Product Overview
The Rexroth A10VSO140 DR /31R-PPB12N00 (Material Number: R910922983) is a heavy-duty axial piston variable displacement pump engineered for open-circuit industrial hydraulic systems. Featuring a swashplate design, this pump delivers high-pressure performance with a nominal displacement of 140 cm³/rev. The “DR” control variant denotes a pressure-controlled (pressure regulator) configuration, which automatically adjusts the pump’s displacement to maintain a constant system pressure, reducing energy consumption and heat generation during holding phases. Manufactured by Bosch Rexroth, a global leader in drive and control technology, this pump is a direct-fit replacement for OEM installations and is widely specified in demanding industrial machinery requiring precise pressure and flow control.
