Submersible motors of series FMO4 are asynchronous type, 2-pole with squirrel cage rotor, oil filled, rewindable.

They are very sturdy and oversized, to withstand heavy loads and last a long time even at great depths of immersion.

The power cables are equipped with connection plug to be sure that the internal cooling liquid, even if alimentary and non-toxic, FDA approved, can not climb by capillarity along the line.

A strong mechanical seal provides a long life to motor even in presence of sand.

The rotor shaft end is of stainless steel 304 up to 3hp, for bigger power DUPLEX. An oversized diaphragm of compensation allows the internal cooling liquid  to compensate differences of volume due to temperature variations.
