Beschreibung
Zusammenfassung:	A magnetic coupling assembly (100) includes a first balancing magnet (128) positioned and surrounding drive magnets (120) and, across a gap (144), a second balancing magnet (132) positioned and surrounding driven magnets (124). The drive magnets (120), when rotated, drive the driven magnets (124) to rotate. The balancing magnets generate a repulsive force, which counterbalances an attractive force generated by the drive magnets and driven magnets. The assembly may be utilized in a pump for contactless coupling of a motor shaft to a pump shaft. The driven side of the assembly may be hermetically sealed, such as with a liquid crystal polymer boundary (552) interposed in the gap (144).
