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.
