Bosch Rexroth PGH5-3X/080RE11VU2 internal gear pump

PGH5-3X/080RE11VU2, manufacturer material number R901147116, is a Bosch Rexroth PGH series 3X gap-compensated internal gear pump with fixed displacement. This clockwise execution has a keyed cylindrical shaft, through-drive and a two-hole ISO 3019-1 mounting flange.

The manufacturer’s RE10227 edition 2025-02 specifies geometric displacement 81.4 cm³/rev and a size-specific maximum operating pressure of 315 bar. Its 350 bar pressure-peak limit permits individual peaks no longer than 10 ms, with at most 300 hours of cumulative exposure. Suction and pressure connections are flange ports, not pipe threads.

Speed limits require 1 bar absolute suction pressure at permanent operating pressure or maximum drive power. Reference flow is measured at 1450 rpm and 10 bar with HLP46 at 50 °C and approximately 30 mm²/s. Pressure peaks are limited to 10 ms each and 300 hours in total. Actual drive sizing, hydraulic fluid, suction conditions and shaft loading must follow the selected original manufacturer pages. This single-pump rating does not establish a complete pump-combination rating.
