Centrifugal pumps

• In this part of the lesson we will take a closer look at Centrifugal pumps

Centrifugal pumps - theory and characteristics

• A centrifugal pump can be further defined as a machine which uses several energy transformations in order to increase the pressure of a liquid. The energy input into the pump is typically the fuel source energy used to power the driver.

Centrifugal pumps - theory and characteristics

• Energy input
• Most commonly, this is electricity used to power an electric motor.
• Alternative forms of energy used to power the driver include high-pressure steam used to drive a steam turbine.
• Fuel oil used to power a diesel engine.
• High-pressure hydraulic fluid used to power a hydraulic motor.
• Compressed air used to drive an air motor.
• Regardless of the driver type for a centrifugal pump, the input energy is converted in the driver to a rotating mechanical energy, consisting of the driver output shaft, operating at a certain speed, and transmitting a certain torque, or horsepower.
