Bracketless magnetic pump

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.

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.
