Canned motor pumps, especially those with internal circulation, are ideal for pumping fluids with high melting points. Because the pump and motor are combined into one unit with only one internal rotating part, the entire unit can be completely jacketed for either steam or electric tracing. This allows users to maintain a temperature above the melting point of the fluid, eliminating any â€œcold spotsâ€ where the liquid could solidify.
Common fluids with high melt points are Maleic and Phthalic Anhydride, resins and alkylated phenols. The use of a temperature probe is highly recommended to ensure the fluid is in a liquid state. Bearing wear detection or rotor position monitoring is also available.
