Product Description

Rexroth A11VLO145 Series Self-Priming Heavy-Duty Variable Pump

Product Overview: The Rexroth A11VLO145 series is a high-performance swashplate-type axial piston variable pump engineered for Open Circuit high-pressure hydraulic systems. As a specialized self-priming displacement model (145cc) within the A11V family, the A11VLO145 is optimized for the grueling environments of heavy mobile machinery. Thanks to its optimized suction port design (L specification), it maintains peak rotational speeds even at lower inlet pressures, effectively preventing cavitation. Core models like the A11VLO145LRDS are the primary choice for large excavators, rotary drilling rigs, and heavy-duty power units.

Key Technical Advantages:

  • Superior Self-Priming (L Spec): The enhanced flow path structure boosts suction capability, allowing the pump to operate stably at higher speeds without a charge pump, simplifying reservoir layouts and reducing the risk of cavitation.

  • Heavy-Duty High-Pressure Performance: Built for high-intensity load cycles, the A11VLO145 supports a rated pressure of 350 Bar and peak cycles up to 400 Bar, handling the shock loads of heavy lifting or excavation with ease.

  • Intelligent Control Precision (LRDS/LRS): * LRDS Models: Integrate constant power control, Load Sensing (LS), and pressure compensation to ensure maximum engine power utilization.

    • LRS Models: Provide power regulation and pressure compensation for on-demand oil delivery, significantly reducing heat generation and energy waste.

  • Robust Thru-Drive Capability (K01): Features powerful thru-drive functionality. The K01 suffix indicates support for tandem mounting of secondary pumps (e.g., gear pumps), optimizing the compactness of multi-circuit system designs.

Specific Models & Technical Parameters:

  • Core Models: A11VLO145 (Series 11).

  • Detailed Config Codes: A11VLO145LRS/11R-NZD12K01-S, A11VLO145LRDS/11R-NSD62N00.

  • Displacement: 145 cm³/rev (145cc).

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

  • Control Methods: LRDS (Power/Load Sensing/Pressure Control), LRS (Power/Pressure Control).
