Bracketless magnetic pump

A combination comprising:

• a container having a wall with opposite first and second sides, and
• a pump assembly comprising
• a first casing disposed exteriorly of the container on the first side of the wall;
• a magnetic driver mounted to the first casing and coupled to a drive motor;
• a second casing disposed interiorly of the container on the second side of the wall;
• and
• a magnetic driven member mounted to the second casing and coupled to a propeller;
• the magnetic driver being magnetically coupled to the magnetic driven member by a magnetic attractive force through the wall for imparting a rotary driving force of the drive motor to the propeller,
• the second casing and associated magnetic driven member being detachably securable to the wall solely by the magnetic attraction force between the magnetic driver and the magnetic driven member sufficient to support the second casing and magnetic driven member in a particular position without the use of mechanical aids.

A method of circulating fluid within a container, comprising the steps of:

• providing a first casing having a magnetic driver coupled to a source of rotary motion;
• providing a second casing having a propeller coupled to a magnetic driven member;
• providing a container having a fluid therein, the container having a wall with opposite exterior and interior sides;
• mounting the first casing with the magnetic driver on the exterior side of the wall of the container and positioning the second casing with the magnetic driven member on the interior side of the wall of the container in coaxial alignment with the first casing and allowing the casings to remain in alignment as a result of magnetic attraction between the magnetic driver and magnetic driven member, the magnetic attraction force being sufficient to support the second casing in a particular position against gravity without the use of mechanical aids;
• and
• operating the source of rotary motion and thereby causing the magnetic drive member and cooperating magnetic driven member to rotate the propeller.
