The PGH4-2X/080RE07VU2 unit is manufactured by Bosch Rexroth and belongs to the PGH High Pressure Gear Pumps series, where it supplies hydraulic power for automated machinery. A displacement of 81.40 cm³ per revolution defines the volume moved each shaft turn, and a flow rate of 116.9 l/min at 1450 rpm and 10 bar shows the output achievable in standard test conditions. The pump holds a continuous pressure rating of 315 bar, while a maximum operating pressure of 350 bar allows short-term peak loading without damage. Clockwise rotation is specified to align with drive trains that use right-hand shafts, preventing reverse flow or mechanical mismatch. These characteristics combine to deliver consistent high-pressure supply for servo valves, cylinders, and other hydraulic automation elements.
The pump can run up to 3000 rpm and down to 200 rpm, giving designers a wide speed window for variable-displacement drives. A moment of inertia of 0.00289 kg·m² keeps acceleration demands modest so electric motors or diesel engines see reduced starting torque. The minimum absolute inlet pressure is 0.8 bar, which protects against cavitation when reservoirs sit below the pump. Fluid temperatures between −10 °C and +80 °C are permitted, supporting both cold-start and warm-running conditions. Mounting is through an ISO 3019-1 152-2 (SAE D) flange for direct fit on common motor bell housings, and the line connection uses a standard-series SAE flange that simplifies hose routing. An FKM seal resists hot oil and additives, extending service intervals. The assembled weight of 43.5 kg must be considered when selecting support brackets or lifting methods.
