Product Overview
The Rexroth A10VSO 28 DFR1/31R-VPA12N00 (Material Number: R910916805) is a high-performance axial piston variable displacement pump engineered by Bosch Rexroth for open-circuit industrial hydraulic systems. Featuring a swashplate design, this pump delivers precise variable displacement control through its DFR1 control configuration, which combines pressure and flow control with a pressure cut-off function. With a nominal displacement of 28 cm³/rev and a size 31 series designation, the A10VSO 28 is optimized for medium-pressure, high-efficiency applications where accurate flow regulation and energy savings are critical. The through-drive capability allows for tandem or multiple pump configurations, making it a versatile cornerstone component in demanding hydraulic power units.
