Product Overview

The Rexroth A10VSO 18 DFR1/31R-PPA12N00 (Material Number R910991846) is a high-performance axial piston variable displacement pump engineered by Bosch Rexroth for open-circuit industrial hydraulic systems. Featuring a swashplate design with a nominal displacement of 18 cm³/rev, this pump delivers precise, load-sensing flow control through its DFR1 control configuration, which combines pressure and flow (load-sensing) regulation with a pressure cut-off function. The A10VSO series is renowned for its high power density, fast response characteristics, and long service life, making it a benchmark component for demanding stationary and mobile hydraulic applications requiring accurate pressure and flow management.

Engineering Features & Advantages

Precision Swashplate Performance: The axial piston swashplate design with DFR1 control enables simultaneous pressure and flow regulation, delivering only the flow required by the load — significantly reducing energy consumption and heat generation in the system.
Load-Sensing Efficiency: Integrated load-sensing capability maintains a constant pressure differential across the control valve, ensuring precise actuator speed control independent of load variations.
Industrial Reliability: Built for continuous operation under severe industrial conditions with high-grade bearings and hardened piston/cylinder interfaces for extended service life.
Direct Fit Replacement: Exact dimensional and functional compatibility with original Rexroth OEM standards, ensuring drop-in replacement without system modification.

Typical Industrial Applications

This A10VSO 18 DFR1 pump is ideally suited for plastic injection molding machines, metallurgical presses, CNC machine tools, and general industrial hydraulic power units where precise pressure and flow control, energy efficiency, and quiet operation are critical. It is also widely deployed in construction and marine hydraulic systems requiring reliable variable displacement performance in open-circuit configurations.
