6. Single stage / Multi Stage
•Single stage
•Multistage
•Gland packing – graphite, cotton or
asbestos flax

7. Characteristics of centrifugal pump
•No flow – pressure is maximum
•Delivery valves opened - pressure
decreases
•Pumps speed increases – pressure to
increases
•Drive – IC engine
•Pump performance – suction lift

8. Pump performance
•Duty point – maximum quantity of water as
specific pressure.
•7 Kg/cm2 at 3 mt depth

9. Priming devices
•Reciprocating primer
•Exhaust ejector
•Rotary (sliding vanes)
•Rotary (water ring)

10. Reciprocating Primer
•It is small force pump which is driven the main pump
drive shaft. Usually arranged in pairs or single
position double acting pumps. RPM 1000 to 1500.
•Advantages:
•Simple to operate
•Highly efficient
•Positive in action
•Operates at low engine speed.
•Dis-advantages:
•Bulky
•No. of working parts liable to wear and tear.

11. Exhaust Ejector Primer
•It utilizes exhaust gas from engine which are
diverted through directed across the apparatus of a
tube connected to the impeller chamber. requires full
engine speed
•Advantages:
•Simple in operation
•Less subject to damage and mis-handling
Dis-advantages:
•Less efficient than reciprocating primers
•Acting back pressure on engine
