PGF3-3X/040RJ07VU2

The PGF3-3X/040RJ07VU2 is supplied by Bosch Rexroth in the PGF Internal Gear Pumps series and delivers pressurized fluid for hydraulic automation loops that require steady flow and compact installation. Its displacement is 40.5 cm³ per revolution, which defines how much oil is moved each shaft turn and directly influences actuator speed. At a nominal flow of 58.7 L/min the unit can feed medium-size cylinders and motors without auxiliary boosting. The design allows operation from 500 rpm upward, so it can start circulating fluid at low engine idle in mobile machinery, while a 2500 rpm upper limit supports high-speed drives without cavitation. Rotation is fixed clockwise, simplifying coupling orientation when paired with standard right-hand prime movers. A continuous outlet pressure capability of 180 bar lets builders design circuits that run all day at moderate working loads, and a mass of 4.9 kg keeps the pump light enough for direct mounting on power take-offs. That attachment is achieved through an SAE two-hole flange per ISO 3019-1, making it interchangeable with a wide range of frame adapters.

The model tolerates short peaks to 210 bar, giving reserve pressure for momentary load surges such as cylinder end-stops. On the suction side it accepts absolute inlet pressures down to 0.6 bar, which permits moderate vacuum without risk of vapor pockets, while a 3 bar absolute ceiling prevents seal damage when the supply line is pressurized. Connection hardware is straightforward: the pressure port is sized for an SAE 3/4 fitting to match common 12.7 mm tube systems, and the suction port uses an SAE 1 1/4 interface for low restriction on the return to tank. A pilot diameter of 101.6 mm centers the housing in the mounting flange so radial runout remains minimal. Torque is transmitted through a 13-tooth, 16/32 DP, 30° involute spline, enabling secure engagement with standard splined shafts. Fluid compatibility is improved by an FKM seal set, which resists high temperature and many synthetic hydraulic oils, supporting long service life in demanding industrial environments.
