The PGF2-2X/022RJ20VU2 internal gear pump belongs to the PGF Internal Gear Pumps series from Bosch Rexroth. It displaces 22.0 cm³ per revolution, supplying hydraulic power for automation loops that require repeatable flow. Clockwise rotation matches common electric-motor drives, and the speed window from 600 to 3000 rpm lets builders tailor output to variable duty demands. At 1450 rpm it provides 31.9 L/min, supporting medium-flow actuators with stable delivery. Continuous outlet pressure is rated at 180 bar for normal operation, while intermittent peaks can reach 210 bar to handle brief load spikes. These values position the pump for clamping, steering, and feed circuits that must maintain consistent performance under changing loads.
The suction side tolerates 0.6 to 3 bar absolute, and fluid enters through a ×26, PC ×55 port so adequate inlet conditions are retained across diverse reservoir layouts. Discharge exits a ×12, PC ×35 pressure port that mates with standard fittings for quick line routing. An SAE 2-hole U2 mounting flange aligns the housing to motor adapters, and drive torque is transmitted by a SAE J498b 9T 16/32DP 30° spline shaft. FKM seals resist heat and oil aging when the pump runs on HL or HLP mineral oils defined in DIN 51524. Overall weight is 3.1 kg, allowing one-person handling during installation or maintenance.
