Rexroth A10VO Series – Deconstructing the Core Subsystems

The reliability of the A10VO range—covering A10VO18, A10VO28, A10VO45, A10VO52, A10VO53, A10VO60, and A10VO63—comes from the tight interplay of several precision‑engineered components.

• Cylinder Block & Piston Assembly – Machined to extremely close tolerances, this rotating group cuts volumetric losses and internal bypass, sustaining high efficiency across the pump’s entire lifespan.

• Port Plate (Valve Plate) – This fixed interface governs the smooth changeover from low‑pressure intake to high‑pressure outlet, ensuring a steady flow with minimal ripple and sudden pressure surges.

• Control Piston (Servo Piston) – Functioning as the hydraulic actuator, this piston shifts the swashplate angle according to commands from the pump’s onboard control logic.

• Integrated Control Valves – Whether fitted with a pressure compensator (DR), a load‑sensing controller (LR), or an electro‑hydraulic proportional type, this valve block continuously adjusts displacement to match actual system needs, turning the pump into a self‑regulating power source.

Primary Applications – Powering Critical Machinery

Thanks to their blend of power, precision, and efficiency, these pumps are the preferred hydraulic drivers across diverse sectors.

Mobile Hydraulic Equipment

• In excavators and wheel loaders, they supply main power for boom, arm, and bucket movements. The load‑sensing feature gives fine, proportional control that operators appreciate, while cutting engine drag and fuel use during light‑load periods.

• For aerial work platforms and telehandlers, they ensure smooth lifting, extending, and positioning. Their dependable pressure‑limiting function acts as an essential safety guard against overloading in changing conditions.

Industrial Hydraulic Systems

• In plastic injection moulding machines, they provide the high peak flow needed for rapid clamp closing, then seamlessly switch to low‑flow, high‑pressure holding for exact cavity filling—directly improving part quality and cycle efficiency.

• On machine tools and automated lines, they drive clamps, rotary tables, and tool changers, where leak‑free and reliable operation is vital for maintaining accuracy and a clean workshop environment.

Strategic Advantages – Why Choose the A10VO Line

Investing in any model from A10VO18 to A10VO63 means better system performance and lower total cost over time.

• Superior Energy Economy – By supplying only the flow demanded, variable‑displacement technology slashes throttling losses and wasted power typical of fixed‑pump circuits, directly reducing fuel or electricity expenses.

• Responsive, Agile Control – Advanced control options such as LRDS (load‑sensing with remote pressure control) permit fuel‑optimised system designs that react instantly to operator commands, enhancing machine handling.

• Built for Long Service – With hardened internals, rugged journal bearings, and optimised internal lubrication, these pumps withstand severe duty cycles, delivering extended life and high mean time between failures (MTBF).

• Simplified, Reliable Systems – Integrated control functions often eliminate bulky external valve stacks, reducing piping, potential leak points, and overall system cost and complexity.
