Product Description

Rexroth A11VO Series High-Pressure Variable Axial Piston Pump

Product Overview: The Rexroth A11VO series is the ultimate heavy-duty drive solution for open-circuit hydraulic systems. Spanning displacements from 75cc to the massive 260cc, this series is engineered specifically for heavy-duty construction machinery and industrial equipment demanding extreme power density and long-term reliability. Featured models, such as the A11VO95DRS/10R-NPD12N00, integrate advanced pressure control (DR) and Load Sensing (S) capabilities. Operating at a continuous pressure of 350 Bar, the A11VO serves as the core power source for rotary drilling rigs, crane winches, and metal extrusion presses.

Key Technical Advantages:

  • Ultra-High Pressure Reliability: Rated for an operating pressure of 350 Bar (35 MPa) with peak cycles reaching 400 Bar. The reinforced rotating group is designed for an extended service life under the harshest operational conditions.

  • Sophisticated Control Modalities (DR/DRS/LR):

    • DRS Load Sensing: Accurately senses the actuator’s load demand, delivering only the required flow and pressure to minimize heat generation and energy waste.

    • LR Constant Power Control: Automatically modulates displacement to match the drive motor’s power curve, preventing overload while maximizing total power utilization.

  • Exceptional Suction & High-Speed Performance: Optimized inlet flow paths enhance self-priming characteristics and support higher rated speeds, reducing the reliance on charge pressure.

  • Robust Through-Drive Capability: Features powerful through-drive torque capacity, allowing for tandem mounting of secondary pumps (such as A10VO or gear pumps) for multi-circuit integration.

  • Compact Structural Design: Compared to pumps of similar displacement, the A11VO offers optimized dimensions, facilitating easier layout within cramped mobile machinery chassis.

Detailed Models & Parameters:

  • Core Series: Rexroth A11VO Series (Design 10/11).

  • Displacements: 75, 95, 130, 145, 190, 260 cm³/rev.

  • Representative Model: A11VO95DRS/10R-NPD12N00.

  • Rated Pressure: 350 Bar (5100 PSI).

  • Peak Pressure: 400 Bar (5800 PSI).

  • Rotation: R (Clockwise); L (Counter-clockwise).
