The PGH5-2X/125RE11VU2 pump belongs to the PGH High Pressure Gear Pumps series from Bosch Rexroth and supplies hydraulic automation systems with controlled oil flow for actuators and cylinders. Its displacement is 125.3 cm³ per revolution, determining the volume moved each time the drive shaft turns. When operated at 1450 rpm, the unit delivers 179.8 L/min, furnishing circuits that require a steady medium-to-high flow rate. A continuous pressure rating of 125 bar defines the maximum system pressure the pump can handle without reduced life. Clockwise rotation matches power units that use right-hand drives. The minimum operating speed of 400 rpm ensures sufficient internal lubrication and volumetric efficiency. The inlet side tolerates absolute pressures from 0.8 to 2 bar, a range that prevents cavitation while avoiding undue stress on the seals.
For short duty peaks, the pump accepts an intermittent pressure of 160 bar, allowing brief high-force movements in the hydraulic circuit. An SAE two-hole U2 mounting flange provides a standardized interface for engine or motor attachment. The 40 mm shaft diameter transmits torque while limiting torsional deflection under heavy load. A 1 1/4 inch SAE high-pressure outlet port offers compatible connection to downstream valves and manifolds. On the suction side, a 2 inch SAE port reduces inlet velocity and pressure drop. FKM sealing material resists mineral oil and elevated temperatures, extending service life during continuous operation. The pump weighs 45 kg, a consideration for lifting equipment and structural support during installation.
