Product Description

Rexroth A20VLO260 & A11VLO190 Series Heavy-Duty Variable Pumps

Product Overview: The Rexroth A20VLO and A11VLO series are premier axial piston variable pumps designed for massive Open Circuit high-pressure hydraulic systems. This range includes the 190cc single pump and the 260cc double pump, serving as the power core for large excavators, mining machinery, and industrial HPUs. Featuring the optimized L-specification (Self-Priming) design, these pumps offer superior suction performance without compromising rotational speeds, effectively mitigating cavitation risks and simplifying reservoir layouts.

Key Technical Advantages:

  • Efficient Power Matching (LG1S): Equipped with the LG1S constant power regulator, the pump dynamically modulates displacement based on load demand. This ensures the engine or motor operates at peak efficiency, preventing stalls and drastically improving fuel economy.

  • Heavy-Duty High-Pressure Performance: Both the A11VLO190 and A20VLO260 support a rated pressure of 350 Bar with peak cycles up to 400 Bar, handling extreme shock loads in heavy-duty excavation and lifting operations with ease.

  • Double Integration & Thru-Drive (K02): * The A20VLO260 integrates two units into a single housing with a shared suction port for unrivaled power density.

    • The K02 thru-drive capability allows for tandem mounting of secondary pumps (e.g., gear pumps), facilitating multi-circuit power distribution and optimizing system footprint.

  • Custom OEM Specifications (Y/S Suffix): Models such as A20VLO260LG1S/…-Y and A11VLO190LG1S/…-S represent specific pressure presets or specialized sealing, ensuring perfect compatibility in unique industrial environments.

Detailed Models & Technical Parameters:

  • Core Models: A20VLO260 (Series 10), A11VLO190 (Series 11).

  • Detailed Config Codes: A20VLO260LG1S/10L-NZD24K02-Y, A11VLO190LG1S/11R-NZD12K02-S.

  • Displacement: 190 cm³/rev (Single) / 260 cm³/rev (Double pump individual displacement).

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

  • Control Methods: LG1S (Constant Power Control / Pressure Compensation).
