* Reciprocating pump is a device which converts the mechanical energy into hydraulic energy by sucking the liquid into a cylinder.

* In this pump, a piston is reciprocating, which uses thrust on the liquid and increases its hydraulic energy.

Reciprocating pump is also known a called a positive displacement pump. Because it discharges a definite quantity of liquid. It is often used where a small quantity of liquid is to handled and where delivery pressure is quite large.

Parts of Reciprocating Pump

The following are the main parts of the reciprocating pump.

1.     Cylinder

2.     Suction Pipe

3.     Delivery Pipe

4.     Suction valve

5.     Delivery valve

6.     Air vessels

2. Double Acting Reciprocating Pump

In this, the water is acting on both sides of the piston as shown in the figure.
