Abstract
A magnetic coupling assembly includes a thermal isolation system that isolates the assembly from a heat source such as a pump coupled to a driven side of the assembly, thereby enabling the assembly to operate at a reduced temperature. The system may include a labyrinth seal that reduces convective heat transfer to the assembly. The seal may include a sealing gap defined between a rotating component and a stationary component. The gap is sized to limit gas conductance therethrough. The system may also include one or more spacers positioned to reduce or eliminate conductive heat transfer from one component to another. The assembly may be utilized in a pump for contactless coupling of a motor shaft to a pump shaft.
