MICRA HS 2/11 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 allows you to increase water pressure and use the water for watering your garden or vegetable patch. The Micra HS is supplied with the Active Driver Plus frequency converter, which adjusts the pump motor speed to suit requirements. This enables energy savings and increases the maximum motor speed (up to 130 Hz or 7600 rpm) for 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. The two-pole asynchronous submersible motor features a stator encapsulated in thermosetting insulating resin with high heat dissipation capacity and is enclosed in a hermetically sealed stainless steel housing. The DConnect service enables remote control (with the DConnect Box, available separately).
