Alfa Laval LeviMag® UltraPure Magnetic Mixer
The Alfa Laval LeviMag® UltraPure is a magnetic mixer with a levitating impeller designed to maximize product yield and mix product down to the last drop for the pharmaceutical and biotech industries. The four-wing impeller minimizes wear due to no direct contact between bearing surfaces. The LeviMag is available in five sizes featuring mixing speeds from 10 to 600 rpm. With the unique design of the magnetic coupling, the impeller is always levitating which allows for complete trainability and the free flow of CIP liquid around all parts of the mixer.
Alfa Laval is a leading global supplier of products and solutions within the key technology areas of heat transfer, separation, and fluid handling.
Application
Alfa Laval LeviMag UltraPure magnetic mixers offer effective mixing for multiple processes within pharmaceutical and biotech applications where high demands on hygienic and aseptic design are required.
Depending on duty and media properties the LeviMag can be configured to be used in tanks from 30 l. to 40,000 l.
Working Principle
A radial turbine installed inside the tank is rotated via the torque from a magnetic coupling. This creates mixing of the fluid inside the tank. The patented levitated design of the impeller makes the mixer fully drainable and able to run dry - hence it can mix to the last drop, securing maximum yield.
Unique Features
- Levitated Design: Makes the bearing fully drainable and minimize wear of the bearing.
- Replaceable Bearings: Both the female and the male bearing can be replaced by the end user on site.
- High Efficiency Impeller: The impeller unit is flow optimized, which creates the possibility of gentle product treatment.
- Mixing to the Last Drop: Dry running capability makes it possible to achieve maximum yield.
Available Versions
- Impeller with male/female bearing
- Impeller complete, with drive unit
Drive Unit Versions
- Painted (fan ventilated)
- Clean room finish, sealed surface conversion treatment (smooth, closed, no fan ventilated)
- Extended console for insulated tanks
