REXROTH A A10VSO 45 DFR1/31R-VPA12N00 / R910967365

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 and mobile hydraulic systems. Operating on the proven swashplate principle, this pump features a nominal displacement of 45 cm³/rev and is configured with the DFR1 control — a combined pressure and flow (load-sensing) control with a pressure cut-off function. The A10VSO series is renowned for its robust design, high power density, and excellent efficiency across a wide range of operating pressures. With a through-drive capability and ISO-compliant mounting flange, this pump serves as a central pressure source in open-circuit hydraulic systems, delivering precise, demand-matched flow to actuators while minimizing energy losses and heat generation.

Engineering Features & Advantages

Precision Swashplate Performance: The axial piston swashplate design delivers high volumetric and mechanical efficiency, ensuring precise displacement control and stable flow output across the full speed range.
DFR1 Load-Sensing Control: The integrated pressure and flow controller matches pump output to actual system demand, significantly reducing throttling losses, energy consumption, and thermal load in the hydraulic circuit.
Pressure Cut-Off Protection: The DFR1 control includes a pressure cut-off function that limits maximum system pressure, safeguarding downstream components and extending overall system service life.
Industrial Reliability: Built for continuous operation under severe industrial conditions, with heavy-duty bearings and a robust housing designed to withstand high pressure and demanding duty cycles.
Direct Fit Replacement: Exact dimensional and functional compatibility with original REXROTH standards, allowing straightforward retrofit into existing hydraulic systems without rework.

Typical Industrial Applications
