Technical Specifications 

• Product Series: Rexroth A11VO Series Axial Piston Variable Pump

• Representative Model: A11VO260LRS/11R-NZD12N00

• Displacement Range: 60 cc/rev to 260 cc/rev

• Rated Operating Pressure: 350 bar (5075 psi)

• Max Peak Pressure: 400 bar (5800 psi)

• Max Speed: 1500 – 2500 rpm (Model-dependent)

• Control Mode: LRS (Load Sensing / Pressure Compensation), compatible with DR/DRS/LR

• Structural Configuration: Axial piston variable displacement, swashplate design

Key Technical Advantages:

• High-Dynamic Variable Mechanism: Utilizing advanced servo-control valves, the swashplate angle shifts rapidly, achieving millisecond-level pressure or flow response. This significantly enhances the operational smoothness and agility of heavy-duty machinery.

• High-Strength Cylinder & Piston Pair: Cylinder bore and valve plate surfaces undergo specialized anti-wear coating, providing ultra-low friction characteristics under high-pressure oil film conditions. This minimizes internal leakage and ensures sustained volumetric efficiency over long-term operation.

• Load-Adaptive Control System: The LRS load-sensing system dynamically adjusts pressure and flow according to load requirements. This minimizes energy loss from overflow, achieving the perfect balance of efficiency and power for heavy-duty drive circuits.

• Long-Life Heavy-Duty Bearing System: The internal drive shaft is supported by large-scale heavy-duty rolling bearings, providing exceptional radial load-bearing capacity. This ensures long-term structural stability under continuous high-pressure and high-speed operational cycles.

Application Areas:

• Construction Machinery: Main hydraulic power systems for excavators, bulldozers, and cranes.

• Mining Equipment: Hydraulic power units for large-scale surface drills and crushing equipment.

• Metallurgical Systems: Continuous casting units, conveyor systems, and auxiliary production circuits.

• Industrial Power Stations: High-precision hydraulic power units for large presses and injection molding machines.

Expert Maintenance Tips:

• Case Filling & Pressure Monitoring: Always fill the pump housing with clean hydraulic fluid through the case drain port before startup. Never start the pump with an empty casing, as it will cause instantaneous scoring of the slipper and valve plate.

• Suction Vacuum Check: The A11VO series is sensitive to suction resistance. Ensure suction lines are unobstructed, of sufficient diameter, and free of excessive bends. Keep absolute vacuum below 0.8 bar to prevent cavitation.

• Fluid Cleanliness Standards: The servo spool within the pump is extremely sensitive to contamination. Maintain system fluid cleanliness at ISO 4406 18/16/13 or better, and we strongly recommend the installation of a 10μm pressure-line filter for optimal protection.
