Kest Mixer – KM
Finetuned to perfection!
Our KM range of mixers is built on 30 years of mixing experience, packaged in a robust and user-friendly product. Everything from its mixing head design and the bearing materials is built for one thing: perfect flow. Every day.
Robust, reliable mixing performance: meet the KM
The KM Mixer is a bottom mounted magnetically coupled mixer with a user-friendly design and innovative engineering. Its unique design and many powerful features provide cost efficient, low maintenance processes with reliable mixing results.
Take advantage of full product recovery
The unique mixing head design and the position of the blades close to the bottom of the tank allows the mixer to run while the tank is being emptied. Mixing to the last drop with uncompromised cleanability.
Due to the low building height of the mixer head along with a lot of wing area close to the bottom the mixer is excellent in handling continues mixing of low levels as well.
Robust bearing – ZERO particle shedding
The robust bearing combination of Zirconium Oxide (ZrO2) and Silicon Carbide (SiC) and the fine-tuned geometry, ensures no particle shedding in your media. The higher bending strength of the Zirconium Oxide material enabled us to do the male bearing in one solid piece, this optimizes the aseptic design and increase the robustness and low wear property. The particle shedding test was done by the independent research institute RISE in Sweden according to USP<788> PARTICULATE MATTER IN INJECTIONS, no particles could be detected.
Total integrity of the tank
The Kest Mixer Tank plate is machined from a solid bar. The design is FEM analyzed to comply with PED and ASME pressure vessel code. The Tank Plate is welded into the tank and creates a solid barrier with no risk of allowing contamination of the media inside the tank.
Get full control of your mixing process
The KM can be equipped with an intelligent speed sensor system to control the actual movement of the mixing head in the tank based on the magnetic fields created.
The speed sensor system can detect that the mixing head is mounted in the tank, the rotation speed of the mixing head and the rotation direction – all of this is essential information to secure your validated mixing process.
Minimize downtime
The drive unit is equipped with our patented Kest-Lock connection that ensures quick disconnection from the tank plate during maintenance. When you put the drive unit back on the tank plate, the spring closed Kest-Lock helps the operator to hold the drive unit in place when tightening the screw to lock it in place.
On the larger mixer sizes we have a lowering device that will retract the outer magnet and release the mixing head for inspection with out removing the drive unit from the tank plate.
