Product Overview
The Rexroth PGF1-21/2.2RL01VM (Material Number: R900086166) is a precision-engineered internal gear pump from the Bosch Rexroth PGF series, designed for reliable hydraulic power generation in industrial and mobile applications. This fixed-displacement internal gear pump operates on the proven principle of an internally toothed ring gear meshing with an externally toothed pinion gear, separated by a crescent-shaped filler piece. The resulting design delivers exceptionally smooth, low-pulsation flow with minimal noise emission, making it ideal for applications where quiet operation and consistent volumetric performance are critical. With a nominal displacement of 2.2 cm³/rev and a clockwise rotation configuration, the PGF1-21/2.2RL01VM serves as a compact, energy-efficient solution for lubrication circuits, pilot pressure supply, and low-to-medium pressure hydraulic systems in demanding industrial environments.
