Abstract
A canned motor pump is adapted for use at high temperatures and enables generated heat from the motor to be absorbed in a treating fluid or liquid upon circulation through the motor thereby conserving heat values in the treating fluid or liquid. The canned motor pump can circulate high temperature treating fluids, or liquids through the canned motor portion without damaging the coils of the motor because of a ceramic-like high temperature insulation used for the electrical field windings, which insulation is provided by mixing a silicone resin, synthetic fluoro-mica and a devitrified mica glass and impregnating the electrical winding coils with such material, whereafter the material is cured and then subjected to an elevated temperature above 300.degree. C. to form the ceramic-like insulation.
