Working principle: 

The magnetic agitating is an application of a magnetic coupling . 

Because the repulsion between the different poles of the magnetic material,we drive the magnetic agitator by

continuous changing the polarity of the  magnetic base. 

The shaft of motor and reducer connect with the inner  magneticring ,the agitation shaft connected with the

out  magneticring.  

The out  magnetic ring rotates with the inner magnetic ring ,and make the agitation shaft rotate according. 

The inner ring and outer ring are separated by the seal cover.  

So it is one of the most reliable No-leak design ,and a necessities for no leak reactors.
