Product Overview
The Rexroth A10VSO28DFR1/31R-PPA12N00 (R902404112) 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 28 cm³/rev, this pump delivers precise pressure and flow control through its DFR1 control configuration, which combines pressure compensation (DR) with a flow/load-sensing function (FR). The through-drive capability allows multiple pumps to be combined in a single drive train, making it an ideal solution for demanding multi-actuator hydraulic circuits. Its robust construction and high power density ensure reliable operation in continuous industrial duty cycles.
