Rexroth A11V0260 Series (Series 11) High-Displacement Variable Piston Pump

Product Overview: The Rexroth A11V0260 is a high-performance, swashplate-designed variable displacement pump engineered specifically for heavy-duty Open Circuit hydraulic systems within the advanced Series 11. Featuring a massive 260cm³/rev displacement and a rated operating pressure of 350 Bar, the A11V0260 serves as the primary power source for large construction machinery (such as 50-ton+ excavators) and heavy industrial equipment. It is renowned for its superior power density, high self-priming speeds, and exceptional service life. With sophisticated control options like LRS (Power Control with Pressure Compensation) and LRDH2 (Hydraulic Control with Power Modulation), it provides dynamic response to complex load demands, significantly boosting overall system efficiency.

Key Technical Advantages:

• Ultra-High Displacement & Power Density: The 260cc frame size delivers massive flow output while maintaining a compact footprint, meeting the high-speed requirements of heavy-duty actuators.

• Sophisticated Control Logic:

  • LRS Control (A11VO260LRS): Combines constant power regulation with pressure compensation, ensuring the pump operates on the optimal power curve to prevent engine/motor overload.

  • LRDH2 Control (A11VO260LRDH2): Integrates hydraulic pilot control with power modulation, supporting remote pressure cut-off and load-sensing logic for complex electro-hydraulic systems.

• Heavy-Duty High-Pressure Reliability: Rated for an operating pressure of 350 Bar (35 MPa) with peak cycles reaching 400 Bar. Reinforced rotating groups and low-friction bearings ensure structural stability under extreme continuous loads.

• Optimized Suction Performance: Specially designed inlet flow paths maintain excellent anti-cavitation characteristics even at high flow rates, extending total system longevity.

• Through-Drive Capability (K86/K07): Supports tandem mounting of secondary piston pumps or pilot gear pumps to meet integrated power needs in multi-circuit systems.
