Product Overview
The Rexroth A10VSO100 DR /31R-VPA12N00 (Material Number R910916809) is a heavy-duty axial piston variable displacement pump engineered for open-circuit industrial hydraulic systems. Featuring a swashplate design with a pressure-controlled DR (Pressure/Compensator) control, this pump automatically adjusts displacement to maintain a constant system pressure, delivering flow only as demanded by the circuit. With a nominal displacement of 100 cm³/rev, the A10VSO100 is a globally recognized workhorse for continuous-duty applications requiring high pressure, precise control, and long service life. As a direct OEM replacement, it ensures exact dimensional and functional compatibility with original Rexroth installations.

Engineering Features & Advantages
- Precision Swashplate Performance: The axial piston swashplate design delivers high volumetric efficiency and precise displacement control, ensuring stable flow and pressure across the full operating range.
- DR Pressure Compensator Control: Automatically reduces displacement to near-zero when system pressure reaches the set point, minimizing heat generation, energy consumption, and wear during holding phases.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with robust bearings and hardened piston/cylinder interfaces for extended service life.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original Rexroth A10VSO series pumps, 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. Its pressure-compensated control makes it particularly effective in systems requiring high holding pressure with minimal energy loss, such as clamping circuits, hydraulic presses, and automated production lines.
