• Takes energy from the flow turbine, hydraulic motor 

• Gives energy to the pumps and compressors

• Pumps are divided into roto dynamic or centrifugal pump move fluids with rotating vane.

• Positive displacement pump moves fluid strictly by precise machine displacement.

• This is are three basic concepts that are volute, casing and body or diffuser, impellers, driver motor.

• Consists of a series of blades attached at the centre of a shaft known as an impeller and rotated at high speed inside a casing.

• Fluid is fed in axially at the centre (eye) of the impeller & is thrown out in a roughly radial direction by the centrifugal action.
