Kest Magnetic Mixer Rapid Motion


The Kest Mixer is a magnetic coupled mixer. With its aseptic design and excellent mixing performance it has become a popular choice for critical pharma and biotech applications. The Kest Mixer RM range is designed to incorporate more energy into the tank (eg. for dispersions) and covers mixing volumes up to 8 000 litres. The Kest Mixer is designed for CIP/SIP applications.

Easy operator handling of the drive unit is secured by our patented Kest-Lock Connection. With our revolution counter you will be able to have control over your process. The Kest Mixer RM range can be customized to perfectly fit your needs. We can manufacture the parts that have media contact in specific materials, please contact us.

Unique is the use of Zirconium dioxide (ZrO2) material for the bearings. Zirconium dioxide is chemically unreactive, therefor extremely suitable for applications in biotechnology and is delivered with a FDA and UPS Class VI certificate. It has great advantages over Siliciumcarbide. Zirconium dioxide is tougher and the possibility to accidental run dry. It also makes that de mixer can withstand the impact of bumps and shocks during the transport of the vessel. There are other improvements of the bearing, as shown on the page of the Kest-Mixer Standard male bearings. Also the mixerhead had some improvements to other mixers, for example the large radius of the edges of the female bearing, so there are no sharp edges which are weak spots for damage. The gap between the tank plate and mixerhead is wider, which makes the mixer less sensitive for solid addition. All these improvements gives the Kest-Mixer a higher durability and productivity.
