Magnetic agitators help to achieve high hygienic requirements
The BMR series of magnetic agitators have been designed to achieve the highest hygienic requirements needed when dealing with biotechnology, foodstuffs and pharmaceuticals industry environments.
They offer various benefits, such as absolute sealing, low maintenance requirements and more space on the tank cover for all types of connectors. The units of the BMR series from Zeta, a member of the Christ Water Technology Group, meet all requirements, which exist today for GMP-compliant production.
In particular, the open design of the magnetic impeller permits the important perfect cleaning in place (CIP). This has been proved in independent studies carried out by the Swiss University in Wädenswil in accordance with the three methods European Hygienic Engineering & Design Group (EHEDG), Total Organic Carbon (TOC) and Riboflavin. A further decisive property is the design of the ceramic sleeve bearing, whose generous dimensions and material combination (silicon carbide on zirconium oxide) offer the longest possible operating lifetime. Thanks to the hydrodynamic properties of the agitator blade and the patented "lift-off" lubrication channels, wear and the release of unwanted particles are almost negligible. If it should become necessary to replace the bearing sleeves, this can be done easily in situ.
These properties are also the reason for the increased use of the BMR magnetic agitators in the foodstuffs industry, since a reduced exposure to germs and bacteria can extend the shelf life of the product. The units are available with a transmittable torque of 0.3 Nm to 200 Nm for tanks with a maximum stirred volume of up to 45,000 litres. The Zeta product range also includes magnetic agitators for bioreactors, mixing units, conventionally sealed agitators and defoaming units.
