Difference Between Centrifugal pump and Reciprocating pump [With PDF]

What is Centrifugal pump?

The hydraulic machine which converts the mechanical energy into hydraulic energy is called Pumps. The hydraulic energy is in the form of pressure energy. If the mechanical energy is converted into pressure energy by means of a centrifugal force acting on the fluid, the hydraulic machine is called a centrifugal pump.

Main Parts of Centrifugal Pump:

  • Impeller
  • Casing
  • Suction pipe with a foot valve
  • strainer and
  • Delivery pipe

You can read Centrifugal Pump in detail.

What is Reciprocating pump:

It is a hydraulic machine that converts mechanical energy into hydraulic energy. This is a positive displacement pump. Here a certain volume of liquid is collected in the enclosed volume and is discharged using pressure to the required application.

Reciprocating pumps are more suitable for low volumes of flow at high pressures.
