Product Overview
The Rexroth PGH4-30/040RE11VE4 (Material Number: R901016708) is a high-performance internal gear pump engineered by Bosch Rexroth for demanding industrial hydraulic systems. Operating on the proven internal gear 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. 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 a direct-fit replacement for the original Rexroth unit, ensuring seamless integration into existing hydraulic power units, lubrication circuits, and industrial machinery.
