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
Maximize product yield and quickly realize return on investment due to the dry-running capability of the Alfa Laval LeviMag UltraPure magnetic mixer. Ensuring gentle product treatment is easy due to efficient mixing at very low speeds. The open design and low-speed rotation during cleaning contribute to no dead zones, effective residue removal and minimize contamination risks from wear particles.
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
The magnetic mixer transmits the required torque by means of magnetic coupling. The magnetic coupling consists of two sets of permanent magnets and a weld plate that separates the magnet sets. One set of magnets is mounted in the impeller (1) and the other set in the rotor (6). When the rotor revolves by means of the gear drive, the interaction between the two sets of magnets creates a magnetic coupling, which strenghting the rotation of the impeller. To avoid loss of magnetic coupling, it is necessary to gradually ramp up the rotation by means of a frequency inverter. The typical ramp up time is approximately 30 seconds. The frequency inverter is also used to adjust the speed.
Since the magnetic field couples across an air gap and through the weld plate(4), the tank is not compromised and therefore does not require a seal. This eliminates the risk of leakage and product contamination.
