What is a Rotodynamic Pump ?

A rotodynamic pump is a pump in which the impeller imparts kinetic energy to the fluid. The term Rotodynamic is a broad one encompassing all pumps with rotary impellers.

Centrifugal pumps are a type of rotodynamic pumps.  The impeller of the centrifugal pump draws in water from the suction and pushes the water radially giving kinetic energy to the liquid.

Apart from centrifugal pumps, axial flow pumps in which the water flows radially, parallel to the axis of the shaft, are also called rotor dynamic pump.
