The A4VG series is a swashplate axial piston pump with variable displacement, specially designed for hydrostatic drives in closed circuits. With infinitely variable flow, bidirectional output and a rated pressure of up to 400 bar (peak 450 bar), it provides precise, reliable hydraulic power for heavy-duty mobile machinery.

Key features:

• Swashplate axial piston design for closed circuit hydrostatic transmissions.

• Infinitely variable displacement, with flow proportional to drive speed and displacement.

• Flow direction reverses smoothly through the neutral position for bidirectional operation.

• High pressure capability: rated up to 400 bar, peak up to 450 bar.

• Integrated charge pump for boost and replenishing.

• Two pressure-relief valves protect the hydrostatic transmission.

• Wide selection of control devices, including mechanical, hydraulic and electro-proportional.

• Compact construction with high power density.

Applications: hydrostatic drives for excavators, wheel loaders, cranes, winches, concrete pump trucks and other mobile machinery.

Customization: control, shaft, flange and port configurations can be tailored to your system; OEM supply is available.
