Parker Aerospace fuel transfer pumps main pumping element use a centrifugal impeller driven by a three phase constant frequency or variable frequency induction motor. Input frequency varies between 360 and 800 Hz. The canister is installed on the wet side of the spar with the pump element installed into the canister from the dry side.  This allows the element that contains the motor and bearings to be replaced without draining the fuel tank.

Ranging from fuel boost and transfer pumps to hydraulic brake and actuation pumps, potable water pumps, recirculation pumps, and APU fuel feed pumps, Parker Aerospace’s pumps add real power to both military and commercial aircraft. Our brushless, electric DC motor-driven pumps with sensorless or sensor-based electronic controls offer powerful advantages.
