Product Overview
The Rexroth A10VSO 28 DFLR/31R-PPA12N00 (Material Number: R910946635) 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 rotating group of axial pistons that reciprocate within a cylinder barrel to generate flow, with displacement infinitely variable via swashplate angle adjustment. The A10VSO series is a globally recognized benchmark for medium-pressure open-circuit hydraulics, delivering exceptional volumetric efficiency, precise pressure and flow control, and long service life. The DFLR control configuration provides combined pressure and flow (load-sensing) regulation, making this pump ideally suited for systems requiring accurate actuator speed control independent of load variations.
