Its Structure Is Composed Of Inner Magnetic Steel (With Stirring Paddle), Spacer Sleeve, Movable Bearing, Outer Magnetic Steel, Driving Device, Etc.

MagMix-A

The spacer can be removed from the tank. It is convenient for the maintenance inspection of the spacer sleeve. Avoid damage to the spacer sleeve resulting in the event that the tank needs to be cut.

MagMix-B

Can be disassembled as a whole from the tank. More convenient than MagMix-A type Maintenance, repair and installation are more
convenient. Suitable for small diameter tanks.

MagMix-C

The isolation sleeve is welded with the tank to reduce the maintenance and cleaning of the sealing ring.

Features:

Replacing The Mechanical Seal Of The Transmission Shaft With The Static Seal Of The Welded Isolation Sleeve Can Completely Solve The Leakage Problem That Cannot Be Solved By The Mechanical Seal. 2.Simple Structure, Low Maintenance Cost, Easy Disassembly, Easy Cleaning, No Dead Ends.
The Bottom Device Is Stirred, Which Can Be Stirred When The Material Is Small. The Unique Design Of The Stirring Blade Can Be Suitable For Stirring And Mixing Of Various Media. 
Can Be Idling For a Short Time.
