The PGF3-3X/032RE07VE4 belongs to the PGF Internal Gear Pumps series from Bosch Rexroth and serves as a fixed-displacement pump for hydraulic automation circuits. It displaces 32.5 cm³ of fluid per revolution so flow remains proportional to speed, and it turns clockwise to match right-hand drive trains. A minimum speed of 500 rpm maintains internal lubrication, while a maximum speed of 3000 rpm defines the safe upper limit for continuous duty. When driven at 1450 rpm the pump delivers a nominal flow of 47.1 L/min, supporting medium-size actuator groups. The 25 mm shaft couples to motors through a standard key and accepts up to 230 Nm of drive torque, preventing overload at high pressure. Installation uses an ISO 3019-2 100B4SW four-hole flange so the housing aligns quickly with common power unit plates.
An ISO 4406 (c) 20/18/15 cleanliness class is required to protect the gear set from abrasive wear, and a starting viscosity limit of 2000 mm²/s allows cold-oil startups without seizing. The pump sustains 210 bar as its continuous outlet pressure for normal operation and tolerates 250 bar intermittently to absorb short pressure spikes. A suction port sized SAE 1 1/4 provides low restriction on the inlet side, while the pressure port sized SAE 3/4 matches typical high-pressure lines. The assembled unit weighs 4.5 kg, allowing a single technician to mount it without lifting equipment.
