The PGP3-3X/020RE20VE4 pump is manufactured by Bosch Rexroth for the PGH High Pressure Gear Pumps series. It supplies hydraulic fluid to automation circuits where stable displacement and compact size are required. A displacement of 20.6 cm³ per revolution defines the volume delivered each shaft turn, while a flow rate of 29.9 L per minute at 1450 rpm supports medium-duty actuators and valve groups. Clockwise shaft rotation matches standard motor couplings, and the minimum speed of 600 rpm sets the lowest allowable drive speed before volumetric loss becomes excessive. A 4-hole ISO 3019-2 mounting flange positions the unit accurately on pump housings, and the overall mass is limited to 4.3 kg to ease handling during service.
The pump sustains a continuous outlet pressure of 250 bar for normal duty cycles and tolerates intermittent peaks up to 315 bar to absorb short load spikes. FKM seal material provides resistance to hot oil and additive packages common in industrial hydraulic fluids. The pressure port uses a 35 mm bolt circle, a 12 mm bore, and an M6 thread cut 12 mm deep so high-pressure fittings remain secure under full load. On the suction side, a 55 mm bolt circle and a 20 mm bore reduce inlet restriction and help prevent cavitation at high speeds. Together these port dimensions, pressure ratings, and seal selection define a gear pump suited to tightly packaged yet demanding hydraulic automation tasks.
