Product Overview
The Rexroth PGH4-30/020RE11VU2 is a high-performance internal gear pump engineered by Bosch Rexroth for demanding industrial hydraulic systems. Operating on the internal gear principle, this fixed-displacement pump features a pinion gear driving an internally toothed ring gear, with a crescent-shaped filler piece separating the suction and pressure chambers. This design delivers exceptionally smooth, low-pulsation flow with minimal noise emission, making it ideal for applications where quiet operation and precise volumetric consistency are critical. The PGH4 series is renowned for its robust construction, high volumetric efficiency, and long service life in continuous-duty industrial environments.
