Sterimixer consists of the following components:    
 

• Impeller
• Bearing
• Weld-plate
• Drive unit with magnet rotor
• Control box                                      

The impeller contains permanent magnets that create a magnetic coupling with the magnet rotor. The magnet rotor is coupled to a gear reducer and motor assembly. The bearing assembly provides a rotating surface to the impeller.

There is no physical connection between the drive unit outside the vessel, and the impeller inside. Therefore, there is no penetration to the vessel, which eliminates the need for any mechanical seal or other sealing devices.
