REXROTH A10VSO 10 DR / 52R-PPA14N00 / R910990406

Product Overview

The Rexroth A10VSO 10 DR / 52R-PPA14N00 (Material Number: R910990406) is a high-performance axial piston variable displacement pump engineered by Bosch Rexroth for open-circuit industrial hydraulic systems. Utilizing a proven swashplate design, this pump delivers precise variable displacement control through its integrated DR pressure regulator, allowing it to maintain a constant preset system pressure by automatically adjusting displacement based on downstream demand. With a nominal displacement of 10 cm³/rev and a size 10 frame, this compact yet robust unit is ideally suited for applications requiring accurate pressure control, high volumetric efficiency, and long service life under continuous duty cycles.
