Rexroth A11VO95 Series Pump | A11VO95LRDH1, A11VO95DRS | 350 Bar Variable Pump

Rexroth A11VO95 Series Heavy-Duty Axial Piston Variable Pump

Product Overview: The Rexroth A11VO95 series is a high-performance swashplate-type axial piston variable pump engineered for Open Circuit high-pressure hydraulic systems. As a core displacement model (95cc) within the A11V family, the A11VO95 is renowned for its exceptional power density and stable performance under extreme conditions. This series is widely utilized in heavy mobile machinery, large-scale construction equipment, and heavy-duty industrial power units (HPUs). Its advanced control options, such as LRDH1 power regulation and DRS load sensing, ensure a precise match between hydraulic output and load demand.

Key Technical Advantages:

• Superior High-Pressure Durability: Built for grueling environments, the A11VO95 supports a rated pressure of 350 Bar and peak cycles up to 400 Bar. Models like the A11VO95DRS/10R-NPD12K04 feature reinforced rotating groups to maintain peak volumetric efficiency under continuous high-pressure loads.

• Intelligent Control Strategies (LRDH1/DRS): * LRDH1: Features constant power control, pressure cut-off, and hydraulic pilot regulation, dynamically optimizing energy allocation based on system demand to drastically reduce fuel consumption.

  • DRS: Equipped with Load Sensing (LS) and pressure compensation for on-demand oil delivery, significantly reducing heat generation.

• Robust Thru-Drive Capability (K01/K04): Features powerful thru-drive functionality. The K01 and K04 suffixes indicate support for tandem mounting of secondary pumps (e.g., gear pumps), simplifying multi-circuit designs and saving valuable installation space.

• Superior Reliability Design: Utilizing specially treated swashplate bearings and low-friction materials, the A11VO95 maintains peak mechanical efficiency even in high-temperature or low-viscosity environments.
