4" Submersible Motors

Features

Asynchronous motor with short-circuit rotor for single and three-phase current. Filled with non-polluting dielectric oil for proper lubrication and cooling. It rotates on properly sized ball bearings. Oil-bath winding (vegetable, dielectric, atoxic and non pollutant oil) ensuring the cooling and lubrication of all components. Rotor shaft on ball bearings of adequate size able to stand axial thrusts from 2000 to 6000 N, depending on the model. On motors with power over 2.2 kW; the thrust bearing is installed on the lower bracket. Hermetic sealing ensured by a mechanical seal provided with sand splash guard, oil volume increase offset by a membrane made of special rubber.
All components in contract with the water are corrosion resistant.
