3" submersible pump for pressurization, gardening, irrigation and subsurface water removal tasks in residential building service. It can be installed in wells of at least 3" or in cisterns and tanks; Micra HS makes it possible to increase the pressure of the water trapped and to use it to water the garden or the vegetable garden. Micra HS is supplied with the Active Driver Plus variable frequency drive, which allows the pump motor speed to be adjusted according to requirements, thus allowing energy savings and increasing the maximum motor rotation speed (up to 130 Hz or 7600 rpm) to allow better performance compared to pumps of the same size. Pump and motor coupled by rigid joint. Non-return valve integrated in the cylinder head. Two-pole asynchronous submersible electric motor with stator immersed in thermosetting insulating resin, with high heat dissipation capacity and encapsulated in a hermetic stainless steel casing. The DConnect service makes remote control possible (with DConnect Box supplied separately).
