The PGH5-3X/080RE11VU2 pump is part of the PGH High Pressure Gear Pumps series produced by Bosch Rexroth. It supplies hydraulic oil to actuators where automated motion must be delivered at consistent pressures. The displacement volume is 81.4 cm³/rev, allowing a fixed flow rate proportional to shaft speed. A continuous outlet pressure rating of 315 bar enables the unit to drive cylinders and motors under steady load, while an intermittent limit of 350 bar tolerates short pressure spikes during rapid cycles. The shaft may turn at up to 3000 rpm to reach peak flow, yet the design remains stable down to 200 rpm for slow positioning tasks. Clockwise rotation is specified, ensuring correct housing orientation, and an SAE J744 152-2 (SAE D) mounting flange provides direct coupling to common industrial prime movers.
Operation in varied environments is supported by an ambient temperature range from –20 °C to +60 °C, so the pump can work in unheated yards or warm factory lines. Fluid temperature can vary between –10 °C and +80 °C, allowing use with typical mineral oils without exceeding seal or gear clearances. The hydraulic fluid must stay within a viscosity window of 10 mm²/s to 300 mm²/s; this range preserves volumetric efficiency and prevents cavitation across cold starts and full-load operation. An FKM seal set resists high temperature oil and common additives, reducing maintenance intervals. The assembly weighs 43.5 kg, which influences support structure sizing and handling during service.
