The A4VG series axial piston pump is a high-performance hydraulic component widely used in various industrial applications. Here are the key details about this series:

1. Basic Features

• Type: Axial piston pump

• Series: A4VG

• Design: Swashplate design, which allows for variable displacement and flow control

2. Key Characteristics

• Variable Displacement: The flow rate of the pump can be adjusted by varying the angle of the swashplate. This feature enables the pump to match the flow requirements of the hydraulic system, optimizing efficiency and performance.

• Closed-Loop System: The A4VG series is commonly used in closed-loop hydraulic systems, which provide stable pressure and flow control, making them ideal for applications requiring precise control, such as construction machinery and industrial robots.

• High Pressure Capability: The pumps are capable of generating high pressures, typically up to 400 bar (40 MPa), making them suitable for demanding applications.

• Compact Design: The pumps are designed to be compact and lightweight, facilitating easy installation and integration into hydraulic systems.

3. Technical Specifications

• Displacement: Available in a range of displacements, typically from 28 cm³/rev to 250 cm³/rev, to suit different flow requirements.

• Maximum Pressure: 400 bar (40 MPa), with peak pressures up to 450 bar (45 MPa) in some models.

• Maximum Speed: Varies depending on the displacement, but typically ranges from 2,400 rpm to 4,250 rpm.

• Control Options: The pump can be equipped with various control options, including manual, hydraulic, and electronic controls, to suit different application requirements.

4. Applications

• Construction Machinery: Excavators, loaders, bulldozers, and other heavy equipment.

• Industrial Machinery: Hydraulic presses, injection molding machines, and other industrial applications requiring high-pressure hydraulic power.

• Mobile Equipment: Trucks, cranes, and other mobile machinery requiring precise hydraulic control.

5. Advantages

• High Efficiency: The variable displacement design enables the pump to operate at optimal efficiency across a wide range of flow rates.

• Stable Performance: The closed-loop system provides stable pressure and flow control, ensuring consistent performance.

• Durability: The pumps are built to withstand the rigors of demanding applications, offering long service life and reduced maintenance requirements.

• Flexibility: The range of displacements and control options allows for customization to suit specific application requirements.
