The main differences between Centrifugal Pump and Reciprocating Pump are the Centrifugal pump works low medium pressure head and Reciprocating Pump works high medium pressure head.

Before moving to further detailed explanation lets have some overview of Centrifugal and Reciprocating Pump.

Note: At the bottom of every article the PDF link is attached make sure if you want you can easily download.

So let’s start with the Centrifugal Pump,

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.

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.

Difference Between Centrifugal pump and Reciprocating pump:

Sl.NoParameterCentrifugal PumpReciprocating Pump
1.ConstructionThis is simple in construction.This is complicated in construction.
2.Head or Pressure applicationThis work low or medium pressure head.But Reciprocating pump work at the High-pressure head.
3.DischargeCentrifugal pump, Discharge is High.But Here, Discharge is low.
4.Requires relief valveIn the Centrifugal pump, there is not required relief valve.But here, it requires a relief valve.
5.Smooth or Pulsating flowThis is having a smooth flow.Here, This is having a pulsating flow.
6.DeliveryVariableConstant delivery.

and here are the other 7 points,

7.Self-primingThere is no any self-priming.Here, There is self-priming
8.Space considerationsIt requires less space whereas,The reciprocating pump requires more space.
9.CostThe initial cost is low.The initial cost is higher.
10.Power consumptionsHere, Power consumption is high.But in the centrifugal pump, the power consumption is low.
11.MaintenanceIt requires lower maintenance.It requires higher maintenance.
12.Air vesselNot required Air vessel required in the reciprocating pump.
13.Fluid handlingSuitable for a wide range including clean, clear, abrasive fluids, dirty water, and oil.Suitable for clean, clear and non-abrasive fluids.

So this our short presentation on the difference between Centrifugal and Reciprocating pump, I hope you like it if so, let me know your thoughts in the comment section.
