Control optionsPressure & Flow (Load Sense) CompensatorWarning:To loadTorque controlGageOutlet(Opt)GageInlet(Opt)InletBleed downThe pump will provide flow & pressure matching of pump outputto system load demand, maximizing efficiency and improvingload metering characteristics of any directional control valveinstalled between the pump and the load. Load sensing ensuresthat the pump always provides only the amount of flow neededby the load. The pump operating pressure adjusts to the loadpressure plus a pressure differential required for the load sensemargin. When the system is not demanding flow, the loadsense control will operate in low pressure zero flow, energysaving stand-by mode. The differential pressure is the differencebetween the pressure inlet and service port of a proportionallycontrolled directional valve, or a load sensing directional controlvalve. See the model code for differential pressure settings forload sensing. If the load pressure exceeds the system pressuresetting, the pressure compensator reduces pump displacement.The load sensing line must be as short as possible and canalso be used for remote pressure control or unloading of thepump pressure. For remote pressure control purposes, it isrecommended that you contact your Eaton Representative forthe correct configuration of the control.(Opt)Load SenseTypical operating curve1. When adjusting the pressure limiter, install a 0 to 350 bar(0 to 5000 psi) gage in the outlet gage port and limit thepressure setting to the continuous rated pressure for thepump displacement. It is possible to adjust the pressurecompensator beyond the rated pressure of the pump.Doing so, may void the warranty of the pump.2.

Control optionsTorque ControlThe Torque Control limits the torque input to the pumppreventing the engine from stalling while also optimizing the useof the engine power.When combined with Pressure Compensator Control and/orLoad Sense, it will allow the pump to remain inside the powerenvelope of the Pressure Flow curve. When the combination ofpump flow and outlet pressure moves outside the envelop thepump displacement will automatically be reduced.This maximum setting is easily calculated using thefollowing steps: Select the 620 pump displacement you intend to useIdentify the available engine horsepower (HP) and speed (rpm)Calculate the torque limit required by the system using theequations shownSelect the MAX torque setting from the table shownTorque (in-lbs) Horsepower (HP) x 63025 / Engine RPMTorque (Nm) Horsepower (KW) x 9550 / Engine RPMTo loadTorque nletBleed down(Opt)Load SenseTorque curve 620 74cc pressure Vs. torque at 2400RPMTorqueNm [lb-in]74ccABACADAE51 [450]62 [550]73 [650]85 [750] AFAGAHAJAKALAMANAP96 [850]107 [950]119 [1050]130 [1150]141 [1250]153 [1350]164 [1450]175 [1550]186 [1650] 74cc98ccARATAUAWAZBBBDBFBHBKBMBNBPBR198 [1750]209 [1850]220 [1950]243 [2150]266 [2350]288 [2550]311 [2750]333 [2950]356 [3150]379 [3350]401 [3550]286.5 [2536]184.4 [1632]303 [2682] 402000Flow (GPM)Torque (inch Lbs)50%75%90%of rated torque1500100030201050020%50%00050010001500 20002500 3000Pressure (PSI)35004000Torque curve 620 98cc pressure Vs. torque at 2200 RPM050075%90%of rated torque1000150020002500Pressure (PSI)30003500 4000(Torque curve 620 98cc pump) pressure Vs. flow curve at 2200 RPM35006020%300050%250075%90%of rated torque50Flow (GPM)Torque (inch Lbs)TorqueNm [lb-in]5020%2500200015001000403020105007 Pos#20,21CodeTorque curve 620 74cc pressure Vs. flow curve at 2400 RPM3000098cc05001000 1500 2000 2500 3000 3500 4000 4500Pressure (PSI)EATON 620 MOBILE PISTON PUMP CATALOG0020%50%500E-PUPI-TM017-E6 July 201875%90%of rated torque1000 1500 2000 2500 3000 3500 4000 4500Pressure (PSI)www.eaton.com

Control optionsElectronic Displacement Control (EDC)Pump displacement can be controlled infinitely, as per thecurrent signal provided to the solenoid control valve.The integrated pump control makes use of an external currentsignal to vary the pump displacement. This control has anproportional characteristic i.e. with increasing current signal,the displacement increases proportionately.This control is with manual override. Based on fail safe conditionthere are two types:Min type (EP): Return to min displacement in case of power loss.Max type (EPD): Return to max displacement in case of power lossWarning:1. When adjusting the pressure limiter, install a 0 to 350 bar(0 to 5000 psi) gage in the outlet gage port and limit thepressure setting to the continuous rated pressure for thepump displacement.

Control optionsEH Inverse Proportional Pressure Control (IPPC)The EH Inverse Proportional Pressure control allows for steplessvariation of the max pump output pressure, as per the currentsignal provided to the control valve solenoid.The integrated pump control makes use of an externalcurrent signal to vary the pump output pressureTo loadGage outletThis control has an inverse proportional characteristic i.e.with increasing current signal, the max output pressure isproportionately reducedWarning:1. When adjusting the pressure limiter, install a 0 to 350 bar(0 to 5000 psi) gage in the outlet gage port and limit thepressure setting to the continuous rated pressure for thepump displacement. It is possible to adjust the pressurecompensator beyond the rated pressure of the pump. Doingso, may void the warranty of the pump.2.
