초록 ▼

A fluid pump assembly is used in combination with a container having a wall. The pump assembly comprises a first casing disposed outside the container in contact with the wall, a first magnetic assembly mounted to the first casing and operatively associated with a drive motor, a second casing disposed inside the container in contact with the wall, and a second magnetic assembly mounted to the second casing and operatively associated with an propeller. The first magnetic assembly includes a rotatable magnetic drive member drivingly coupled to the drive motor. The magnetic drive member is magnetically coupled to the magnetic driven member through the wall for imparting a rotary driving force of the drive motor to the propeller. Furthermore, the second casing is detachably connected to the second side of the wall of the container solely by magnetic attraction force between the first and second magnetic assemblies.

What is claimed is: 1. A fluid pump kit, comprising: a magnetic drive member coupled to a drive motor; a first casing supporting said magnetic drive member; a rotatable magnetic driven member coupled to a propeller; a second casing supporting said rotatable magnetic driven member; and a non-magnetic spacer separating said first and second magnetic assemblies; said drive motor and said propeller being magnetically coupled to each other by a magnetic attraction force between said magnetic drive member and said rotatable magnetic driven member through said spacer for drivingly coupling said drive motor to said propeller; said magnetic drive member being spaced from said spacer on one side thereof and said magnetic driven member being spaced from said spacer on an opposite side thereof; said second casing being detachably securable to said spacer solely by the magnetic attraction force between said magnetic drive member and said magnetic driven member sufficient to support said first and second casings in a particular position without the use of mechanical aids. 2. The fluid pump kit as defined in claim 1, wherein said magnetic drive member is axially aligned with said magnetic driven member. 3. The fluid pump kit as defined in claim 1, wherein said first casing houses said magnetic drive member therein and said second casing houses said magnetic driven member therein. 4. The fluid pump kit as defined in claim 1, wherein said drive motor is an electric motor. 5. The fluid pump kit of claim 1, wherein said magnetic drive and driven members are discs. 6. The fluid pump kit of claim 5, wherein each of said magnetic drive and driven members includes a plurality of magnetic poles. 7. The fluid pump kit of claim 6, wherein the magnetic poles are arrayed in a two-dimensional array. 8. A combination of a fluid pump assembly and a container having a wall, said pump assembly comprising: a first casing disposed exteriorly of said container on a first side of said wall; a magnetic drive member mounted to said first casing and spaced from said wall outside said container, said magnetic drive member coupled to a drive motor; a second casing disposed interiorly of said container on a second side of said wall; and a rotatable magnetic driven member mounted to said second casing and spaced from said wall inside said container, said rotatable magnetic driven member coupled to a propeller; said magnetic drive member being magnetically coupled to said magnetic driven member by a magnetic attraction force through said wall for imparting a rotary driving force of said drive motor to said propeller said second casing being detachably securable to said wall solely by the magnetic attraction force between said magnetic drive member and said magnetic driven member sufficient to support said first and second casings in a particular position without the use of mechanical aids. 9. The combination as defined in claim 8, further including a bracket member suspended from said container supporting said first casing only. 10. The combination as defined in claim 8, wherein said magnetic drive member is axially aligned with said magnetic driven member. 11. The combination defined in claim 8, wherein a shroud is mounted about said propeller. 12. The combination as defined in claim 11, wherein said shroud includes a plurality of slots formed in a sidewall thereof and a plurality of openings in an end thereof proximate said propeller. 13. The combination defined in claim 8, further comprising at least one first friction member attached to an inner face of said first casing facing said first side of said wall; said at least one first friction member is made of a material with a relatively high friction coefficient. 14. The combination defined in claim 13, wherein at least one first friction member is made of a resilient material. 15. The combination defined in claim 8, further comprising at least one second friction member attached to an inner face of said second casing facing said second side of said wall; said at least one second friction member is made of a material with a relatively high friction coefficient. 16. The combination defined in claim 15, wherein at least one second friction member is made of a resilient material. 17. The method of circulating fluid within a container, comprising the steps of: Providing a first casing having a rotatable magnetic drive member coupled to a source of rotary motion; Providing a second casing having a propeller coupled to a rotatable magnetic driven member; Providing a container having a fluid therein; Positioning the first casing on an exterior side of a wall of a container and positioning the second casing on an interior side of the wall of the container within the fluid in coaxial alignment with the first casing and allowing the casings to remain in alignment solely as a result of a magnetic attraction force between the rotatable magnetic members sufficient to support at least the second casing against gravity without the use of mechanical aids; Operating the source of rotary motion and thereby causing the first rotatable magnetic member to rotate for thereby causing cooperating rotation of the second rotatable magnetic member and of the propeller.
