Are you looking for the Difference between Centrifugal pump and Reciprocating pump? So today we will study the difference between the centrifugal pump and the reciprocating pump. Here you will get the articles of Mechanical Engineering in brief with some key points and you will get to know an enormous amount of knowledge from It. So If you find this articles helpful, please let us know in the comment box, either if any correction required too, also let us know in the comment box.

Let’s have an overview of centrifugal and Reciprocating pump first. So,

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

Difference Between the Centrifugal pump and Reciprocating pump

Reciprocating pump:

    • A reciprocating pump is a hydraulic machine which converts the 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.
    • The reciprocating pump having two types: 1. Single-acting reciprocating pump and 2. Double acting reciprocating pump.

Main Parts or Component of Reciprocating Pump:

  • Suction Pipe
  • Suction Valve
  • Delivery Pipe
  • Delivery Valve
  • Cylinder
  • Piston and Piston Rod
  • Crank and Connecting Rod
  • Strainer
  • Air Vessel

Difference between Centrifugal pump and Reciprocating pump

Difference between Centrifugal pump and Reciprocating pump:

Sl.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 low or medium pressure head. But Reciprocating pump work at the High-pressure head.
3. Discharge Centrifugal pump, Discharge is High. But Here, Discharge is low.
4. Requires relief valve In Centrifugal pump there is not required relief valve. But here, it requires a relief valve.
5. Smooth or Pulsating flow This is having a smooth flow. Here, This is having a pulsating flow.
6. Delivery Variable Constant delivery.
7. Self-priming There is no any self-priming. Here, There is self-priming
8. Space considerations It requires less space whereas, The reciprocating pump requires more space.
9. Cost The initial cost is low. The initial cost is higher.
10. Power consumptions Here, 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 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.
