Product Overview
The Rexroth A10VSO 45 DFR1/31R-VPA12N00 (Material Number: R910967365) 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 45 cm³/rev and belongs to the A10VSO series size 45, part of Series 31. The DFR1 control variant combines a pressure compensator (DR) with a flow control (FR) function, enabling the pump to automatically adjust displacement in response to system pressure and flow demand. This results in precise load-matched output, reduced heat generation, and optimized energy efficiency. With a through-drive capability and ISO-compliant mounting flange, the A10VSO 45 is designed as a robust, long-life component suitable for continuous duty in open-circuit industrial hydraulics.

Engineering Features & Advantages
- Precision Swashplate Performance: The axial piston swashplate design delivers high volumetric efficiency and stable pressure output across the full displacement range, with fast response to changing load demands.
- DFR1 Pressure & Flow Control: Integrated pressure compensator and flow control allow the pump to maintain constant flow independent of load pressure, reducing throttling losses and system heat generation.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with heavy-duty bearings and hardened piston/cylinder interfaces for extended service life.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original OEM Rexroth A10VSO Series 31 standards, ensuring drop-in replacement 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 and flow control. It is also commonly deployed in construction and marine hydraulic systems where reliable variable displacement performance is essential.
