Rexroth A10VO A10VSO Series Pump | A10VO28, A10VO100 | Tandem Piston Pump

Rexroth A10VO & A10VSO Series Axial Piston Variable Pump

Product Overview: The Rexroth A10VO (Mobile) and A10VSO (Industrial) series represent the most versatile mid-to-high pressure axial piston variable pumps in the global hydraulic industry. As a cornerstone of the Series 31 family, they are renowned for their compact swashplate design, exceptional power-to-weight ratio, and rapid response times. This series supports both single pump operation and Tandem Pump configurations (such as the A10VO100+A10VO100 combination). Utilizing advanced DR Pressure Control and DFR Load Sensing, these pumps deliver highly energy-efficient power for construction machinery, material handling, and industrial presses.

Key Technical Advantages:

• Intelligent Control Modulation (DR/DFR/DFR1):

  • The A10V028DR/31R features a pressure compensator, ensuring the pump de-strokes once the preset pressure is reached.

  • The A10VO100DFR integrates Load Sensing (LS) control, dynamically modulating flow based on actuator demand to maximize fuel and electricity savings.

• Robust Thru-Drive Capability (K07/Kxx): Features superior thru-drive performance. The PUC62K07 specification, for instance, allows for tandem mounting of a secondary piston pump, enabling combined flow and significantly boosting total system power output.

• 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.

• Low Noise & Compact Envelope: The optimized housing structure not only dampens operational noise but also drastically reduces the installation footprint, making it ideal for space-constrained modern machinery.
