The Bosch Rexroth AA10VSO28DFR1/31R-PPA12N00 is a high-performance axial piston variable pump with a swashplate design, specifically engineered for open circuit hydraulic systems. It is widely used in demanding industrial and mobile applications due to its reliability, low operating noise, and long service life. The pump’s flow is directly proportional to the drive speed and displacement, which can be steplessly adjusted. This model features a DFR1 pressure and flow compensator, allowing for precise control and system efficiency. Its robust construction and high power-to-weight ratio make it a preferred choice for system integrators and machine builders.
