Rexroth A11VO95 Series Pump | A11VO95LE2S, 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 crawler machinery, large-scale construction equipment, and heavy-duty industrial power units (HPUs). Its advanced control options, such as LE2S electronic 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-NPD12N00 feature reinforced rotating groups to maintain peak volumetric efficiency under continuous high-pressure loads.

• Advanced Electronic & Pressure Control (LE2S/DRS): Equipped with precision regulators. The LE2S specification (e.g., A11V095LE2S/10R-NSD12K01) provides electronic stroke control for seamless integration with electronic control units, while DRS features Load Sensing and pressure compensation for significant energy savings and reduced heat generation.

• Optimized Volumetric Efficiency: Utilizing reinforced slippers and an optimized valve plate design, the A11VO95 maintains peak mechanical efficiency even under high temperatures and low-viscosity media, ensuring stable torque output.

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