Product Overview
The Rexroth PGF1-21/3,2RA01VP1 (Material Number: R900932185) is a high-precision 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 chambers. This design delivers exceptionally smooth, low-pulsation flow with minimal noise emission. The PGF1 series is renowned for its compact construction, high volumetric efficiency, and ability to handle a wide range of hydraulic fluids, making it a reliable pressure source for machine tools, injection molding equipment, and general industrial power units.
