Apr 01 2018 · Reciprocating pump is a device which converts the mechanical energy into hy d raulic energy by sucking the liquid into a cylinder. In this pump a piston is reciprocating which use thrust on the liquid and increase its hydraulic energy. Reciprocating pump is also known a called a positive displacement pump. Because it discharges a definite quantity of liquid.

Chat OnlineHow to Start A Pump The Engineering Concepts
What is the Reciprocating pump start up procedure Pump Start-up Procedure. Line up the pump valves. Ensure that the drain valve is closed. Open the suction valve. Open the vent valve to bleed off gaseswhen liquid comes from the vent valveclose it again. (This is called Priming the pump ). Open the gland-seal valve (if fitted).
Chat OnlineWhy is priming necessary for centrifugal pump Arun Raina
Apr 29 2016 · In Centrifugal pumps we require priming while in the Reciprocating pumps when the piston or diaphragm moves backward the volume of cavity increases and pressure inside it drops this opens the inlet valve and liquid is taken in until the differential pressure between the supply side and the chamber is zero.

Difference between Centrifugal pump and Reciprocating pump. Centrifugal pump is a rotodynamic pump that uses kinetic energy to transfer fluid from low pressure to high pressure while the reciprocating pump uses a piston (suction and discharge stroke) to transfer fluid. Centrifugal pump is the most popular pump as compared to the reciprocating pump.
