-Diverse control methods: There are multiple control devices to choose from, such as pressure control, flow control, etc., which can meet the control needs of different hydraulic systems and achieve precise hydraulic adjustment.

-Widely used in various types of construction machinery, such as excavators, loaders, cranes, etc., to provide power support for the hydraulic drive system of these equipment, ensuring efficient operation and strong operational capabilities.

-In metallurgical equipment, hydraulic systems used to drive rolling mills, shearing machines, and other equipment can withstand harsh working conditions such as high temperatures and high loads.

-In the field of ships, hydraulic equipment such as servo systems and cargo cranes can be used for ships and have good resistance to corrosion in marine environments.

-In the machine tool industry, precise hydraulic power is provided for the hydraulic feed system, clamping system, etc. of the machine tool to ensure the machining accuracy and work efficiency of the machine tool.

The A7VO series pump can stably output high-pressure oil, ensuring the normal operation of the equipment.

-Efficient volumetric efficiency: Due to the circular parts of the plunger and plunger holes, highly precise fit can be achieved during the machining process, making this series of pumps have excellent volumetric efficiency. This means that within a unit of time, the pump can more effectively convert mechanical energy into hydraulic energy, reduce energy loss, and improve energy utilization efficiency.

-Good flow uniformity: The A7VO series pump has a uniform and stable flow output during operation. This is very important for equipment that requires precise control of movements, such as machine tools, where uniform flow can ensure stable tool feed rates during precision machining, thereby improving machining accuracy and surface quality.

-Oblique shaft structure: The axial conical plunger rotor group adopts an inclined shaft design, which makes the movement of the plunger smoother, reduces friction and wear, and improves the service life of the pump. At the same time, the inclined shaft structure can also withstand large radial loads to a certain extent, enhancing the reliability of the pump.

-Compact appearance: The overall design is compact, occupying small space, making it easy to install in various mechanical equipment, especially for limited space engineering machinery, ships and other equipment. The compact design of A7VO series pumps can better meet installation needs and will not occupy too much internal space of the equipment.

-Sturdy bearing system: With a sturdy and durable bearing system, it can withstand the axial and radial forces generated by the pump during operation, ensuring the stable operation of the pump rotor. The long-life bearing system reduces equipment maintenance costs and downtime, and improves equipment efficiency.

-Multiple control methods: There are multiple control devices to choose from, such as pressure control, flow control, constant power control, load sensitive control, etc. Users can choose appropriate control methods based on different work requirements and equipment characteristics to achieve precise adjustment and control of the hydraulic system, improving equipment performance and work efficiency.

-Continuously variable transmission: The flow rate is proportional to the transmission speed and displacement, and can achieve stepless changes within a certain range. This continuously variable speed feature enables the pump to flexibly adjust the output flow according to the actual needs of the equipment, meeting the operational requirements of the equipment under different working conditions.
