(1)Features
Magnetic couplings (MAK) are a hermetic sealing solution
for pumps and agitators. Dangerous or precious media
remain isolated in the closed system circuit.
(2)Advantages
• Magnetic coupling for standard applications
• Hermetically sealed
• No contact of torque transmitting elements
• No maintenance necessary
• Hastelloy® can for high performance
• High efficient can optional
• Product lubricated sliding bearing included
(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.
