The A4VTG/A4VG/A7VO/A8VO/A10VO/A11VLO/A20VG series hydraulic pumps serve as core power components for high-end hydraulic transmission scenarios. Based on a swashplate axial piston structure, they cover the application requirements of both closed and open circuits. With their high pressure, high stability and flexible adaptability, these pumps have become the preferred solution for construction machinery, energy equipment and other fields.
Hydraulic Pump Features
Integrated with multiple protection devices such as high-pressure relief valves, charge pumps and pressure cut-off valves, the pumps effectively prevent system overload. They support various control modes including hydraulic direct control, electric two-point control and proportional solenoid control, enabling remote operation and automatic adjustment.
4.Outstanding Durability
Adopting an optimized piston-cylinder block matching structure, the pumps reduce wear and pulsation. The built-in charge pump ensures stable oil supply, enabling long-term continuous operation under harsh working conditions with an extended service life.
The A4VG swashplate axial piston variable displacement pump is specially designed for closed-circuit hydrostatic transmission, serving as a reliable power core under high-pressure working conditions.
The A8VO hydraulic pump is a high-performance axial piston variable displacement pump adopting a bent-axis structure, equipped with two axial tapered piston rotating groups. It enables precise and efficient hydraulic control and can flexibly adjust the flow rate according to system requirements.The A7VO series hydraulic pump is a high-performance axial piston variable displacement pump independently developed . It is designed with a swashplate structure, which features a compact layout, high working efficiency and excellent pressure stability, making it a core power component widely used in various hydraulic systems.The A10VSO is a swashplate-type axial piston variable displacement pump for open circuits, whose drive shaft can withstand large axial and radial loads, achieving a good balance between durability and reliability.
