MICRA HS 2/5 3-inch submersible pump for boosting water pressure, garden irrigation, and drainage in residential buildings. It can be installed in wells with a diameter of 3 inches or more, or in cisterns and tanks. The Micra HS boosts the pressure of the pumped water, enabling it to be used for watering gardens or vegetable patches. The Micra HS is supplied with the Active Driver Plus frequency converter, which allows the pump motor speed to be adjusted to suit the specific requirements. This results in energy savings and increases the maximum motor speed (up to 130 Hz or 7600 rpm), ensuring better performance compared to pumps of the same size. The pump and motor are rigidly coupled. A non-return valve is integrated into the cylinder head. Two-pole asynchronous submersible motor with a stator encapsulated in thermosetting insulating resin, high heat dissipation capacity and a hermetically sealed stainless steel housing. The DConnect service enables remote control (with the DConnect Box, available separately).
