Parker Aerospace's engine feed ejector pumps are hydro-mechanical jet pumps, with no moving parts. The pumps independently supply fuel to their respective engines using the motive flow supplied by the engine
The engine feed ejector pumps are hydro-mechanical jet pumps with no moving parts, and are comprised of an aluminum-alloy housing, nozzle, inlet/outlet, and a filter assembly inlet screen that is constructed of stainless steel. The engine feed ejector pumps provide a reliable, low weight, cost-efficient capability to supply fuel continuously to the engines.
Engine feed ejector pumps are the primary fuel pumps for the engines, and under normal conditions, supply fuel independently to their respective engines using motive flow supplied by the engine. The ejector pumps are jet pumps that draw fuel from the collector bays in each wing, when fed with the high pressure motive flow from the engines. The ejector pumps have a screen to preclude the ingestion of foreign objects.
APPLICATIONS: Commercial aircraft
FEATURES AND ATTRIBUTES:
Parker’s Engine Feed Ejector Pumps have a corrosion resistant, lightweight construction that weighs only 1.4 lb. The ejector pumps share a design and fielded service legacy of similar, reliable Parker fuel ejector pumps that goes back decades, with a guaranteed mean time between failure (MTBF) of 1,287,000 flight hours. The engine feed ejector pumps are certified for electrostatic discharge and conducted current lightning strikes by virtue of their construction and installation in the aircraft.
The ejector pumps are compatible with all standard, available kerosene aviation fuels including Jet A, Jet A-1, JP-5, JP-8, and TS-1. The engine feed ejector pumps are designed to operate with a nominal 16 gpm motive flow that produces a nominal 81 gpm at the outlet, at operating fuel pressures between 0 and 500 psig at the nozzle inlet, and between 0 and 50 psig at the outlet. Operational fuel temperatures can range between -58 degrees F and +131 degrees F, and with ambient operating temperatures between -67 degrees F and +185 degrees F.
