The submersible motors canned type are motors with an airtight sealed and resin encapsulated stator.
This solution ensures an excellent heat exchange and an extremely high mechanical resistance in case of high pressure, something typical of really deep immersions.
The 4” water cooled submersible motors (4WM) keep some technical advantages of the oil filled submersible motor, such as:
the shaft’s projection until 3Hp power is made in AISI 304 stainless steel, while in motors bigger than 3Hp it is used a special type of stainless steel called DUPLEX. This one combines excellent resistance to corrosion and high mechanical resistance, a necessary features on engines with higher starting torques.
Besides above written features:
The above mentioned technical features, along with a meticulous manufacturing process and a double testing during assembly (Hydraulic and Electric) on 100 % of our production, guarantee a motor with higher technical performance and long term reliability.
