Radially mounted magnetic coupling

摘要

An agitator tank with a magnetically coupled mixer. The mixer includes a drive magnet that is connected to a drive shaft. The drive magnet and drive shaft are both located within a drive housing that is fastened to the tank in a sealess fashion. The housing separates the drive magnet from a driven magnet that is attached to an impeller. The magnets are magnetically coupled so that rotation of the drive magnet induces a rotation of the driven magnet and impeller. The drive shaft is coupled to a motor which rotates the shaft and the drive magnet. The magnets are oriented so that the coupling surface of each magnet is essentially parallel with the longitudinal axis of the drive shaft, preferably in a circular pattern around the center of the shaft.
