Product Overview
The Rexroth A10VO45DFR1/31R-PSC12K01 (Material Number: R902511094) is a high-performance axial piston variable displacement pump engineered by Bosch Rexroth for open-circuit industrial and mobile hydraulic systems. Featuring a swashplate design, this pump delivers precise variable displacement control through a DFR1 pressure and flow (load-sensing) control module, allowing the pump to automatically adjust its output to match system demand. With a nominal displacement of 45 cm³/rev and a size 31 through-drive configuration, the A10VO45 is a proven workhorse in demanding applications requiring high pressure, excellent efficiency, and reliable continuous operation. The SAE mounting flange and splined shaft (PSC12K01 configuration) ensure direct drop-in compatibility with standard SAE installations.
