PM 6” water cooled (6WM) submersible motors

Upper and lower bracket: Made in GS400 spheroidal cast iron with cataphoresis treatment, which gives great resistance to water impacts and corrosion. 6WM version fully made in 316 stainless steel available upon request.

Mechanical seal: Made in SIC-SIC, silicon-silicon carbide.

Stator: Specifically developed to achieve maximum electrical yield. Covered by an AISI 304 stainless steel sleeve. Windings are asynchronous-type and are made of cooper wire with  PE2+PA (6WM) insulation suggested for high temperatures and voltage surges. Both versions are suitable for use with inverter.

Filling liquid: Composed of a mixture of water and propylene glycol to ensure adequate lubrication of the thrust bearing system together with the ability to lower the freezing point when stored in very cold places.

Shaft: Completely made in AISI 431 stainless steel, without welding. It is ground along the entire axis thus giving the rotor such a concentricity to ensure perfect linearity. A shaft free from vibration is obtained thanks to balancing. Led by wear-resistant graphite bushing bearings. The 6WM version fully made in 316 stainless steel is equipped with shaft projection made in DUPLEX.
