How the A8VO200 Works – Core Principle

A rotating cylinder block carries axial pistons whose shoes slide against a fixed‑angle swashplate. This tilt forces each piston to stroke in and out as the block turns: retraction draws oil in, extension pushes it out under pressure. The swashplate angle can be varied, giving infinite flow control.

Built for High Pressure, Compact Power

Rated for 350 bar continuous (higher peaks), the A8VO200 packs immense force into a small package – ideal for excavators and harvesters where space is tight. This power density often lets a single pump replace multiple units, simplifying system design.

Control Options – Tailored to the Task

Choose the regulator that fits your application:

• Pressure control (LR/HD) – automatically reduces displacement when system pressure hits a set point; used for standby pressure or overload prevention in presses.

• Load‑sensing (LV) – maintains a fixed pressure margin above load, adjusting flow to actual demand. Eliminates throttling losses, delivering major energy savings.

• Torque control (DA) – limits displacement to protect the engine from stalling, making best use of available horsepower in construction gear.

Durable Construction for Less Downtime

Rexroth’s precision manufacturing – hydrostatic balancing, optimized lubrication – minimises friction and wear. The pump withstands shock loads, continuous running, and dirty environments, extending service life and cutting total ownership cost.

Real‑World Examples

• Injection moulding – delivers high flow for fast clamp close, then shifts to high‑pressure low‑flow for holding. This ensures part consistency, shorter cycles, and lower energy use.

• Forestry cranes – with LV control, provides smooth, proportional handling of heavy logs on uneven ground.

• Marine winches – resists corrosion; variable displacement lets auxiliary engines run at fuel‑saving speeds, adapting output to the load rather than running flat out.
