Description
1. Product Description
The Brueninghaus Hydromatik A10VSO71DFR1/31R-PPA12N00-SO405 is an axial piston variable displacement hydraulic pump from the A10VSO Series 31, associated with Bosch Rexroth hydraulic technology. Designed for open-circuit hydraulic systems, it supplies pressurized hydraulic fluid to industrial machinery, mobile equipment, and hydraulic power units.
The pump uses a swashplate design to adjust displacement and regulate hydraulic flow according to operating demand. Its DFR1 controller combines pressure and flow control functions, helping match pump output to system requirements. Typical applications include machine tools, presses, material-handling equipment, and industrial hydraulic power systems.
The nominal displacement is 71 cm³ per revolution. The A10VSO Series 31 family is rated for a nominal pressure of 280 bar and a maximum pressure of 350 bar, subject to the specific operating conditions and manufacturer’s limits. The complete ordering code, including the SO405 suffix, should be checked against the nameplate before replacement to ensure the controller, shaft, mounting flange, port configuration, rotation, and special-order specification match.
