Product Overview

The Rexroth A10VSO 10 DR / 52R-VPA14N00 (Material Number: R902453621) 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 pressure and flow control through a DR (pressure-controlled) regulator, automatically adjusting displacement to match system demand while maintaining a constant preset pressure. With a nominal displacement of 10 cm³/rev and a size 10 frame, this compact unit is ideally suited for applications requiring accurate pressure regulation, high volumetric efficiency, and long service life in continuous-duty operation. The A10VSO series is globally recognized for its robust construction, low noise emission, and superior performance in demanding industrial environments.
