Product Overview

The Rexroth A10VSO 71DR / 31R-VPA42N00 (Material Number: R902482660) is a high-performance axial piston variable displacement pump engineered for open circuit industrial hydraulic systems. Featuring a swashplate design with a nominal displacement of 71 cm³/rev, this pump delivers exceptional pressure capability and precise flow control. The “DR” control variant denotes a pressure and flow controller (pressure compensator with remote control option), enabling the pump to automatically adjust displacement based on system pressure demand, thereby optimizing energy efficiency and reducing heat generation. As part of the renowned A10VSO series, this pump is a direct fit replacement for OEM installations and is widely trusted in demanding industrial applications requiring reliable, high-pressure hydraulic power.
