A10VG series axial piston variable displacement pump—a high-performance solution engineered for demanding hydraulic applications in construction machinery, machine tools, and other industrial systems. With its advanced design and reliable operation, the A10VG pump offers an excellent opportunity for collaboration to meet growing market demands for efficiency and precision.
The A10VG operates on the principle of an inclined disc mechanism, enabling stepless displacement adjustment by varying the swash plate angle. Its core components include a plunger cylinder, swash plate, variable piston, and integrated control valve group. The stroke length of each plunger is directly influenced by the swash plate’s tilt, allowing precise control over fluid output.
In its initial state, spring force maintains the swash plate at maximum inclination, ensuring full displacement at startup. As system pressure approaches the preset threshold—typically between 14–22 bar via the DR pressure control valve—the control system activates, actuating the variable piston to reduce the swash plate angle and maintain stable pressure. This ensures energy-efficient operation under fluctuating loads.
For dynamic flow regulation, the FR valve continuously adjusts the swash plate angle in response to load variations, maintaining a consistent pressure differential between port B and port X. This responsive compensation enhances system stability and performance during real-time operations.
Notably, the pump features a constant power characteristic in high-pressure ranges. A dual-spring mechanism steepens the pressure-flow curve, optimizing power utilization while minimizing waste. Integrated damping orifices further enhance responsiveness and prevent instability or control oscillation during adjustments.
Designed with modularity in mind, the A10VG is easily adaptable to various system configurations. It delivers exceptional efficiency—exceeding 95%—along with low noise levels and strong resistance to cavitation, making it ideal for high-duty-cycle environments.
