The PGF2-2X/011RJ20VU2 internal gear pump belongs to the PGF Internal Gear Pumps series and is manufactured by Bosch Rexroth. It supplies hydraulic circuits with a displacement of 11.0 cm³ per revolution and produces a flow of 16 L/min when driven at 1450 rpm under 10 bar discharge pressure. The pump is configured for clockwise rotation, aligning with right-hand drive shafts in typical power units. A 2-hole ISO 3019-1 (82-2) mounting flange and an 82.55 mm pilot diameter position the housing accurately on motor adapters. Fluid is drawn through a suction port with a 20 mm bore on a 40 mm pitch circle and exits through metric square flanges compliant with DIN 3901/3902, allowing straightforward pipe connections. The minimum permitted speed is 600 rpm, ensuring reliable lubrication of internal gear sets at low machine cycles.
The PGF2-2X/011RJ20VU2 operates continuously up to 210 bar and tolerates pressure peaks to 250 bar for short intervals, supporting actuators that experience transient load rises. Suction conditions must remain between 0.6 bar minimum and 3 bar maximum to prevent cavitation and seal stress. The drive end features a 9-tooth, 16/32 DP, 30° involute spline that mates with standardized couplings for torque transmission. A low rotating moment of inertia of 0.00012 kg·m² minimizes start-up load on prime movers and aids rapid deceleration during controlled stops. These characteristics, combined with the previously noted flow and mounting details, make the pump suitable for compact power packs where stable delivery, moderate pressure capability, and precise alignment are required.
