PGF2-2X/013RE20VE4

The PGF2-2X/013RE20VE4 internal gear pump is part of the PGF Internal Gear Pumps series manufactured by Bosch Rexroth for hydraulic automation circuits that require steady fluid delivery. Its displacement is 13.3 cm³ per revolution, so each turn of the drive shaft moves a fixed fluid volume that supports predictable actuator motion. When operated at 10 bar and 1,450 rpm, it supplies a maximum flow of 19.3 l/min, giving systems a clear reference for sizing return lines and reservoirs. The pump tolerates a continuous operating pressure of 210 bar, which defines the everyday load limit for valves and hoses, while a short-term pressure peak of 250 bar covers brief shock events during rapid directional changes. A maximum input speed of 3,600 rpm lets designers pair the unit with high-speed electric motors, and a minimum speed of 600 rpm maintains internal lubrication to prevent wear during slow cycles. Clockwise rotation is required, so the drive motor and hose routing must follow this orientation.

An 80 mm centering diameter aligns the housing precisely in a gearbox or bracket to minimize radial stress on the shaft. The four-hole ISO 3019-2 80B4HW mounting flange fixes the pump securely to standard hydraulic power units, and the square flange line connections compliant with DIN 3901/3902 provide a consistent port interface for pressure and return pipes. A 20 mm shaft diameter matches common spline or key couplings, simplifying integration with existing motor adapters. The suction port bore is also 20 mm, ensuring the inlet can support the rated flow without excessive velocity or cavitation. A maximum drive torque of 140 Nm allows the shaft to transmit full load pressure without slipping, while a through-drive torque limit of 70 Nm lets an additional pump be piggy-backed without overstressing the gear set.
