A10VO and A10VSO series of inclined disc axial piston variable displacement pumps—engineered to deliver superior performance, energy efficiency, and reliability across a wide range of demanding applications. With their ability to enable stepless flow regulation through precise control of the swashplate angle, these pumps have become a trusted choice in high-pressure hydraulic systems worldwide.
In construction machinery, the A10VO28DFR model is widely adopted in excavators and loaders, where its load-sensing (LS) function dynamically adjusts displacement in response to operational demand. This ensures optimal flow matching with multi-valve circuits, significantly improving energy efficiency. Similarly, in cranes and rollers, models like the A10VSO71DRG operate in constant pressure variable mode, maintaining stable system pressure while adapting seamlessly to fluctuating load conditions.
For industrial applications such as machine tools and metallurgical equipment—including forging presses and rolling mills—these pumps offer rated pressures up to 280 bar. Equipped with electric proportional control (EP), they provide a linear, responsive relationship between electrical signals and flow output, ensuring precision control. On injection molding machines, composite control variants (DFR/DFLR) effectively coordinate pressure, flow, and power to meet complex cycle requirements.
In marine and special-purpose equipment, such as deck machinery and anchor winches, the A10VSO100DR/31R-VPA12N00 features heat-resistant fluororubber seals and low-noise design, making it ideal for high-temperature environments and compliant with stringent onboard operational standards.
The forestry and agricultural sectors also benefit from our technology. The A10VO pump delivers robust power and flexibility for wood transport vehicles, ensuring reliable performance and stability even under extreme working conditions.
In architecture and infrastructure projects, compact yet powerful solutions such as the A24VG high-pressure pump and A10V series components enhance the sensitivity and controllability of bulldozers and excavator loaders, contributing to improved productivity and operator experience.
Technically, the series supports peak pressures up to 350 bar, with a displacement range of 10–200 mL/r, meeting the demands of heavy-duty equipment like hydraulic presses and gantry planers. The infinitely adjustable swashplate angle enables rapid response, and when integrated with an FR valve (set between 14–22 bar), it maintains a consistent pressure differential across throttle valves, enhancing system stability.
Thanks to modular design, anti-cavitation properties, and high-efficiency operation—reducing energy consumption by over 30%—these pumps represent a cost-effective, future-ready solution for modern hydraulic systems.
