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 series of gear fuel pumps contain a centrifugal boost stage, fuel fi lter, and gear stage.

2 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 fuel GEAR PUMP 1000 PSIG @ 6000 RPM704300, 708300, 708400, 708600, 714900 APPLICATIONS CFM56-2, CFM56-2A, CFM 56-2B CFM56-3, CFM56-3B, CFM56-3C CFM56-5, CFM56-5A, CFM56-5B, CFM56-5C3 Eaton CORPORATION Aerospace TF600-52 November 2008 Model shown 708600 PERFORMANCE SPECIFICATIONS OPERATING CHARACTERISTICSS peed6000 RPMI nlet Pressure30 psig (138 kPag)Boost Stage Pressure Rise140 psid (965 kPag)Discharge Pressure1000 psig (6895 kPag) fuel Flow Rate58 gpm (220l/min)CRANKING CHARACTERISTICSS peed 625 RPMI nlet Pressure30 psig (207 kPag)Discharge Pressure 305 psig (2103 kPag) fuel Flow gpm ( )RotationClockwiseWeight 44 pounds ( kg)Model shown 708600 Eaton s 724400 model gear fuel pump contains a centrifugal boost stage, fuel fi lter and gear stage.

4 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 fuel GEAR PUMP 1145 PSIG @ 6250 RPM828300 APPLICATIONS CFM56-7B5 Eaton CORPORATION Aerospace TF600-52 November 2008 Model shown 828300 PERFORMANCE SPECIFICATIONS OPERATING CHARACTERISTICSS peed6250 RPMI nlet Pressure30 psig (207 kPag)Boost Stage Pressure Rise110 psid (758 kPad)Discharge Pressure1145 psig (7895 kPag) fuel Flow Rate65 gpm (246 l/min)CRANKING CHARACTERISTICSS peed (RPM)625 RPMI nlet Pressure30 psig (207 kPag)Discharge Pressure 305 psig (2100 kPag) fuel gpm ( l/min)RotationClockwiseWeight pounds (22 kg)Model shown 828300 Eaton s 828500 model pump inlet feeds into the centrifugal boost stage, which raises the pressure of the fuel .

5 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.
