A10VNO slant disc axial piston variable displacement pump and explore potential collaboration opportunities that can deliver mutual value in your hydraulic system applications.


The A10VNO pump stands out for its ability to enable stepless flow adjustment by varying the swashplate angle, combined with high-efficiency control mechanisms that significantly enhance energy utilization.  This makes it an ideal solution for demanding industrial and mobile hydraulic systems where precision, efficiency, and reliability are critical.


In construction machinery such as excavators and loaders, the pump’s load-sensing (LS) function dynamically matches flow demand through multi-way valves, reducing energy waste and improving operational efficiency.  For cranes and rollers, its constant pressure variable mode ensures stable system performance under fluctuating loads, enhancing both control and safety.


For industrial applications, the A10VNO offers robust performance under high-pressure conditions—rated at 280 bar, with peak pressure reaching 350 bar.  It is well-suited for heavy-duty equipment like forging presses and rolling mills.  With electric proportional control (EP model), it delivers a linear response between electrical signals and flow output, ensuring precise automation integration.  In injection molding machines, composite control options (DFR/DFLR) allow coordinated regulation of pressure, flow, and power, meeting complex process demands efficiently.


Additionally, the pump is engineered for specialized environments such as marine and high-temperature operations.  Equipped with heat-resistant fluororubber seals and a low-noise design, it performs reliably in deck machinery, anchor winches, and other shipboard systems, meeting stringent maritime operational requirements.


With a displacement range of 10–200 mL/r and rapid response characteristics, the A10VNO supports high-flow, high-pressure applications including gantry planers and large-scale hydraulic presses.  Its integrated FR valve (adjustable between 14–22 bar) enables a constant pressure differential across throttle valves, optimizing flow regulation and system stability.
