The P2GF2/013+GF1/2 2RE01+01E4 internal gear unit is part of the PGF Internal Gear Pumps series manufactured by Bosch Rexroth for hydraulic automation tasks demanding compact dual flow sources. Configured as a double pump, it supplies two separate circuits from a single drive while keeping noise and pulsation low. The front stage displaces 13.3 cm³ per revolution, so each rotation delivers that volume to the system. A right-hand, clockwise rotation matches common motor arrangements and simplifies shaft coupling. Continuous operation is allowed from 600 rpm up to 3600 rpm; within this band the pump can adapt to slow positioning movements or high-speed cycles. At 1450 rpm and 10 bar it provides a flow of 19.3 l/min, giving predictable output for standard industrial motors. The permissible working pressure reaches 210 bar, and short peaks may rise to 250 bar without damage. Suction conditions must stay between 0.6 bar absolute and 3 bar gauge when unloaded to prevent cavitation and seal stress.
The cylindrical keyed shaft end specified by ISO 3019-2 transmits torque to the front pump, and the drive can accept up to 140 Nm so the unit handles stiff starting loads. A low rotational inertia of 0.00014 kg·m² reduces acceleration demand on the prime mover, improving response in variable-speed drives. The front section weighs 4.6 kg, which eases manual installation in crowded manifolds. Both the front and secondary stages use ISO 228-1 BSPP ports, allowing standard tube fittings to be shared across the assembly and minimizing inventory. Maximum suction pressure capabilities outlined earlier remain valid for each stage because the connection standard preserves internal galleries. Together these characteristics support reliable supply to actuators in presses, machine tools, and mobile equipment where combined flows from a compact double pump increase circuit flexibility without enlarging the power unit.
