Product Overview
The Rexroth A10VSO 28 DFR/31R-VPA12N00 (Material Number: R910910660) is a high-performance axial piston variable displacement pump engineered by Bosch Rexroth for demanding industrial hydraulic systems. Operating on the proven swashplate principle, this pump features a nominal displacement of 28 cm³/rev and is configured with the DFR control — a combined pressure and flow (load-sensing) controller that automatically adjusts pump displacement to match system demand. As part of the A10VSO series, it delivers exceptional volumetric efficiency, precise pressure regulation, and long service life in open-circuit applications. Its compact SAE mounting interface and through-drive capability make it an ideal primary or multi-pump configuration solution for mobile and industrial machinery requiring reliable, energy-efficient hydraulic power.
