Casting Propeller & Impeller Pump

An impeller or impellor is a rotor used to increase the pressure and flow of a fluid. It is the opposite of a turbine, which extracts energy from, and reduces the pressure of, a flowing fluid. The velocity achieved by the impeller transfers into pressure when the outward movement of the fluid is confined by the pump casing. FHZL casting impeller for Andritz and many other plants.
