The Alfa Laval LeviMag® UltraPure is an aseptic magnetic mixer that uses a patented levitating impeller and advanced design to mix down to the last drop and maximize product yield. Compact, energy-efficient and easy to maintain, it is perfect for biotech, pharmaceutical and demanding hygienic and sterile applications such as those involving serums, vaccines, plasma fractions, bacteria and cell cultures, and APIs.
Superior hygiene, optimized operation
- Optimized flow for higher efficiency and more gentle product treatment
- Mixing down to the last drop for maximum yield due to low agitation and dry-running capability
- Optimized Cleaning-in-Place thanks to full drainability
- Minimized downtime due to ease of maintenance
- Comprehensive documentation for full traceability of the entire supply chain
LeviMag® UltraPure Technology
The levitated design of the Alfa Laval LeviMag UltraPure prevents grinding between the axial parts of the bearings. This significantly minimizes the risk of damaging the media. This is important for pharmaceutical liquids that contain sensitive crystal carriers, for instance.
Get more uptime thanks to low-wear bearings that are easy to maintain and easy for operators to replace on site. No glue or shrink-fit is required. This minimizes downtime. Plus, there is no need for spare impellers. Tools for easy maintenance are also available.
The Alfa Laval LeviMag UltraPure magnetic mixer is available in five sizes from 100-300 mm. This provides greater process flexibility to handle a wide range of fluid types and mixing duties, such as high intensity mixing and gentle product mixing. For low viscous products and basic applications like keeping the product homogenous, the mixer can handle volumes up to 40 m3.
How it works
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 Alfa Laval LeviMag UltraPure impeller makes the mixer fully drainable and able to run dry; it can therefore mix to the last drop, securing maximum yield.
The unique design of the Alfa Laval magnetic coupling ensures the levitation of the impeller at all times. This enables the complete drainability of process fluids and the free flow of CIP liquid and steam around all parts of the mixer, thereby ensuring thorough cleaning. Impeller levitation also eliminates axial wear.
