Product Overview
The Rexroth PGP2-22/011RE01VE4 (Material Number: R900932271) is a high-performance internal gear pump engineered by Bosch Rexroth for demanding industrial hydraulic systems. Utilizing the proven internal gear working principle, this fixed-displacement pump features a pinion shaft driving an internally toothed ring gear, with a crescent-shaped filler piece separating the suction and pressure zones. The PGP2 series is renowned for its exceptionally low noise emission, minimal pressure pulsation, and outstanding volumetric efficiency, making it an ideal choice for continuous-duty applications where smooth, reliable flow delivery is critical. With a nominal displacement of 22 cm³/rev and a clockwise rotation configuration, this pump delivers consistent hydraulic power for precision industrial machinery and mobile equipment alike.
