STEADYPRES 4.0 Electronic Variable Speed Pump Controller

STEADYPRES 4.0 Electronic Variable Speed Pump Controller

INSTALLATION & USE

STEADYPRES 4.0 is an inverter-based electronic control device compatible with both surface and submersible pumps, in single-phase or three-phase versions, up to 1.5 HP (1.1 kW). Installed on the pump delivery line, STEADYPRES regulates motor speed by modulating output voltage and frequency according to water demand, maintaining constant system pressure.

Designed for domestic water supply and irrigation applications, STEADYPRES integrates easily with any pressurization system, including existing installations. It improves user comfort, extends system service life, and delivers significant energy savings.

KEY FEATURES

Integrated pressure and flow sensors
Simple user interface with keypad and LED indicators for intuitive parameter monitoring
Quick and intuitive pressure adjustment via +/- buttons (1-9 bar)
Integrated, inspectable non-return valve
Rear threaded connection for installing a small expansion tank
Energy-saving with reduced pump absorption
Low noise operation
Minimal pressure drops
Extended pump lifespan

STEADYPRES can be paired with both single-phase and
three-phase pumps, featuring internal switches for configuration settings of the output frequency at 50 Hz or 60 Hz
the output supply voltage (single-phase or three-phase 230V )

STEADYPRES provides pump protection against:

Dry running
Overcurrent
Undervoltage
Overheating
Short circuit and current leakage
