PGH5-2X/080RE11VE4

The PGH5-2X/080RE11VE4 gear pump is built by Bosch Rexroth and belongs to the PGH High Pressure Gear Pumps series. It supplies hydraulic fluid to actuators and valves where precise high-pressure flow is needed in automated machinery. The pump withstands a continuous pressure of 315 bar, allowing stable service in heavy-duty circuits. A maximum operating pressure of 350 bar provides short-term reserve for pressure peaks during load changes. The displacement volume is 81.4 cm³ per revolution, so each shaft turn delivers a predictable fluid quantity for accurate volumetric control. Operation is possible from 200 to 3000 rpm, giving designers freedom to match pump speed to engine or motor drives. Clockwise rotation defines the correct drive orientation for aligning with standard power-train layouts. A shaft diameter of 40 mm transmits the required torque without excessive deflection, and the 12 mm key width secures the coupling against slip.

The acceptable fluid temperature range of −10 to +80 °C lets the pump work with mineral oils in both cold starts and warm running conditions. An inlet pressure window of 0.8 to 2 bar prevents cavitation at the suction side while avoiding seal stress at higher inlet pressures. The viscosity range of 10 to 300 mm²/s ensures the gear set maintains lubrication and volumetric efficiency across common hydraulic oil grades. A 4-hole ISO 3019-2 160B4SW mounting flange provides standardized attachment to power units and bell housings. The suction port is a 2 in SAE connection according to ISO 6162-1, giving low restriction entry for high flow rates. Discharge leaves through a 1 1/4 in SAE port per ISO 6162-2, matching common high-pressure hose assemblies. FKM seal material resists heat and oil additives, extending service life in continuous industrial duty.
