The Micul Fermier MF-IR3040-G01 automatic pressure regulator is a modern water supply automation device designed to control the start and stop of water pumps based on pressure and flow in the system. This digital solution successfully replaces traditional systems (pressure switch + expansion tank + control valve), simplifying installation and improving equipment protection.

• Automatic pump control – starts and stops the pump as needed without manual intervention.
• Dry-run protection – protects the pump from costly damage.
• Easy installation and use – ideal for domestic water supply or irrigation systems.
• Replaces the classic control system (pressure switch, expansion tank, control valve), saving space and costs.

Key technical data

• Model: MF-IR3040-G01, Micul Fermier 1" automatic pressure regulator.
• Power supply: 230 V / 50 Hz.
• Maximum pump power: up to 1.5 kW.
• Starting/operating pressure: adjustable from 1–3 bar, maximum supported pressure 10 bar.
• Connector: 1" suitable for easy installation in the system.
• Maximum operating temperature: 60 °C.
• Water protection: IP65 for wet environments.

Operation

The pressure regulator monitors the pressure and water flow in the system as follows:

• When a tap opens or water consumption occurs, pressure falls below the set limit → the regulator automatically starts the pump.
• When pressure rises sufficiently or consumption decreases, the pump automatically stops.
• Dry-run protection stops the pump if there is no flow, preventing damage.

Main advantages

• Fully automated without traditional pressure switch and expansion tank.
• Protection against dry run and overload.
• Compatible with submersible and surface pumps up to 1.5 kW.
• Simple and safe installation, ideal for homes, gardens, and small farms.
