The PGF3-3X/020RJ07VU2K pump is part of the PGF Internal Gear Pumps series from Bosch Rexroth and supplies hydraulic oil for automated actuation and power transfer. It is built for clockwise rotation, allowing direct coupling to prime movers that share the same rotation without additional idlers. A displacement of 20.6 cm³ per revolution sets the delivered volume per shaft turn for predictable circuit sizing. The unit starts delivering flow from a minimum speed of 500 rpm so low-speed drives can maintain lubrication and control. At 1450 rpm and 10 bar it reaches a flow of 29.9 L per minute, supporting medium-duty actuator groups. Continuous pressure capability reaches 210 bar, providing headroom for typical industrial lines, while a permitted pressure peak of 250 bar covers short load spikes during rapid directional changes.
Installation follows the SAE 2-hole mounting flange defined in ISO 3019-1 101-2, which matches common motor and adapter patterns. The pressure outlet uses an SAE 3/4 port and the suction side uses an SAE 1 1/4 port, simplifying hose selection and reducing restriction. A 13-tooth 16/32 DP 30° involute spline transfers torque to the shaft and mates with standard drive couplings. The shaft can accept up to 140 N·m of through-drive torque, enabling tandem arrangements where downstream auxiliaries are powered from the same shaft line. Rotational inertia is 0.00029 kg·m², so acceleration demands on the prime mover remain low. A mass of 4.8 kg supports easy handling during service, and FKM seals resist high temperature fluid and maintain leak tightness over long duty cycles.
