1. Working of reciprocating pump and its classification by mayulika timungpi rollno . Cve /23/32

2. Introduction A reciprocating pump is a positive displacement It uses a piston or plunger to move fluid through a cylindrical Commonly used for high pressure and low flow application main component Cylinder Piston/ plunger Section and delivery valves Crank and connecting rod Suction and delivery pipes

3. Working principle Base on positive displacement During suction stroke, the suction move to Create a vacuum, drawing fluid in. During delivery stroke, the piston pushes fluid out through delivery valve. Valves ensure one- direction flow suction stroke: Piston move away from cylinder head Volume inside the cylinder increase Pressure drops below atmospheric Fluid enter through suction valve

4. Classification of reciprocating pumps 1. Base on cylinder Single acting reciprocating pump Double acting reciprocating pump 2. Base on numbers of cylinder Single cylinder Multi cylinder (duplex, triplex) 3. Base on orientation Horizontal Vertical

5. Differences on single and double acting reciprocating pump

6. Application Oil and gas industries Chemical processing Water supply in rural areas Hydraulic system

7. Advantages and limitations Advantages High pressure Accurate flow limitations Low flow rate High maintenance

8. Conclusion Reciprocating pump are vital for high pressure application Understanding their classification help in proper selection Essential in many industrial system
