S4 4" Tesla Motors

4” series high performance water filled submersible motors made of AISI 304 stainless steel (parts in contact with water). Encapsulated stator filled with inert gas avoiding the inflation of the inner casing and damages to rotor and shaft. This technology ensures that the motor can always be repaired. Lubrication of the motor and thrust bearing system is guaranteed by a water+glycol mixture; the motors are supported by Kingsbury type thrust bearing pads which ensure high axial thrust; all the motors are provided with a removable cable connector.
