Centrifugal Pumps in Oil and Gas

Centrifugal Pumps in Oil and Gas

Pumps are used to transfer non-compressible fluid from one place to another. Process industries, where almost all process confined in pipes cannot run without pumps.

By definition , Pump is a mechanical machine that transfer the fluids by converting the mechanical energy into the pressure energy . This mechanical energy can be sourced from a prime mover i.e. electric motor or steam generator . 

The types of pumps used in Oil and Gas industry are:-

  1. Centrifugal Pump.
  2. Reciprocating Plunger Pump
  3. Metering Pump
  4. Gear Pump
  5. Diaphragm Pump
  6. Progressive cavity pump

Out of this list , centrifugal pumps are widely used in Oil and gas industry. Centrifugal pump uses centrifugal force to generate pressure energy and then transfer of fluid. Hence called centrifugal pump. 

For an engineering student , pump has following component:-

  1. Casing
  2. Impeller

  1. Casing
  2. Impeller
  3. Motor
  4. Mechanical Seal
  5. Shaft
  6. Coupling
  7. Bearing
