Abstract
Layered barrier cans and methods of producing the same are disclosed herein. An example shroud disclosed herein includes an inner shell including a first non-metallic material, an outer shell including the first non-metallic material or a second non-metallic material, and a metal core shell positioned between the inner shell and the outer shell.
Claims20
A shroud for a pump comprising:
- an inner shell including a first non-metallic material, wherein the inner shell includes ridges extending away from a cavity defined by the shroud, wherein the ridges are spaced apart in a circumferential direction defined by the pump;
- an outer shell including the first non-metallic material or a second non-metallic material;
- and
- a metal core shell positioned between the inner shell and the outer shell, wherein the metal core shell spans an axial direction defined by the pump, wherein a span of the metal core shell in the axial direction extends from a first axial end to a second axial end, wherein the metal core shell is in contact with the outer shell at the first axial end and the second axial end.

A canned motor pump comprising:
- a first shaft including a first magnet;
- a second shaft at least partially positioned around the first shaft, the second shaft including a second magnet, the second magnet magnetically engaged with the first magnet;
- and
- a shroud positioned between the first shaft and the second shaft, the shroud including:
- a metallic core layer, wherein the metallic core layer is positioned between the first magnet and the second magnet in a radial direction defined by the canned motor pump, wherein a first portion of the metallic core layer includes a first outer diameter, wherein a second portion of the metallic core layer includes a second outer diameter different than the first outer diameter, and wherein the first portion and the second portion of the metallic core layer are defined at a same position along an axial direction defined by the canned motor pump;
- a first non-metallic layer positioned between the metallic core layer and the first shaft;
- and
- a second non-metallic layer positioned between the metallic core layer and the second shaft.

A magnetically driven pump comprising:
- means for housing a fluid;
- means for compressing the fluid;
- and
- means for sealing the means for housing, the means for sealing including:
- first means for insulating to define an inner surface of the means for sealing, wherein the first means for insulating includes means for stiffening;
- second means for insulating to define an outer surface of the means for sealing;
- and
- means for supporting the first means for insulating and the second means for insulating, the means for supporting to fill an area defined between the first means for insulating and the second means for insulating, wherein the means for supporting forms a portion of a means for coupling the means for sealing to the means for housing.
