The submersible motor series FMW4SS is water cooled with a resinate stator. It is built entirely in AISI 304 stainless steel. It is of the asynchronous type, 2 poles, with 24-slot stator and squirrel cage rotor. The special bearings reduce vibrations to a minimum, extending the life of the electric pump.
The resin insulation, with interchangeable cartridge, allows better cooling of the motor and in particular, better operation under inverter.

The power cable is equipped with a watertight plug, very useful in case of quick replacement on the installation site. The rotor shaft end is of stainless steel 304 up to 3hp, for bigger power DUPLEX. All motors are tested and tested at the end of the line.
