Product Description

HA4VSO Axial Piston Pump for Industrial Applications

Product Introduction

The HA4VSO axial piston pump is a high-performance variable displacement hydraulic pump designed for industrial applications such as steel metallurgy equipment and hydraulic power units. With a continuous operating pressure of 350 bar and maximum 400 bar, this pump provides reliable hydraulic power in heavy-duty industrial environments. Its robust modular design and precision engineering make it ideal for steel processing plants and energy-intensive machinery requiring consistent and powerful hydraulic performance.

Applications

  • Steel Metallurgy Equipment: Hydraulic presses, rolling mills, and forging machines.

  • Hydraulic Power Units (HPUs): Centralized hydraulic systems powering multiple machines.

  • Heavy Industrial Machinery: Applications requiring precise control and high-pressure operation.

Advantages

  • High Reliability: Engineered for continuous duty in industrial environments.

  • Pressure Compensation: Maintains constant system pressure up to 350 bar.

  • Energy Efficiency: Variable displacement matches flow to demand, reducing wasted power.

  • Low Noise Operation: Optimized port plate design reduces vibration and noise.

  • Modular Flexibility: Compatible with a wide range of industrial hydraulic systems.
