Product Overview

The Rexroth A10VSO100 DR /31R-PPA12N00 (Material Number: R910912007) is a high-performance axial piston variable displacement pump engineered for open-circuit industrial hydraulic systems. Featuring a swashplate design, this pump delivers precise variable displacement control with a nominal size of 100 cm³/rev. The “DR” control variant denotes a pressure-controlled (pressure regulator) configuration, maintaining constant system pressure by automatically adjusting displacement based on load demand. Manufactured by Bosch Rexroth, a global leader in drive and control technology, this pump is designed for continuous duty in demanding industrial environments where high pressure, reliability, and energy efficiency are paramount. Its robust construction and advanced control capabilities make it a direct-fit replacement for OEM installations and a preferred choice for system integrators worldwide.
