Multi-Purpose 2, Shell Mp2, and
American Oil Company's Rycon Premium 2 p
When using the five premium bearing greases isted above or their
equivalent five shots of grease with a standard sked hand operated
grease gun,
in each bearing every 2-3
MOErmS will be sufficient in a
twenty-four hour openlion. Reduce for lesser operation. The pump
bearingsshould be lubricatedabout on the same scheduleasthe motor
bean'ngs.
NOTE. AUTOMATIC OILERS are set at the factory to the lowest position.
This setiing will pkce the oil level just below the center of the bottom
ball of the bearing when the housing is level. Higher levels may cause
churning and overheating of the bearings; lower levels may p.mmvide
insufficient lubrication and promote rapid wear. The correct oil level
will be visible at the center of the sight oil gauge.
Standard pumps
are shlpped with empty oil resarmlrs. Oil must be
added before operating the pump. Attach the oiler to the bearing
housing,
fill the bottle wlth oil and place it in
position. Refill the,boffle
until oil remalns visible in the bottle. Oil should not be added to Qe
reservoir except thmugh the oller bottle.

71. A good grade of SAE 10W30 oil may be used. Theair vent should be
kept clean to prevent pressure build-up because of normal heatingthat
occurs in operation. A Trico optomatic oiler No.
EB-64 with a 4
or
capacity bottle is used. The correct bottle must be used with the corre-
sponding oiler body.
Priming
Be sure the pump has fluid in
its casing before running. ii the pump is
operated without fluid, the mechanical s&l or packing
can be
desboyed
in one minute. Vent air fmm the suction line and fill with liuuid. Start
pump with discharge valve cracked open. After discharge prekure sta-
bilizes, gradually open discharge valve to required position. ii flow is
lost, close discharge valve and wit a few seconds for discharge pres-
sure
to build. Do not run the pump with suction valve closed ANYTIME
and with discharge
valves closed only for short periods of the.ihe en-
ergy going into the pump heats the fluid in the casing.
If the pump
needs
to
opemte shut in some of the time, be sure to have a small line
(114Qr 1P) back
to the suction tank between the discharge valve and
pump for cooling.
Pump Records
Maintain data cards or pump records whenever possible. This will
pm-
vide
ready access to information for ordering spare parts, and for evalu-
ating pump and mechanical seal performance.
Information to be included on these records should be:
Pump she
Pump model number, impeller diameter, material of construction
Mechanical seal manufacturer, type, code, and drawing number
Motor horsepower and speed of operation
%ME ~0fldifi0nS
Frequency
of
opemtion
Record
of maintenance, including parts usage and general
condition of pump
Nomenclature and
part number of replacement items
Loosen Packing On Startup
The gland
bait ruRshould be only ffn~w ti~ht N& packing will expand
faster with heat than older packing. Therefore, new packing must be
adjusted more slowly than old packing: Too tigM and
it will not leak
Wth no cooling lwill hum and be no good for sealing.
Trouble Shooting Procedures
WHERE EXCESSME Pdcking Leakage and Rapid Packing Failure oc-
curs. the shafl or shaft sleeve nay be worn out Remove the pacldng.
Slide a wire, with
a
short section of the tip be6 90 degrees into the
stuffing box Runthe stylus tip of the wirealong the shaft If deep gmoves
are
noted,theshaRor shafl sleeve must be replaced. Excessivetighten-
ing of the packing will cause tapid shaft failure.
6
PACKING BURNED; If the packing is bumed and hard when removed, it
has been over-tightened at some time and the lack of leakage caused
the packing
to bum. Once packing has
bumed and is no longerand sot
and pliable,
it will not seal
pmperly. inib'al over-tightening and attempt-
ing to run pacldng without leakage will cause Me packing to bum.
Bearing Failures
EXCEPT FOR CAVITATION PROBLEMS, BEARING
FAlWRE IS THE
GREATEST CAUSE OF INCREASED WMP OPERATING COST.
IF YOU CONTINUE TO RUN A PUMP WHEN BEARING FAILLIRES OC-
CUR, THERE IS
AN
EXCELLENT CHANCE THE WHOLE WMP MAY BE
DESTROYED. Therefore
it
isvery importantto change the bearings when
failure
STARTS. If you wait for complete failure, other fluid end parts
will be damaged.
Bearing failure is more often caused by LUBRICATION
FAILURE than by
normal bearing wear.
Identification of Bearing Failure
Abnormal Temperature Rise
The first indication of lubricant and bearing failure is a rapid rise
fmm
normal operaling tempemre. You
can not hold your hand very long on unsab'sfactory tbmpemtures. ti you can hold your hand on the bearing
housing about 5.seconds, the temperature isabout 160 degrees F. (suit-
able for most pumps). IF YOU CAN NOT HOUI WUR
HAND ON THE BEARlNG HOUSING FOR 5 SECONDS OR IFTHE BEARING HOUSING IS
SO HOT YOU DO NOT
WAN TO PUT YOUR HAND ON IT mu PROF
AEW HAVE LUBRICANT AND BEARING FAILURE.
Grease Appearance
t the grease is sMf or caked and changed in color, it indicates lubrica-
tion failure. The original color will usually turn a darkshade or jet black
The grease will have an odor of burnt petmleum oil. Lubrication will be
lostasa resuitof lackof oil IN CASES OFUMlUM BASE GREASESTHE
RESIDUE
APPEARS
UKE A GLOSSY BRllTE VARNISH. WHICH WILL
SHAllER WHEN PROBED Wml A SHARP INSTRUMW.
Grease is a m'kture of oil and usually soap. When a pump M othw
equipment sits a long lime without rotating the oil separates and runs
out of the bearing housing.
It may look like grease
isstill in the bearing,
but
it will not have any lubrication properties.
Noise
Lack of lubrication is soon accompanied by awhistling
noise, coupled
with the rise in tempemture. If not comcted, the b@ng temperature
will continue
to rise and the intense heating will reduce the bearing
hardness.

72. Long Term Pump and
Motor Storage
1. Pump packages should be stored indoors in a clean, dry and
protected environment
2. The storage area is to be free from any vibration and from
exbemes in temperature.
3.
Motorand pump shahareto be rotated manually every2 months.
A record of the rotation should be made.
4. Grease in the motor and pump bearings is to be purged at the
time of removal fmm storage, making sure that an ample supply
of fresh grease is in each grease cavity.
5. Motor winding should be
rnegged at the time equipment is put in
storage.
At the time of removal fmm storage, the resistance
reading must not have
dropped more than
50%
from the initial
reading.
Any drop below this point necessitates
eleckical or
mechanical drying of the motor windings. Condensation fmm
hot days and cool nights
can fill the motor half full of water. This
is
a
greater potenthiproblem in damp areas.
6. il the pumps are to be stored outside, the pump suction and
discharge openings should be sealed to prevent any water fmm
entering the pump housing, causing
rust of the fluid end during
storage.
Recommended Lubricants
Although the correct grease to use depends on the specific pump ap-
plication, the following list of lubricants represents some grease
manufacturer's recommendations for general
service. similar type
greases fmm other reputable grease manufacturers are also suitable.

87. .2. GENERAL INFORMATION
On receipt, please check that the unit 'is complete and undamaged. In the event of shortage or
damage, the carrier and the supplier must be advised immediately, for the purpose of submitting
a claim.
In accordance with the product liability act it is our
duty to draw yonr attention to
the following risks if the pump is misused
It is imperative that the engineers involved in assembling and servicing are familiar with
the current operating and maintenance
manual before installing and starting-up the
pump, they must be technically
qualified,
The user is responsible for observing the safety instructions in this manual.
General safety
insmctions including local safety and operating regulations do not form
part of the pump manual. The user
is
fully responsible for complying with these
regulations.
The erection and the service of ROTAN pumps must be cauied out in-strict accordance
with existing regulations for mechanical and electrical engineering.
The pump must only be used in accordance with the operaring conditions specified on
customer's order. Any deviation
must be with the manufacturer's consent
The operating and maintenance manual covers standard designs only.
Variants in
construction, erection, operation and maintenance are not included.
The supplier
must be contacted in the event of any necessary information not being
found in the manual
The service life and the specified properties of the unit are limited by wear,
comosion, andbreakdown dependent on the operating conditions. It is the user's duty to
ensure
that regular service is carried out and that parts are replaced as and when
necessary. The pump should be stopped
if it is operating
abnormally or if there is any
visible damage.
Installations which can cause personal injury or material damage in the event of
breakdown must be provided
with reliable and regularly tested alarm systems
andlor
spare
units.
AU units which are in contact with foodstuffs must be thoroughly cleaned before use.
Non-observance of these. warnings and operakg instructions can
lead to complete
breakdown and possibly result in personal injury and material damage.
The manufacturer
is absolved from all responsibility if the instructions in this operating
and maintenance manual are not adhered to.
If the pump is sent on to a third party, it is absolutely essential that it is accompanied by
this operating and maintenance manual plus operating conditions specified in the order.

88. A
Do not put your fingers into the suction/discharge ports of the pump when handling
the unit.
The pump must be handled carefully and not exposed to hocks and damage.
Lifting
is
canied out using stable suspension points so that the unit is in equhbrium.
Lifting straps must not be placed over sharp edges.
Wbere long storage is envisaged steps must be taken to avoid corrosion and drying out This can
cause seizure of the nkhanical seal seats, which in turn will cause damage to the seal, when &e
pump
is started up.
Base coat or top coat
is
applied on the extemal - not stainless - surfaces of the ROTAN pumps.
The pumps are usually lubricated with machine oil kom the factory; pumps for foodstuffs are
heated with a food approved lubricant

89. 4. PUMP TYPES AND VERSIONS
The ROTAN pump is a gear pump with an internal idler gear in mesh with a main rotor.
B'
The operating principle is shown below:
The modular design of the ROTAN series allows a large number of pump configurations. It is
therefore possible to adapt the ROTAN pump for a specific duty. fl
p
AU ROTAN pumps can be provided with a relief valve tb prevent the build-up of excess
pressure. Most of the pumps can be
fitted with a
heatinglcooling jacket for the pump section and
shaft seal
All standard pumps allow reversible pumping, the direction of flow is determined only by the
direction of rotation of the motor.
The pumps are grouped
into 5
main series:
F
HD: Heavy Duty.
Par$ in contact with the liquid are manufactured
in cast iron and
steel
CD: ChemicalDuty.
Paas in contact with the liquid are manufactured in stainless steel.
PD: Petrochemical Duty.
Paas which suround the liquid are mauufactured in steel. L
HD, CD, and PD are each bare shaft units coupled to a motor and mounted on a common base
plate. Shaft sealing arrangements vary, i.e. stufting box, a single
mechanical seal and double
mechanical
seals in tandem or back-to-back
i
i
GP: General Purpose. L
The pump end is identical to that of the HD punip, but is direct coupled to a mge
mounted motor. The motor must have the located bkhg at the drive end The GP can
be fitted with
a stuffing box or a single
mechanical seal.
: Environmental Duty - magnetically coupled pump.
Paas in contact
with the liquid are manufactured in cast iron, stainless steel or steel.
The pump
has a bare shaft and is coupled to a motor and mounted on a common base
plate.

90. 42 CONFIGURATIONS
The configuration of the pump in question is shown on the nameplate (see 11.1):
5) Material codes for main parts/wetted parts my clglm~~~mnp.:

91. 7 1
Cont3gnrations (supplement to item 3 of the page before)

92. TECHNICAL DATA
The ROTAN pumps have three types of shaft seals, viz.
- Soft shaft seal
- Mechanical shaft seal
- Magnetic coupling
The type of
seal fitted in the pump is indicated on the nameplate (see 4.2).
5.1.1 SOFT
SHMT SEAL
A packed box requires constant maintenance, a leakage of 10-100 drops per minute being
allowable.
If the
stuEng box is tightened too much, there will be an increase in frictional heat,
which can cause hardening and increase wear on the sh&
5.1.2 MECHANICAL SEAL
Mechanical seals are virtually leak-&ee and require no maintenance. Pumps with n&&cal
- seals should only be run after bleeding and being med with liapid because if allowed to +dry
the seal faces of the mechanical seal will be damaged. Self-priming up to one minute's ddon
however
is allowed.
5.1.3 MAGNETIC COUPLWG
The magnetic wupling is I&-6ee. The magnetic wupling separates the pump fiom the drive
shaft
Magnetic couplings are designed specifically for
each
ROTAN pump so that its pedormance
corresponds to the specifications called for in the order. The pumped liquid acts as the cooling
agent Depending
on the speed and viscosity the maximum temperature rise of the liquid passing
through the coupling for cooling will be
30°C.
Steps must be taken to ensure that the motor
cuts should the magnetic wupling slip because of
overload.
5.2 BEARINGS
As a general rule the pumps are fitted with sleeve bearings, the exceptions being
HD .. EM(see 4.2) and GP .. EM, which are fitted with "sealed for life" ball bearings. These
bearings, items andNB (see 11.2) are factory lubricated and need no attention.
The sleeve bearings of the U configuration (see 4.2) are lubricated by the liquid pumped, whilst
the M co&guration requires separate lubrication. See item 8.lregarding lnbrication.

93. 5.3 HEATING
Where heating is required for the pump, a heating jacket can be provided for the *ant andlor rear
cover, configuration
D and K (see 4.2).
The heating jackets are designed for a maximum
worldng pressure of 10 bar.
5.4 OPERATIONAL CONDITIONS
The limitations (RPM, pressure, temperature, and viscosity) stated
in this section are to be
considered as recommended
maximum values as the individual ROTAN pump can have further
Limitations, e.g. on account of the
medium pumped, the shaft seal chosen and in particular
tlie
motor laid out
5.4.1
RPM
The
maximum RF'M of the
ROTAN pumps for viscosities below 400 cSt are as follows. In the
event of
higher viscosities the RF'M is reduced to avoid cavitation
Pm size
5.4.2 DFE3EWUL PRESSURE
The total overpressure (inlet pressure + Werentid pressure) may not exceed.
- 16 barfor thetypes 26 - 81.
- 10 bar forthe types 101 - 201.
The nwes below illustrate maximum permissible differential pressure for ROTAN pumps used
for pure, non-abrasive
liquids. NOTE: the exceptions
are:
- Configuration "MM and "MMP! with the main bearing placed between the shaft seals -
maximum pressure 6 bar.
ED81EH - maximum pressure 8 bar.

5.4.3 SUCI'ION HEAD. NPSH
In order to ensure a cavitation-free pumping, the suction conditions should be such that the
pressure on the inlet side
is higher than the
NPSH, of the pump at the specific operating
conditions.

95. The limitation of the operating temperature is, among other things, dependent on the
elastomers used
in the

Pumps with standard clcamices are limited to a maximum temperature of 150 "C.
The HD, CD, and PD types provided with special, clearances (the codguration includes
a "T" - see 4.2) can in certain cases be used up to 300°C.
The ED pumps must not be exposed to a temperature exceeding 25O0C, including the
temperature rise in the magnetic coupling
- see subsection 5.1.3; Viton is standard elastomer.
ROTAN pumps in
standard
wnfiguratiom can be used in the viscosity range 1-7.500 cSt In the
event of special clearances (T forms part of the designation - see 4.2) the HD, CD and PD types
can be used up to
75.000
cSt; the EO type is limited to 10.000 cSt
55 PROTECTIVE DEVICES
The unit should be provided with suitable protective measures so that pump and motor are not
loaded beyond the hits stated in the order.
5.5.1 VALVE
As a result of the ROTAN pump operating against a closed discharge outlet an unlimited
pressure build-up
can occur.
This means that the pump, piping, and valves etc. should be
protected by a ROTAN relief valve
as a
minimwi safeguard.
The relief valve leads the pumped liquid from the discharge side back to
the suction side when
the set pressure
is exceeded. The pump must not operate in "by-pass" mode for a long time, as it
will cause heating of both liquid and pump.
The standard relief valve
(confguration R) only protects in one pumphg direction. The adjusting
screw of the relief valve should point to the kction side of the pump.
In the case of a valve with
a vertical adjusting screw, it shall point to the pressure side of the pump.
Nody the valves are
provided with a "p" for pressure side and a "s" for suction side.
The opening pressure should be
1-3 bar over the normal operating pressure.
The adjustment of the safety valve
from factory
may appear from the order.
If the valve is
readjusted, the adjusting screw must be re-wrapped
in thread tape.

96. Setting dimensions for the relief valves are shown in the following chart

PUMP SIZE
6. INSTALLATION
The following should be considered to avoid operating problems:
- The base must be such that the unit is solidly supported and is not pre-seessed when
erected
-
There should be sufficient space around the pump for service. Below is stated the
minimum distance to a wall to enable dismmtling of the kont cover.
-
The suction height of the pump (see 54.3) should be taken into consideration
-
Normally the pump is mounted horizontally. If the pump is placed with the flanges
upldovk, it will not self-prime. Normally the pump must be installed so that the shaft is
horizontal.

99. Pipework
- All pipework must be free of any conramination.
- Plugs in the connecting branch of the pump must be removed.
- The pump must be installed in such a way that stresses in the pump casing caused by the
pipework are kept to a miaimurn. Permissible loads on the pump flanges appear £rom
subsection
5.7.
Mounting pump and motor:
- Alignment of pump and motor is to be checked after the installation Procedure is
described in subsection 9.6.
- Check that the pump shaft rotates easily and regularly.
- The coupling between motor and pump is to be completely guarded.
Wiring:
- The wiring is to be carried out by an authorised electrician in accordance with local
regulations.
- Check suitability of voltage available with that on the motor plate.
- The motor overload switch is to be set at the maximum rated current of the motor.
- Check direction of rotation of the motor. If the direction of rotation of the motor is
clockwise then the flow direction is from right to left seen from the motor side.
Relief Valve:
- Check that the valve points in the correct direction (see 5.5.1).
Control:
- The control &quipment is to be adjusted and checked.
7. ' STARTINGUP
Because of the sleeve bearings and shaft seals, ROTAN pumps can only be permitted to rim
without a flow of liquid for the short period of self-priming. The faces of the sleeve bearings and
shaft seals must not be allowed to become
dry during prolonged storage.
When starting-up, please
check
- that shut-off valves on the inlet and outlet sides are open.
- that on fist start-up the pump casing is filled with a small quantity of liquid to ensure the
self-priming ability.
- that coolinghbricating devices etc., if any, are operational.
- that the control equipment functions.

100. - that the direction of rotation is comt If the direction of rotation of the motor is
clockwise, then the flow direction is from right to left seen £tom the motor side.
- that the pump is drawing the liquid.
- that the pump does not vibrate or is noisy.
- that the pump does not leak
- that a soft seal, if any, leaks 10-100 drops a minute - see section 8.2.
- that the relief valve opens at the required pressure.
- that stuffing box and beatings do not give overheat; lip seal rings will normally cause a
heating of the shaft during the time of &g-in the ring (approx. 2 hours).
- that the operational pressure and power consumption are correct.
- tliat on the magnetic coupling pumps, slip does not occur (no flow), and that the
temperature rise does not exceed
30°C.
8.
MAJNTENANa AND OPERATION
Opdg conditions under section 7 should be checked regularly.
8.1
LUBRICATION ROT& pumps in configoration M (e.g. HD41ER-IM22B) demand external lubrication of the
slide bearings. The intervals of re-lubric+ion and the type of lubricant are dependent on the
operating conditions;
ask the
mpplier for particulars.
Packing cord
as shaft seal demands current adjustment to ensure correct leakage at the stuffing
box.
Dependent on
RPM and viscosity the
stu£6ng box must leak 10-100 drops a minute to remove
the friction heat genergted between shaft and packing cord In the event of insufficient leakage
the heat generation will cause bardend packing rings and increased wear on the shaft.
Systems of sealing liquid in connection with double mechanical seals (configuration MM) must
be checked regularly to ensure
- that the liquid level in the sealing liquid container is coned
- that the concentration of the pumped medium in the sealing liquid does not overstep the
permissible quantity.

101. - that the circulation of the sealing liquid between container and s-g box is in
order.
- that in the case of "back to back" (configuration h4MP) the pressure of the sealing liquid
is higher than that of the pumped medium on the primary shaft seal.
8.4 DRY RUNNING
The slide bearings and the shaft seal of the ROTAN pump are usually lubricated by the pumped
liquid, and that
is why dry
runuing must not occur.
The lubricating properties of the pumped
liquid decide how long the pump may run without
liquid during priming and draining of the system.
9. REPAIR AND INSPECTION
A
Before attempting
any work on the pump ensure that it cannot be started
accidently or unintentionally.
A The system mast be completely de-pressurized and drained for liquid
The service engineer mast know which .liquid has been pnmped as well as which
a precautions he must take when handling the liquid in qnestion.
In connection with the servicing of magnetically. coupled pumps it should be
A. considered that the magnetic parts can cause damage to pacemakers, credit cards,
floppy disks, compaters, and watches.
A All precautionary measures, such as coupling gnards, pressure relief devices, and
insolation for wiring, mast be in place before the pump onit is restarted.
Pump construction appears in subsection 11.2 sectional drawings.
9.1 DWG THE PUMP
-. When the pipe work has been drained, some liquid will remain at the bottom of the pump and in
. . themffhgbox.
The pump can usually be drained by dismantling
the
kont cover or by placing thepup with the
suction/discharge ports upside down
and rotating the shaft.
However, it
can be
difficult for very viscous liquids to pass fiom the stu&g box and the
chamber between rotor
and
rear cover on to the pump casing; in such cases the stn£6ng box and
the rear cover are fitted with draining devices.
On ED pumps the liquid in the canister is removed through the plug (item MB).
Where toxic liqmds are pnmped, precautions should be taken before dismantling,
e.g. circulating neutralising liquids in the pump or using safety clothes and a
breathing mask.

102. 9.2 PUMP PARTS
The rotor, idler, pump casing, front cover and idler bearing can be inspected merely by removing
the front cover. There
is no need to remove the
pump from the installation.
Place the idler so that the smaller root diameter faces the front cover.
The front cover should be placed so that the crescent
is at the bottom of the pump.
The replacement idler pin
is secured by an adhesive to ensure tightness.
93 MECHANICAL SEAL
Before replacing the mechanical seal and prior to dismantling, the position of the rotating parts
on the shaft should be
measured and noted so that the new seal can be fitted correctly.
9.4
SOFT SEAL
To replace the above, the packing gland is dismantled, and the packing rings are removed with an
emor. New packing rings can be obtained already formed or they can be produced in the
following way:
Packing cord of the corm3 size must be wound round the shaft a number of times appropriate to
the number of packing rings and cut through along the shaft
with a sharp
Me. The packing
rhgs must be placed
in the
stu£6ng box with the slits diametrically opposite and pressed together
using the packing gland. See section 8.2 regarding adjustment
95 fxmm'E BEARINGS
The sleeve bearings must be lubricated when assembling, as they will not withstand dry
operation The lubricating groove, if any, in the idler pin should face the crescent The
lubricating groove
in the
main bearing should be turned upside down.
9.6 FLEXlBLE COUPLING
The HD, CD, PD, and ED pumps are coupled to the motor by means of a flexible coupling. The
alignment between the pump and motor must be checked by means of a straight edge over the
coupling halves
at 2 or 3 points on the coupling. Any
misalignment, will appear as a gap between
the straight edge and the coupling flange. A feeler gauge must be used to check that the gap is
constant all the way around the coupling. Permissible clearances for eccentricity qd parallelism
appear hm the supplier's instructions. For correct aligoment of the motor and pamp suitable
shims must be fitted
between the base of the pump and motor
amj the base plate. Inaccarate
alignment of the pump and motor will result in increased wear on the coupling elements.
9.7 LOCKING THE PUMP SHAFT
On disassembly/assembly it may be necessary to block the pump shaft. This is done by means of
a piece of wood or soft
metal placed between the teeth of the rotor through one branch of the Pump.

103. 9.8 ADJUS- OF AXIAL CTEARAANCE
The axial clearance is checked with a feeler gauge between rotorlidler and front cover. Access is
gained through one of the connection branches of the pump. Setting dimensions are shown in
sub-section 5.6.
I€ the pump is in sin& the following method of adjusting the axial clearance can be used, a feeler
gauge
is not necessary. Adjust the pump shaft so that the rotor touches the kont cover, and then
adjust the clearance between the
rotor/idler and kont cover using the adjusting screws
in
accordance with the following table:
Angle change
in0 =
Axial
clearancex 360
pitch
.. . .~. -. Regarding types HD, CD, and PD the clearance is adjusted by means of the b-g covers, items
. ..
CS and CR. Ensure that the screws, item CT, are tightened crosssvise so that the bearing will be
ptished squarely into the hoGing.
IDLER
The axial clearance of the GP pump is adjusted by means of the sleeve coupling, iitem DB,
between pump and motor shaft by
means of the adjusting screws, items
KX and W, which are
adjusted crosswise.
For adjustment of the axial clearance 'of the
ED pump the
fimt cover is displaced axially by
means of the screws, items E and NM. It is recommended that the clearance is checked at a
minkm of
3 points to ensure that the
fiont cover is parallel to the rotor.
After the adjustment is made, check that the pump shaft rotates easily and regularly.
9.9 ED PUMPS IN PARTICTIJAR
-
Thread
Pitch
The separation of the pump end (the screw joint, item
ME) should be done with great care as the
magnets
in the external magnetic rotor (item
MM) are easily damaged by scratches.
M8
125
The pump is provided with two threaded holes and two clearance holes in the lower part of the
rear cover (item BA) and the coupling housing (item CQ) respectively. By means of two
threaded bars the pump and the coupling part
can thus be pressed from each other, the foot of the
pump. casing being fixed to the base, and the foot of the coupling housing sliding on the base,
guided by the threaded bars. The coupling housing is pressed as far back'that the outer magnet
(item
IvlIvI) is completely free of the canister (item MJ). The same procedure is followed during
assembly.
M5
0,8
Alternatively disassembly/assembly can be done by using a block and tackle. The pump must be
mounted vertically on its end and the coupling part lifted using an eye bolt
in the shaft end.

104. Never put you fingers between the coupling part and the pump part during the
embl because, magnets will draw the parts together with mforce.
hitially the front cover is set to a distance of 2 mm fiom the pump casing to allow a clearance
between rotor and front cover during the assembly.
The torque of tightening for the bolt, itemMP, fixing the shaft
in the main bearing,
is:
- 10 Nm for coupling type A.
30 Nm for coupling types G, H, I; Check that the disc spring, item NG, is correctly
turned.
Take care that the magnetic parts do not pick up metallic shavings.
9.10 GP PUMPS IN PARTICULAR
The flanges motor of the GP pump must be provided with a- locked bearing at the drive end to
ensure
that the axial clearance of the pump is kept within the permissible limit
The
HD and CD pumps for pumping chocolate (re. s&g box see section 11.2) have been
designed so that the
main bearing (item
BC) is removed from the shaft seal housing along with
the pacldng gland (item BB). Then the packing gland is separated in two parts and'removed,
whereupon the
main
beadng can be pulled back on the shaft. Now there is ke access to pulling
out the packing rings by means of
a
packing extractor, and to fit new rings in the shaft seal
housing.

2.2 TECHNTCAL DESCRIPTION
The noise level indicated is the airborne noise inchlding the motor. The noise depends on the motor type
supplied, as the noise fiom the pump can be calculated as the noise level of the motor + 2dB(A). The
noise level
is for pumps with electric motors.
The capacity of the pump appears
hm the
name plate on the pump. If the pump has
been'delivered
without motor, the pump capacity is to
be indicated on the plate when mounting the motor.
The permissible loads on the flanges appear from the
following.table. The values apply to standard
pumps
in bronze
@g5) and cast iron (GG20). As to pumps in SG iron (GGG40) the values are to be
increased by factor 1.5.

117. In connection with the permissible loads on the flanges the following is to be observed:
where
index
"calc" are the values calculated by the user.
At the same time none of the forces or moments may exceed the indicated figure multiplied by 1.4.

If it is necessary to use tools for assembling, then protect the sliding surface of the seat to prevent it fiom
beiig scratched or cut. Lubricate the inner diameter of the slide ring rubber bellows with soapy water
and push it over the shaft. The use of a fitting bush as shown on the assembly drawing is recommended
to avoid
that the rubber bellows is cut.
Push the slide ring over the shaft
with the hand. If the rubber bellows is tight, use a fitting tool and take
care that the slide ring is not damaged. If the carbon ring is not
&ed, it is important to check that it is
fitted correctly, ie. the chamferedhpped side is to face the seat. The carbon ring can be held by a little
grease.
When using soapy water on the

held with a little grease. However, check the material of the O-ring fist. As standard the katerial is
nitrile, but it might be EPDM which will be damaged by mineral grease. Use soft soap or silicone grease
for EPDM. Fd and fasten bearing housing and shaft seal cover. Screw the pointed screw (86) back into
the shaft seal cover before tightening.
Insert the copper pipe (58).
When the pump has been assembled, check that the shaft rotates
fieely.

122. 6.8 FTIWNG COWLING
Fit the flexile coupling (74) to the spacer (72) by means of the Allen screws (76) which are tightened up
with torque according to the table below. Check that the aluminum insert in the mbber part does not
rotate during tighteniug as it may damage the coupling. To prevent this, apply a little grease to the bolts
under the bolt head. The Allen screws
(76) can be used again and up to 3 times before they are to be
replaced by new
on@ bolts to secure the locking function Do not use Loctite as it will damage the
rubber element.

123. 7. FROST PROTECTION
Pumps that are not in operation during fkost periods are to be drained to avoid kost damage. Remove
the plug
(3) at the
bottom to empty the pump. Alternatively, it is possible to use anti-fieeze liquids in
normal constructions.
8. DISMANTLING
A
Before dismantling the pump make sure that it has stopped. Empty the pump of liquid before
it is dismantled fkom the piping system. If the pump has been pumping dangerous
liquids you
are to be aware of this and take the necessary safety measures.
If the pump has been pumping hot liquids, take great care that it is drained before it is
removed
from the piping system
9. START-UP
a
A centrifugal pump will not function until it has been filled with liquid between the foot valve
and somewhat above
the
impeller of the pump.
The liquid also serves as coolant for the
shaft
seaL In order to protect the shaft seal the pump
must not run dry.
A'ITENTION I
For safety reasons the pump is only allowed to operate against closed suction and discharge valves for a
short
time
(max. 5- 10 minutes and at a max. temperature of 130°C). Otherwise there is a risk of damage
to the pump
and, at worst, of a steam explosion.
If the pump is not manually obsesved, the installationof
a safety
device is recommended. . .
9.1 STARTING
Before starting the pump check that:
- the shaft rotates keely without jarring sounds.
- the pump casing and the suction line are filled with liquid.
Start the pump for a moment to check the direction of rotation. If the direction is correct (ie. in the
direction of the arrow) the pump may be
started.
10. SYSTEM BALANCING
It is often
di£Ecult to calculate a manometric delivery head in advance. It is, however, decisively
important to the quantityof liquid delivered.
A considerably smaller delivery head than expected
will increase the quantity of liquid delivered, causing
increased power consuraption and perhaps cavitation
in pump and piping. In the pump the impeller may
show signs of heavy erosion caused by cavitation (corrosion) which may at
times
render anirnpeller un6t
for use in a very short time. Not unusually do similar erosions occur in pipe bends and valves elsewhere
in the piping system.
Therefore, after start-up, it
is necessary to check either the quantity of liquid delivered or the power

124. consumption of the pump e.g. by measuring the current intensity of the connected motor. Together with
a reading of the differential pressure the quantity of water delivered can be determined against the
characteristics of the pump.
Should the pump not function as intended, please proceed according to the fault-hdhg list. Bear
in
mind, though, that the pump was
carefully checked and tested at the factory and that the majority of
faults stem 6rom the piping system.

125. ll. INSPECTION AND MAINTENANCE
Inspect the shaft seal for leaks at regular intervals.
- Before inspection of a pump without guard check that the pump cannot be started
' ' " any.
- The system is to be without pressure and drained of liquid.
- The repairman must be familiar with the type of liquid which has been pumped as well as the
safety
measures he is to take when handling the liquid
11.1 DRAINING THE PUMP
When the piping systemhas been drained, note that there is st3l liquid in the pump. Remove the hquidby
dismantling the pipe plug (3) at the bottom of the pump.

146. 5.3.- Pipework Unions,
Straln on the pump collars can cause misalignment of the
flanges. To reduce strain the Ranges must be parallel and
concentric. The bolts or studs used to
fix the flanges
must
pass freely through the holes drilled in them. Do not forget to
place a seal or gasket between the parts of the joint.
NARNlNG DO not use lhe pump itself as a slruclurai member ol +' 1 e nstaliation. The inlet and ouliet pipes should no1 place any
slrain on the pump necks above the maximum limils. Use
independent braces to hold the weight and the strain of the
plpework, Pay altention to the direction of flow indicated in the
diagrams.
The diametem of the pipes, valves and accessories must be
calculated on the basis of the frlction losses planned for the
Installation such that the fiow rates are:
-Velocity in outlet plpe:
2 to 3
mlsec
-Velocity In inlet plpe:
1 to 2

IN THE INLET PIPE. It Is advlsable to use a coarse filter in
the
Inlet
plpe to avold the pump drawing In lumps of dirt and debris
lamer than the permitted slze. Elbows and sharp curves In the
plpework should be avolded, as should fitUngs that produce

or concentric. Fit a gate valve for isolation during
maintenance.
5.4.- Auxiliary fittings.
Except for th external elechical and pipework connections the
unit
is normally supplied assembled and ready for immediate
use.
The cooling of the mechanical seal or
packing gland Is
performed by the internal recirculation of the pumped liquid
(Plan AP.-01). Follow the detailed insbumons in the annex to
this manual Wenever It Is necessary to attach the auxiliary
fittings used by these devices,
