Rexroth A10VO Series Axial Piston Variable Pump

Product Overview: The Rexroth A10VO series is the gold standard for mid-to-high pressure axial piston variable pumps in the global hydraulic industry. As the flagship of the Series 31 family, it is renowned for its compact swashplate design, exceptional power-to-weight ratio, and rapid dynamic response. This range features high-precision ED72 electro-proportional control models and energy-efficient DFR/DFR1 load-sensing units, providing precise pressure and flow management for any open-circuit system.

Key Technical Advantages:

• Sophisticated Intelligent Controls:

  • A10VO 28ED72: Equipped with electro-proportional pressure control for remote, stepless pressure adjustment via electronic signals, ideal for automated production.

  • A10VO71DFR & A10VO140DFR1: Features integrated load sensing (LS), ensuring the pump delivers only the exact power required by the system, drastically reducing heat generation.

• 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 ensure extended service life under grueling conditions.

• Superior Installation Flexibility: Includes thru-drive capability. Specifications like VSC92N00 or PQC62N00 allow for tandem mounting of a secondary pump, facilitating compact multi-circuit power distribution.

• Advanced Noise Reduction: Utilizing Rexroth’s patented dampening technology, the A10VO suppresses fluid pulsation and vibration even at high displacements like 140cc, making it ideal for indoor industrial environments.
