Magnetic Mixers
Magnetic mixers for plants in the pharmaceutical, biotechnological, cosmetic, food & beverage and chemical sectors, granting the maximum purity of the product inside the tank.
The AMT magnetic mixer is the ideal solution for mixing tanks in the pharmaceutical field. The transmission with magnetic torque avoids the occurrence of cross contamination between product and external environment, a typical problem of the use of devices with mechanical seals (shafts, seals and other equipment).
If the process requires the joining of several phases, it is possible to intervene by using the AMO magnetic homogenizer, which is completely interchangeable with the eventual AMT mixer present on the plant.
The geometry of the impeller allows an excellent axial pumping flow and very low shear rate for different applications:
- Mixing, dilution, maintaining in suspension.
- Speed range: 80 to 380 rpm using an inverter.
- Depending on the size of the vessel and impeller head, levels of agitation can range from vigorous to gentle. Small volumes can be effectively agitated.
- All product contact parts are made of AISI 316L stainless steel. The impeller head runs on a special grade bearing manufactured under controlled conditions to ensure correct size, grain structure, and hardness.
- The blade shape and profile are designed to optimize agitation levels and to direct a portion of the cleaning fluid through the head.

Principle of Operation
A machined pad is welded into the bottom of the vessel (usually offset with respect to the central axis). This design allows the drive unit to be dismounted, enabling sterilization of the tank in an autoclave. Meanwhile, the same drive unit can be installed and operated in another vessel.
The impeller head is driven by an externally mounted drive unit. Inside the impeller head, a ring of special magnets is encapsulated in a 316L stainless steel housing. The blades are welded to this housing, creating an integral impeller head.
