Quality Aircraft Accessories is a distributor for new Weldon aircraft fuel pumps. By closing this window you acknowledge that your experience on this website may be degraded. However, the constant volume of a vane pump can be excessive. Add to wishlist. A fuel pump is driven by the rotation of the aircraft engine. Close . Some centrifugal fuel pumps operate at more than one speed, as selected by the pilot, depending on the phase of aircraft operation. As the plunger rises, it pushes fuel in chamber D out the pump outlet port. An inlet port is located where the vanes create an increasing volume space, and fuel is drawn into the pump. Showing 1–20 of 152 results. Home Shop Aircraft Fuel Pumps. Fuel tanks with in-tank fuel pumps, such as centrifugal pumps, are constructed to maintain a fuel supply to the pump inlet at all times. Did you know that your internet browser is out of date? Quick Shop. The whole idea behind a fuel pump is to either get fuel to the engine or transfer fuel among tanks in the airplane. Any fuel in chamber C is forced through the small check valve in the center of the plunger and into chamber D. When positioned between the solenoid, the plunger is far enough away from the magnet that it no longer attracts it, and the pivot allows the contacts to open. As with all vane pumps, an eccentric rotor is driven inside a cylinder. Dukes Fuel Pump Overhaul 1184-00-1 … Delete. It is electric motor driven and most frequently is submerged in the fuel tank or located just outside of the bottom of the tank with the inlet of the pump extending into the tank. Their main another or from engine back to tanks. Fuel pumps are used to supply fuel through the system. Quick Shop. The single-acting pulsating electric fuel pump responds to the pressure of the fuel at its outlet. Slots on the rotor allow vanes to slide in and out and be held against the cylinder wall by a central floating spacer pin. You will be redirected to our US homepage. Show sidebar. $13.80. Quick Shop. Box 5792 Phone:+61 7 4155 1778 Bundaberg West Fax:+61 7 4155 2669 Queensland, Web: www.jabiru.net.au Australia. A bypass valve may be installed in the fuel feed system to allow the engine-driven pump to pull fuel from the tank if the boost pump is not operating. Aircraft Parts, Engine Parts, Fuel Pumps, Tempest 103396-01 TEMPEST O/H FL PUMP. Item Qualifies for Free Ground Freight (48 States) on Orders Over $350 . The pulsating electric pump uses a plunger to draw fuel in and push fuel out of the pump. Some aircraft use ejector pumps to help ensure that liquid fuel is always at the inlet of the pump. AeroControlex has extensive experience in the design and manufacture of aircraft fuel pumps for transfer, jettison and boost applications. Uses a rotor which turns the vanes in the cylinder and these vanes act to push fuel through the system. A diaphragm between the chamber D fuel and an airspace at the top of the pump dampens the output fuel pulses. View Catalog. Also as the plunger rises, it draws fuel into chamber C and through the check valve into chamber C. As the plunger rises, the magnet is attracted to it and the upward motion closes the points.

If you can’t transfer fuel among tanks in your airplane and it has a high wing and a carbureted engine, there’s no fuel pump—gravity gets the fuel to the engine. 200F Series. Centrifugal fuel pumps located in fuel tanks ensure positive pressure throughout the fuel system regardless of temperature, altitude, or flight attitude thus preventing vapor lock. It is usually used in the same manner as a centrifugal fuel pump on larger aircraft, except it is located downstream of the fuel tank outlets. Airborne Fuel Pump Overhaul 1B5-6 $ 996.32. It is a device used to distribute aviation fuel. The fuel is directed through a venturi that is part of the ejector. 2020 to 2027. During normal operation the main fuel pump, which is mechanically driven off the engine accessory drive, is sufficient to deliver fuel at the required pressure and flowrate. As the fuel rushes through the venturi, low pressure is formed. $1414.00. It is powered by a solenoid that alternates between being energized and de-energized, which moves the plunger back and forth in a pulsating motion. If the pump is mounted outside the tank, a pump removal valve is typically installed so the pump can be removed without draining the fuel tank. Item: AE AF15473 Price: $399.00 .
