TW 4" Asynchronous two-poles submersible motor, made with a canned stator external shell made of AISI 304 stainless steel and coated cast iron top and bottom housings. Cooling and lubrication of the thrust bearing assembly and carbon bushes is provided by a mixture of water and glycol. Squirrel-cage rotor mounted on Kingsbury self-centering thrust bearing. Stator housed in an airtight resin filled stainless steel casing (canned-type) with both flanges and shell in AISI 304L stainless steel. Removable cable connector to allow fast and easy maintenance. The motor and cable are certified to CSA & UL electrical safety standards as well as NSF 61 & 372 drinking water standards.
On request is available the 4TWX version made entirely in stainless steel AISI 316.
