The A8VO pump is a high-performance solution designed for closed-loop hydraulic systems, widely applied across various heavy-duty equipment. Its core applications include rotary drilling rigs, where models such as A8VO107, A8VO120, and A8VO140 serve as critical power sources for main hoisting, power head rotation, and pressurization. The closed-loop system, enhanced by dual-pump merging technology, ensures rapid rotation response and reliable speed control under heavy loads, while integrated braking mechanisms prevent drill pipe slippage—critical for operational safety.
In excavators, the A8VO functions as either a main or auxiliary pump, delivering precise power regulation through variable displacement control. This significantly improves energy efficiency and responsiveness, making it ideal for frequent start-stop operations typical in excavation work.
For cranes and large crawler cranes ranging from 80T to 900T, the A8VO supports walking and slewing systems. Thanks to its pressure-balancing device, the closed circuit enables smooth braking and anti-reversal functionality, effectively reducing tipping risks during lifting operations.
Beyond these, the pump is also utilized in rollers, pavers, and concrete pumps, where electronic control within the closed system allows for accurate speed adjustment and robust overload protection.
Technically, the A8VO features an axial piston variable displacement design, adjusting output via the swashplate angle. Combined with full-power regulators and advanced flow control, it delivers superior dynamic response, energy savings, and overall system efficiency.
