An impeller is a rotating iron or steel disc with vanes in a centrifugal pump.

Impellers transfer energy from the motor that drives the pump to the fluid being pumped by accelerating the fluid radially outwards from the centre of rotation.

The velocity achieved by the impeller transfers into pressure when the outward movement of the fluid is confined by the pump casing. Impellers are available as vortex or channel impellers.
