Product Overview
The Rexroth PGH2-22/008RE07VU2 (material number R900951917) is a precision-engineered internal gear pump from the Bosch Rexroth PGH series, designed for reliable hydraulic power generation in industrial drive systems. Operating on the internal gear principle, this fixed-displacement pump features a pinion (outer gear) driving an internally toothed ring gear, with a crescent-shaped filler piece separating the suction and pressure chambers. This architecture delivers smooth, low-pulsation flow with excellent suction characteristics and low noise emission. The PGH2-22/008RE07VU2 is a direct-fit replacement component suitable for continuous duty in demanding hydraulic circuits, offering high volumetric efficiency and long service life with minimal maintenance.
