Product Overview

The Rexroth A10VSO140 DR /31R-VPB12N00 (Material Number: R902572347) is a heavy-duty axial piston variable displacement pump engineered for open-circuit industrial hydraulic systems. Featuring a swashplate design with a nominal displacement of 140 cm³/rev, this pump delivers high volumetric efficiency and reliable performance under continuous duty. The “DR” control variant denotes a pressure-controlled (pressure compensator) regulator, which automatically adjusts the swashplate angle to maintain a constant system pressure by matching pump output to downstream demand. Manufactured by Bosch Rexroth to stringent quality standards, this pump is a direct-fit replacement for OEM installations and is widely deployed in demanding stationary and mobile hydraulic applications.

Engineering Features & Advantages

Precision Swashplate Performance: The axial piston swashplate design delivers smooth, infinitely variable displacement with high volumetric and mechanical efficiency across the full pressure range.
Pressure Compensator Control (DR): Automatically modulates pump displacement to hold system pressure constant, eliminating excess heat generation and reducing energy consumption during holding or low-flow phases.
Industrial Reliability: Built for continuous operation under severe industrial conditions, with robust bearings and hardened piston/cylinder interfaces ensuring long service life.
Direct Fit Replacement: Exact dimensional and functional compatibility with original Rexroth OEM standards, ensuring drop-in installation without modification.

Typical Industrial Applications

This pump is ideally suited for plastic injection molding machines, metallurgical presses, CNC machine tools, and general industrial hydraulic power units requiring precise pressure control and high displacement capacity. It is also commonly found in construction and marine hydraulic systems where reliable variable-flow performance is critical.
