REXROTH A10VO 28 DR /31R-PSC62K01 -S0342 / R900442961

Product Overview

The Rexroth A10VO 28 DR /31R-PSC62K01 -S0342 (Material Number: R900442961) is a high-performance axial piston variable displacement pump engineered by Bosch Rexroth for open-circuit hydraulic systems. Utilizing a proven swashplate design, this pump delivers precise, infinitely variable displacement control by adjusting the swashplate angle, thereby modulating output flow to match system demand. The “DR” control designation indicates a pressure-controlled (pressure regulator) configuration, which automatically adjusts displacement to maintain a constant preset system pressure, significantly reducing energy consumption and heat generation compared to fixed-displacement alternatives. With a nominal displacement of 28 cm³/rev, this pump is ideally suited for demanding industrial applications requiring high pressure, superior volumetric efficiency, and reliable continuous duty operation.
