HA4VSO Axial Piston Pump for Agricultural Machinery

Product Introduction

The HA4VSO axial piston variable displacement pump is a high-performance swash plate-type hydraulic pump engineered specifically for agricultural machinery applications. With a continuous operating pressure of up to 350 bar, it ensures stable and efficient hydraulic power for large tractors and combine harvesters. Its robust design and modular construction make it a reliable solution for demanding farming environments where durability and efficiency are critical.

Applications

• Large Tractors: Hydraulic power for steering, lifting, and transmission systems.

• Combine Harvesters: Efficient control of hydraulic functions such as header lifts, unloading augers, and threshing mechanisms.

• Agricultural Implements: Supporting hydraulically driven attachments requiring high pressure and precise control.

Advantages

• High Pressure Capacity: Continuous operation at 350 bar, maximum 400 bar.

• Energy Efficient: Variable displacement automatically adjusts flow to match system demand.

• Low Noise: Optimized fluid channels reduce operational noise, enhancing operator comfort.
