Rexroth A11VLO130LRDS/10R‑N12H45K – Compact Axial Piston Pump

Swashplate & Variable Displacement
Pistons in a rotating block slide against an angled swashplate. Steeper angle = longer stroke = more flow per rev. A hydraulic servo piston adjusts the angle on‑demand, so the pump delivers only what the system needs – no wasted flow, less heat, lower fuel use.

Key Specs

• 130 cc/rev nominal displacement

• 350 bar continuous / 400 bar peak

• LRDS control: load‑sensing (keeps 20 bar margin) + pressure cut‑off + torque limiter

• Robust cast housing, hardened internals, tapered bearings

Typical Applications
Excavators, cranes, wheel loaders – for smooth, proportional flow to multiple actuators. Also used in injection moulding presses and test rigs requiring fast, accurate pressure/flow response.

Maintenance Musts

• Fluid cleanliness: ISO 4406 18/16/13 or better; use β₁₀ ≥ 200 filters.

• Inlet pressure ≥0.8 bar absolute (flooded tank or charge pump).

• Case drain backpressure ≤0.5 bar – route direct to tank.

• Coupling misalignment ≤0.3 mm to protect bearings.

• Sample oil every 500 hours; watch case drain flow for wear signs.
