Rexroth A10VSO Series Industrial Axial Piston Variable Pump

Product Overview: The Rexroth A10VSO series is a premier axial piston variable pump engineered for Open Circuit industrial applications. As the cornerstone of the Series 31 family, it is renowned for its compact design, low-noise operation, and extended service life in machine tools, plastic machinery, and various Industrial Power Units (HPU). Ranging from the precise 28cc to the high-capacity 71cc (e.g., A10VSO71), this series utilizes advanced DR Pressure Control and DFLR Load Sensing to match flow and pressure demand perfectly, significantly optimizing energy efficiency.

Key Technical Advantages:

• Advanced Control Modulation (DR/DFLR):

  • The A10VSO28DR/31R features a DR pressure compensator, automatically reducing displacement once the preset pressure is reached to maintain constant system pressure.

  • The A10VSO45DFLR/31R integrates Load Sensing (DFL) and Pressure Compensation (R), sensing real-time actuator demand to minimize relief losses and system heat.

• Heavy-Duty Industrial Performance: Engineered for continuous high-pressure cycles. Supports a rated operating pressure of 280 Bar (4000 PSI) with peak cycles up to 350 Bar (5100 PSI). Reinforced bearings and valve plates ensure peak volumetric efficiency under grueling factory conditions.

• Superior Noise Reduction: Utilizing Rexroth’s patented dampening technology, the A10VSO suppresses fluid pulsation and mechanical vibration, making it ideal for quiet indoor industrial environments.

• Robust Thru-Drive Capability (K25): Suffixes like K25 indicate superior thru-drive functionality, allowing for tandem mounting of auxiliary pumps (gear or piston types) to streamline multi-circuit power distribution.
