The PGF1-2X/4 1RN01VM internal gear pump belongs to the PGF Internal Gear Pumps series from Bosch Rexroth and delivers hydraulic power for automation loops that require steady pressure and compact form factors. Its displacement is 4.1 cm³ per revolution, so each shaft turn moves a defined fluid volume for predictable circuit flow. The shaft is designed for clockwise rotation, matching right-hand drive layouts common in machine tools. When driven at 1450 rpm and 10 bar, the unit supplies up to 6.0 l/min, while the minimum admissible speed of 600 rpm maintains internal lubrication during slow-running cycles. Continuous duty is permitted to 210 bar, and brief overloads are tolerated to 250 bar. With a moment of inertia of 0.000021 kg·m², the rotor accelerates quickly, supporting responsive pressure control in servo-based systems.
BSP threaded ports according to ISO 228-1 size 01 simplify plumbing to standardized manifolds, and a 2-hole attachment pattern with a 32 mm pitch positions the pump directly on motor flanges or brackets. The shaft end uses a two-flat driver, allowing positive engagement with keyed couplings while resisting torsional slip under the 14 Nm maximum drive torque. Suction conditions are limited to 3 bar on the high side and 0.6 bar on the low side, ensuring that inlet seals remain intact during priming and low-pressure draws. Fluorocarbon rubber (FKM) seals provide chemical resistance for common hydraulic oils, and the complete assembly weighs 2.0 kg, easing installation in densely packed power packs.
