Rexroth A10VO Series Axial Piston Variable Pump

Product Overview: The Rexroth A10VO series is one of the most versatile mid-to-high pressure axial piston variable pumps in the global hydraulic industry. As a cornerstone of the Series 31 family, it is renowned for its compact swashplate design, exceptional power-to-weight ratio, and rapid response times. Utilizing advanced DFR Load Sensing or DFLR Power Limiting controls, this series dynamically modulates output based on real-time system demands, drastically minimizing energy loss. From the precise 28cc to the high-output 74cc units, the A10VO ensures peak energy efficiency in any open-circuit system.

Key Technical Advantages:

• Intelligent Control Modulation (DFR/DFLR):

  • Models A10VO28DFR and A10VO71DFR feature integrated Load Sensing (LS), ensuring the pump delivers only the exact power required by actuators, reducing heat generation and extending seal life.

  • The A10VO74DFLR includes Power Limiting, preventing engine or motor stalls under heavy loads while optimizing overall power distribution.

• Heavy-Duty High-Pressure Performance: Engineered for Open Circuit systems with a rated operating pressure of 280 Bar (4000 PSI) and peak cycles up to 350 Bar (5100 PSI). Reinforced bearings and precision valve plates ensure extended service life under grueling conditions.

• Robust Thru-Drive Capability (K01/K02): Features superior thru-drive performance. Specifications like PSC62K02 or VSC42K01 allow for tandem mounting of a secondary pump, facilitating compact multi-circuit power distribution.

• Low Noise & Compact Envelope: The optimized housing structure not only dampens operational noise but also drastically reduces the installation footprint, making it ideal for injection molding machines, mini-excavators, and mobile machinery.
