Product Description
Rexroth A10VSO28DFR1/31R-VPA12N00 R910916805
The Rexroth A10VSO28DFR1/31R-VPA12N00 is a high-performance axial piston variable pump from the A10VSO series, specifically designed for open circuit hydrostatic drives. It employs a swashplate design, enabling variable displacement for precise control of hydraulic flow, which is proportional to the drive speed and the swashplate angle. This pump is renowned for its excellent suction characteristics, low operating noise levels, extended service life, and high power density. The integrated DFR1 control provides both pressure and flow compensation, enhancing overall system efficiency and responsiveness. It is a robust solution suitable for a wide array of demanding industrial and mobile hydraulic applications that require reliable and finely controllable hydraulic power.
