An impeller is a rotating component of a centrifugal pump, magnetic drive pump, chemical pump, or sealless pump and is typically made of iron, bronze, brass, steel, aluminum, titanium, or plastic. An impeller transfers energy from the motor which drives the pump to the fluid being that is being pumped, by accelerating that fluid outwards from the center of rotation.
The velocity gained by the impeller converts into pressure as the outward movement of the fluid is confined by the pump casing. Impellers are typically short cylinders that have an open inlet to accept the incoming fluid and vanes to push the fluid radially and a bore to accept a drive-shaft.
