Rexroth A11VL0260 Series (Series 11) High-Displacement Variable Piston Pump

Product Overview: The Rexroth A11VL0260 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 A11VL0260 serves as the primary power source for large construction machinery 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 DR (Pressure Control) and DRS (Pressure Control with Load Sensing), 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:

  • DR Control (A11VL0260DR): Constant pressure regulation that automatically de-strokes the pump upon reaching the preset pressure, preventing system overload.

  • DRS Load Sensing Control (A11VL0260DRS): Dual pressure and flow modulation ensures the pump delivers only the exact power required by the load, drastically reducing energy waste.

• 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 (K02): The K02 code signifies through-drive capability, supporting tandem mounting of secondary pumps (piston or gear) to meet integrated power needs in multi-circuit systems.
