Product Overview

The Rexroth A10VSO 18 DFR1/31R-PPA12N00 (Material Number: R910945178) 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 delivers infinitely variable displacement through precise control of the swashplate angle, enabling accurate flow and pressure regulation in response to system demand. The DFR1 control variant combines a pressure compensator with a load-sensing (flow) control, allowing the pump to match output to actuator requirements, minimizing energy loss and heat generation. With a nominal displacement of 18 cm³/rev and a size 31 frame, this pump is a direct-fit replacement for OEM installations and is widely deployed in open-circuit industrial machinery requiring reliable, efficient hydraulic power.
