  • Patent number: 4890988
    Abstract: A canned motor pump wherein the can has two coaxial tubular walls defining an annular space for the flow of a heat exchange fluid which heats or cools the can. If the can has an end wall, the latter can be formed with an additional space which communicates with the annular space. The driven rotor within the can can be rotated by a stator which surrounds the can or by a hollow rotor which rotates the driven rotor by way of one or more magnets. The can can be heated by an electric heater.

  • Patent number: 4838763
    Abstract: A canned motor pump wherein the can has at least two coaxial tubular walls defining an annular space for the flow of a preferably gaseous fluid which is used to facilitate detection of leaks in the walls of the can. Each tubular wall can individually seal the driving unit from the driven unit of the pump motor. The leak detector can generate visible, audible and/or otherwise detectable signals, and such signals can also serve to stop the motor in the event of leakage.
