Rexroth A11VO Series Pump | A11VO95LRDH1, A11VO130LR3S | 350 Bar Variable Pump

Rexroth A11VO Series Heavy-Duty Axial Piston Variable Pump

Product Overview: The Rexroth A11VO series is a premium swashplate-type axial piston variable pump engineered for Open Circuit high-pressure hydraulic systems. Covering displacements of 95cc and 130cc, the A11VO series is renowned for its exceptional power density and stability under extreme conditions. It is the primary power source for crawler machinery, large-scale construction equipment, and heavy-duty industrial presses globally. Its advanced LRDH1 and LR3S control options ensure a perfect match between hydraulic output and engine power.

Key Technical Advantages:

• Heavy-Duty High-Pressure Performance: Both A11VO95 and A11VO130 support a rated pressure of 350 Bar and peak cycles up to 400 Bar. Utilizing reinforced rotating groups, these pumps maintain peak volumetric efficiency under continuous heavy loads.

• Intelligent Power Regulation (LRDH1/LR3S):

  • The A11VO95LRDH1/10R-NZD12K82 model features constant power control, pressure cut-off, and hydraulic pilot regulation for dynamic energy optimization.

  • The A11VO130LR3S/10R-NZG12K01 model utilizes LR3S control for precise load sensing and power compensation, preventing system overload and significantly reducing energy waste.

• Robust Thru-Drive Capability (K82/K01): Equipped with powerful thru-drive functionality. The K82 and K01 suffixes indicate support for tandem mounting of secondary pumps, optimizing multi-circuit system design and saving valuable installation space.

• Superior Reliability Design: Utilizing specially treated swashplate bearings and low-friction materials, these pumps maintain peak mechanical efficiency even in high-temperature or low-viscosity environments, reducing overall maintenance costs.
