Product Overview
The Rexroth A10VSO18DFR1/31R-PKC62N00 (Material Number: R910946934) is a high-performance variable displacement axial piston pump engineered by Bosch Rexroth for open-circuit industrial hydraulic systems. Utilizing a proven swashplate design, this pump delivers precise, infinitely variable displacement control through a DFR1 pressure and flow (load-sensing) control configuration, allowing the pump to match system demand and significantly reduce energy consumption and heat generation. With a nominal displacement of 18 cm³/rev and a size 31 through-drive bearing configuration, the A10VSO18 is a compact, robust solution for demanding continuous-duty applications requiring high pressure capability and superior volumetric efficiency.
