Product Overview
The Rexroth A10VO28 DR/31L-VSC12K01 (Material Number: R902450214) is a high-performance axial piston variable displacement pump engineered by Bosch Rexroth for demanding industrial and mobile hydraulic systems. Operating on the proven swashplate principle, this pump features a rotating group with precision-ground pistons and a tiltable swashplate that adjusts displacement based on system demand. The DR control variant incorporates a pressure-controlled (pressure compensator) regulator, which automatically modulates the swashplate angle to maintain a constant preset system pressure by adjusting flow output to match load requirements. With a nominal displacement of 28 cm³/rev and a size 31 frame designation, this pump delivers reliable, energy-efficient performance in open-circuit hydraulic systems, making it a direct-fit replacement for OEM installations requiring precise pressure and flow control.
