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:
- 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.
Difference Between Centrifugal pump and Reciprocating pump:
|Sr.No||Parameter||Centrifugal Pump||Reciprocating Pump|
|1.||Construction||This is simple in construction.||This is complicated in construction.|
|2.||Head or Pressure application||This work on low or medium pressure head.||Reciprocating pump work at the High-pressure head.|
|3.||Discharge||Discharge is High.||Discharge is low.|
|4.||Requires relief valve||In the Centrifugal pump, there is no requirement of relief valve.||It requires a relief valve.|
|5.||Smooth or Pulsating flow||It has a smooth flow.||It has a pulsating flow.|
|6.||Delivery||Variable delivery.||Constant delivery.|
|7.||Self-priming||There is no any self-priming.||There is self-priming|
|8.||Space considerations||It requires less space.||The reciprocating pump requires more space.|
|9.||Cost||The initial cost is low.||The initial cost is higher.|
|10.||Power consumptions||Power consumption is high.||But in the centrifugal pump, the power consumption is low.|
|11.||Maintenance||It requires lower maintenance.||It requires higher maintenance.|
|12.||Air vessel||Not required||Air vessel is required in the reciprocating pump.|
|13.||Fluid handling||Suitable for a wide range including clean, clear, abrasive fluids, dirty water, and oil.||Suitable for clean, clear and non-abrasive fluids.|
