A10VD series axial piston variable displacement pumps—high-performance hydraulic solutions designed for demanding industrial and mobile applications. These pumps are engineered to deliver exceptional efficiency, reliability, and control in high-pressure systems.
The A10VD pump operates on the principle of an inclined disc axial piston mechanism, enabling stepless displacement adjustment by varying the swash plate angle. This allows precise control over flow and pressure, ensuring optimal performance under dynamic load conditions.
Key features of the A10VD series include:
Advanced Variable Control: Equipped with DR and FR control valves, the pump automatically adjusts the swash plate angle in response to system pressure and flow demands. At the set pressure (e.g., 14–22 bar), the DR valve activates to reduce displacement, maintaining constant pressure. The FR valve ensures stable differential pressure between port B and port X by compensating for flow variations.
High Efficiency & Low Noise: With volumetric efficiency exceeding 95%, the pump delivers outstanding energy savings while operating quietly. Its anti-cavitation design further enhances durability and performance in critical applications.
Constant Power Regulation: In high-pressure ranges (e.g., section BC), a dual-spring mechanism increases the slope of the pressure-flow curve, enabling constant power output. Integrated damping orifices prevent instability and ensure smooth regulation.
Modular & Flexible Design: The compact, modular structure supports through-shaft drive configurations, allowing easy integration into complex hydraulic systems. It is widely used in construction machinery, machine tools, and other heavy-duty equipment.
Available models include A10VD17, A10VD21, A10VD28, A10VD43, and A10VD71, offering a scalable solution tailored to various flow and pressure requirements.
