PGF1-2X/4 1RE01VU2

The PGF1-2X/4 1RE01VU2 pump is manufactured by Bosch Rexroth and belongs to the PGF Internal Gear Pumps series. It supplies hydraulic fluid in automation systems that rely on constant flow and low noise. A displacement of 4.1 cm³ per revolution sets the volumetric output for every shaft turn, enabling accurate dosing in small circuits. The shaft must rotate clockwise, so right-hand drive arrangements are mandatory. Mounting is completed with a 2-hole flange according to ISO 3019-1 size 82-2, which lets the pump bolt directly to standard motor adapters. The housing weighs 2.0 kg, keeping the combined motor-pump group easy to handle during maintenance. Minimum drive power at zero differential pressure is 0.75 kW, ensuring adequate torque for startup without unnecessary oversizing. A G 3/8 thread on the suction port matches common hose fittings used in compact reservoirs. The same G 3/8 thread on the pressure port simplifies spare-parts stocking because only one connector size is required.

A moment of inertia of 0.000021 kg·m² lowers acceleration demands on the prime mover during rapid indexing cycles. The pump can run continuously down to 600 rpm, which supports low-flow lubrication loops without bypass valves. Continuous duty at 210 bar allows the unit to serve medium-pressure clamping or feed circuits. It tolerates pressure peaks up to 250 bar, protecting the system from brief load spikes caused by directional changes. When driven at 1450 rpm the gear set supplies 6.0 L/min, satisfying the flow needs of actuators with modest speed requirements. Maximum transmissible drive torque is 30 Nm, so small electric motors can be coupled without overstressing the shaft. The shaft uses a DIN 6885 B4×4×14 key, providing positive engagement between pump and coupling hub.
