ABSTRACT:
A composite barrier can and method of making same for use with industrial magnetic drive pumps. The barrier can is used to prevent leakage between the inner magnet assembly attached to the pump and the outer magnet assembly attached to the pump drive or motor. The barrier can is a non-metallic, composite barrier can composed of fiber and resin and includes a pole piece. The nonmetallic material and high strength configuration of the composite barrier can permits pump operation at high speeds and pressures with negligible eddy current generation. Using the composite barrier can results in minimizing heat developed in the coupling area and minimizing horsepower required from the motor. A resistance temperature detector is operatively positioned on the exterior of or within the fiber layer of the can such that the sensing portion of the detector is located proximate the closed end of the can. A method of manufacturing the barrier can is also disclosed.
