Rexroth A10VO A10VSO Series Pump | A10VSO45, A10VO71, A10VSO71 | 280 Bar Variable Pump

Rexroth A10VO & A10VSO Series Axial Piston Variable Pump

Product Overview: The Rexroth A10VO (Mobile) and A10VSO (Industrial) series are the most widely recognized mid-to-high pressure axial piston variable pumps in the global hydraulic industry. As the cornerstone of the Series 31 family, they are renowned for their compact swashplate design, exceptional power-to-weight ratio, and rapid dynamic response. By integrating advanced DFR Load Sensing or DFLR Power Limiting controls, these pumps achieve “flow-on-demand,” drastically reducing energy consumption and system heat generation.

Key Technical Advantages:

• Intelligent Control Modulation (DFR/DFLR):

  • Models A10VO71DFR1 and A10VSO45DFR feature integrated Load Sensing (LS), ensuring the pump delivers only the exact flow and pressure required by actuators for maximum energy efficiency.

  • The A10VSO71DFLR includes Power Limiting control, preventing motor or engine stalls under heavy loads and optimizing 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 (K02): Features superior thru-drive performance. Specifications like PSC62K02 allow for tandem mounting of a secondary pump, facilitating compact multi-circuit power distribution.

• Superior Noise Reduction: Utilizing Rexroth’s patented dampening technology, the A10VO/A10VSO suppresses fluid pulsation and mechanical vibration, making it ideal for noise-sensitive indoor industrial environments.
