Reciprocating Pump

The reciprocating pump is a positive displacement pump as it discharges a definite quantity of liquid during the displacement of its piston or plunger which executes a reciprocating motion in a closely fitting cylinder. It is best suited for less discharge and higher heads.

The following important points may be noted for the reciprocating pump:

(a) Discharge through a reciprocating pump,

Discharge through a reciprocating pump

(b) Power required to drive a reciprocating pump

 

(c) The difference between the theoretical discharge and the actual discharge is called the slip of the pump.

(d) The slip of a reciprocating pump is negative when the suction pipe is long and delivery pipe is short and the pump is running at high speeds.
