We are pleased to announce the release of our A4VG series hydraulic pumps, a swashplate axial piston pump with variable displacement, specially designed for hydrostatic drives in closed circuits. With a rated pressure of up to 400 bar and a peak pressure of up to 450 bar, the A4VG series provides precise, reliable hydraulic power for heavy-duty mobile machinery.

The A4VG series offers outstanding technical performance. Displacement is infinitely variable, with flow proportional to drive speed and displacement, and the flow direction reverses smoothly through the neutral position for bidirectional operation. An integrated charge pump ensures reliable boost and replenishing, while two pressure-relief valves protect the hydrostatic transmission under extreme conditions. A wide selection of control devices, including mechanical, hydraulic and electro-proportional controls, allows precise matching to each machine's requirements.

Thanks to their compact construction, high power density and versatile control options, A4VG series pumps are easy to integrate into closed circuit drive systems. They are widely used in excavators, wheel loaders, cranes, winches, concrete pump trucks and other mobile machinery. Various control, shaft, flange and port configurations are available, and OEM customization is supported.

With reliable quality, high efficiency and flexible customization, the A4VG series hydraulic pumps are ready to support your drive system needs. For specifications, customization or pricing, please contact our sales team.
