What is an Aircraft Hydraulic Pump?

Aircraft hydraulic pumps are used to operate several different types of aircraft equipment, including the brakes, retractable landing gear, propellers, wing flaps, and other systems. On smaller aircraft, the hydraulic system is usually pressurized by an electric hydraulic pump, while larger aircraft use an engine-driven hydraulic pump. A single aircraft may have multiple hydraulic pumps, sometimes even both an engine-driven and an electric pump in the same aircraft, controlling different systems.

The hydraulic pump does not generate pressure itself. The mechanical action of the pump moving within the canister creates a vacuum which pulls or pushes the hydraulic agent: like hydraulic oil or fuel. The hydraulic pump may hold system pressure at a constant high level or may hold low pressure until activated. Both types of hydraulic pump systems generally use a hydraulic actuator to convert the fluid pressure into a desired motion.
