Teikoku USA Inc. offers a wide range of high temperature pumps for pumping liquids at high temperatures (usually above 400ºF). Most applications involve hot oil or hot water as the process fluid used as a heat transfer medium.
Depending on the pumping environment and plant requirements and capabilities, three designs are commonly offered for high-temperature applications:
A water-cooled canned motor pump designed for high-temperature applications isolates liquid in the motor section of the unit from the hot process fluid in the pump casing by a series of pressure ports located in the front bearing housing or pump casing adapter. This isolated liquid (usually the same fluid as the pumped fluid) is circulated through a liquid-cooled heat exchanger by an auxiliary impeller located on the rotor assembly. This design allows the motor and bearing environment to be at a much lower temperature than the process fluid, enabling the use of standard bearings and motor insulation significantly reducing both first and long term operating and maintenance costs.
