Product Description

Rexroth A11VO260 Series Ultra-Large Axial Piston Variable Pump

Product Overview: The Rexroth A11VO260 series is one of the most powerful specifications within the A11V family (displacement 260cc), engineered for massive Open Circuit high-pressure systems. Renowned for its unparalleled power density and stability under extreme loads, the A11VO260 is the premier choice for large-scale mining machinery, port equipment, and heavy industrial presses. Advanced LRDH2 and LRS control options provide precise hydraulic modulation, ensuring exceptional fuel economy even in peak pressure environments.

Key Technical Advantages:

  • Ultra-Large Displacement & High Pressure: Delivering 260cc per revolution, the A11VO260 supports a rated pressure of 350 Bar and peak cycles up to 400 Bar. Reinforced rotating groups and swashplate supports maintain peak volumetric efficiency under continuous heavy-duty load cycles.

  • Intelligent Power & Pressure Regulation (LRDH2/LRS):

    • LRDH2: Features constant power control, pressure cut-off, and hydraulic pilot regulation for dynamic matching with the engine’s power curve.

    • LRS: Provides Load Sensing (LS) and pressure compensation for on-demand oil delivery, significantly reducing system heat generation and energy waste.

  • Robust Thru-Drive Capability (K07/K86): Equipped with superior thru-drive functionality. The K07 and K86 suffixes indicate support for tandem mounting large secondary pumps, simplifying power layouts for massive multi-circuit hydraulic systems.

  • High-Reliability Design: Optimized for harsh mining environments, utilizing specially treated bearings and seals. The A11VO260 maintains an extended service life even in high-temperature or low-viscosity conditions, lowering total maintenance costs.

Detailed Models & Technical Parameters:

  • Core Models: A11VO260 (Series 11).

  • Detailed Config Codes: A11VO260LRDH2/11R-NPD12K07, A11VO260LRS/11R-NZD12K86.

  • Displacement: 260 cm³/rev (260cc).

  • Pressure Specifications: Rated at 350 Bar (35 MPa / 5100 PSI); Peak cycles up to 400 Bar (40 MPa).

  • Control Methods: LRDH2 (Power/Pressure/Hydraulic Adjust), LRS (Power Control / Load Sensing).
