Product Overview
The Rexroth A4VSO 71 DR/10R-PPB13N00 (Material Number: R902423294) 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 71 cm³/rev and is configured with a DR pressure control (constant pressure) regulator, which automatically adjusts displacement to maintain a preset system pressure. The A4VSO series is renowned for its robust construction, high power density, and long service life, making it a benchmark component in heavy-duty open-circuit hydraulic drives. With its through-drive capability and ISO-compliant mounting flange, this model integrates seamlessly into multi-pump configurations and centralized hydraulic power units.
