Description:

The Rexroth A11VLO is a variable‑displacement axial‑piston pump utilizing a swash‑plate design, engineered for open‑circuit hydrostatic drive systems. Its displacement is infinitely adjustable via swashplate angle, allowing flow output to match system demand — from zero up to maximum — which makes the A11VLO exceptionally versatile for mobile and industrial hydraulic applications. With optional charge‑pump support or self‑priming capability, plus through‑shaft drive for modular pump stacks, the A11VLO series delivers high power density, compact installation, and energy‑efficient performance under variable load conditions.

  • Infinitely variable flow & displacement — the swash‑plate design and adjustable swashplate angle, output flow can be precisely matched to load demands, improving system efficiency and reducing wasted energy.

  • High power density & compact footprint — delivers high flow and power output relative to size, making it suitable for mobile equipment and applications where installation space is limited.

  • Flexible control & application versatility — supports multiple control options (hydraulic, load‑sensing, electronic controls), optional charge‑pump or self‑priming operation, and through‑shaft modular drive configurations, enabling customization for diverse hydraulic systems.

  • High performance under variable loads — capable of delivering high pressure (nominal up to 350 bar, peak ~400 bar) and high torque, managing demanding hydraulic tasks efficiently.

  • Reliability and long service life — robust design, proven components and material quality make A11VLO suitable for heavy-duty industrial or mobile applications, even under fluctuating conditions.
