Product Overview
The Rexroth A10VSO 140 DFR1/31R-VPB12N00 (Material Number: R902558641) 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 140 cm³/rev and belongs to the A10VSO series size 140, part of the 31 series production generation. The DFR1 control variant combines a pressure controller (DR) with a flow controller (FR), enabling the pump to automatically adjust displacement in response to system pressure and flow demand, thereby delivering energy-efficient operation with minimal heat generation. With a through-drive capability and ISO-compliant mounting flange, this pump is designed for open-circuit applications requiring high pressure, precise control, and long service life in continuous industrial duty.

Engineering Features & Advantages
- Precision Performance: The DFR1 control combines pressure and flow regulation in a single compact unit, automatically reducing displacement as system demand decreases — cutting energy consumption and minimizing oil heating in open-circuit systems.
- High-Pressure Capability: Axial piston swashplate design with hardened cylinder barrel and precision-ground pistons delivers reliable operation up to 280 bar continuous, suitable for high-load industrial cycles.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with robust bearings, low-noise operation, and long service intervals characteristic of the Rexroth A10VSO series.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original OEM standards, including mounting flange, shaft, and port configuration, ensuring drop-in replacement without system modification.
Typical Industrial Applications
This pump is widely deployed in plastic injection molding machines, metallurgical presses, CNC machine tools, and general industrial hydraulic power units requiring precise pressure and flow control. Its DFR1 control makes it particularly suited for systems with varying load demands, such as hydraulic presses, marine winches, and construction machinery where energy efficiency and stable operation are critical.
