Note: Always refer to the specific data sheet for the exact model (e.g., A4VSO 180 HD) for precise technical data.

3. Available Controls (Examples)

The pump's functionality is defined by its control. Common options include:

· HD Control: Pressure control. Adjusts displacement to maintain a preset system pressure (pressure compensation).
· EO Control: Electro-proportional displacement control. Flow is adjusted via an electrical input signal (e.g., 0-10V, 4-20mA), enabling easy integration with PLCs.
· LR Control: Power-limiting control. Limits the drive power consumption by reducing flow when a preset pressure is reached.
· EL Control: Electric control. Uses a solenoid valve to switch between two pressure settings.

4. Typical Applications

A4VSO pumps are versatile and are found in numerous industries:

· Metal Forming: Injection molding machines, stamping presses, extrusion presses.
· Machine Tools: CNC machining centers, grinding machines.
· Test & Simulation: Material testing rigs, fatigue testing systems.
· Mobile Machinery: Advanced and large-scale mobile equipment (certain models).
· General Industrial Machinery: Presses, rollers, winches, and any system requiring high-pressure, variable flow.

5. Why Choose the A4VSO Pump?
