(1)Features
Magnetic couplings of the SMAK series are used to
transfer torque into mixers and agitators. Top drive, bottom
drive or lateral drive. Dangerous or precious media remain
isolated in the closed vessel.

(2)Advantages
• Magnetic coupling for mixers and agitators
• Hermetically sealed
• Sterile design
• Encapsulated magnets in the product space andElectro-polished surfaces when in contact with the product
• No contamination by buffer media
• No contact of torque transmitting elements
• No maintenance necessary
• Sliding bearing for bottom drives included
• Speed monitoring optional
• Weld-in or screw-in flanges available

(3)Functional description
The power transmission occurs contact-free through
magnets from the drive shaft to the product wetted output
shaft. Between the two rotating parts is the can wich is bolted to the container.
