Rexroth A10VSO Series Industrial Axial Piston Variable Pump

Product Overview: The Rexroth A10VSO series is a swashplate-designed axial piston variable pump specifically engineered for industrial Open Circuit hydraulic systems. As the globally recognized Series 31 benchmark, it is renowned for its ultra-stable pressure control and extended service life. By utilizing DR Pressure Control or DFR1 Load Sensing, this series modulates displacement in real-time to match system demand, significantly reducing power loss and making it the high-efficiency choice for industrial Hydraulic Power Units (HPU).

Key Technical Advantages:

• Precision Control Modulations (DR/DFR1):

  • Models A10VSO71DR and A10VSO18DR utilize Pressure Compensator control, de-stroking once the preset pressure is reached to maintain constant system pressure while saving energy.

  • Model A10VSO28DFR1 integrates Load Sensing (LS) to match flow exactly based on load pressure differentials, drastically suppressing system heat generation.

• Heavy-Duty Industrial Performance: Supports a rated operating pressure of 280 Bar (4000 PSI) with peak cycles up to 350 Bar (5100 PSI). Reinforced piston and slipper assemblies ensure peak volumetric efficiency under 24/7 operational conditions.

• Robust Thru-Drive Capability (VSC/VPA): Features superior thru-drive performance. Specifications like VSC12 or VPA42 allow for tandem mounting of a secondary pump, facilitating streamlined multi-circuit system integration.

• Low Noise & Extended Durability: Engineered with optimized dampening structures to reduce fluid pulsation and mechanical vibration, making it ideal for factory environments with strict noise regulations.
