For over 50 years Eaton has been the leading manufacturer of highly reliable main engine fuel pumps. These main engine fuel pumps are highly designed, precision mechanical pumps, mounted to the aircraft’s engines that maintain the fl ow of fuel to the engine at a precise rate and pressure. Eaton’s main engine fuel pumps are installed on 70% of the commercial jet engines currently fl ying today. They are utilized on military, commercial, regional and business aircraft engines worldwide.

This series of gear fuel pumps contain a centrifugal boost stage, fuel fi lter, and gear stage. Fuel supplied by the aircraft boost pump enters the boost stage, which increases pressure 125 psi (862 kPa). This pressure forces heated and fi ltered fuel through internal passages to the gear stage. Fuel is directed to the fuel control where it is re-fi ltered and returned to the fuel control.

Eaton’s 724400 model gear fuel pump contains a centrifugal boost stage, fuel fi lter and gear stage. Fuel supplied by the aircraft boost pump enters the boost stage, which increases pressure. This pressure forces heated and fi ltered fuel through internal passages to the gear stage. Fuel is directed to the fuel control system where it is re-fi ltered and returned to the aircraft pump.

Fuel supplied by the aircraft boost pump enters the fuel pump boost stage, which increases pressure. Boost stage output fl ows through a cooler, main heat exchanger, and the pump fuel fi lter and then into the high-pressure gear stage. Bypass fl ow from the fuel control joins the boost stage discharge and re-enters the gear stage. A high-pressure relief valve permits the entire pump discharge fl ow to return to the gear stage inlet. This limits gear stage pressure.

Eaton’s 828500 model pump inlet feeds into the centrifugal boost stage, which raises the pressure of the fuel. Discharge from the boost stage mixes with returned fuel from the fuel control and is fi ltered before entering the high-pressure gear stage, which forces the fuel through heat exchangers. The fuel re-enters the pump through the main fuel fi lter and servo wash fuel fi lter assemblies and into the hydro-mechanical unit (HMU). The HMU measures fuel fl ow and returns unused fuel and servo discharge to the pump bypass return port.

Fuel enters the pump at a pres-sure of approximately 20 psi (138 kPa) from the air-craft booster pump. The centrif-ugal boost stage raises the fuel pressure and forces heated and fi ltered fuel through the gear housing to the high-pressure gear stage. The high-pressure gear stage discharges fuel to the fuel monitoring unit (FMU). Fuel is ported back to the pump through the heat exchanger, re-fi ltered and returned to the FMU.

A single element gear stage paired with a high-speed cen-trifugal boost with relief valve limits the pressure rise across the gear stage. A replaceable micronic barrier fi lter element is located between the discharge of the centrifugal stage and the inlet of the gear stage. The removable pump cover houses a plug-type valve for sump and center fi lter draining. Outlet and return ports are provided between the boost stage discharge and the fi lter inlet for installation of an external fuel heater.
