Kest Mixer Rapid Motion – RM

Finetuned to perfection.

Our RM 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.

Technical specifications

Perfect mixing result

After years of experience developing mixers this mixer will deliver a perfect mixing result over and over again.

ZERO particle shedding

The robust bearing combination of Zirconium and Sic and the fine-tuned geometry, ensures no particle generation.

Minimize downtime

The drive unit is equipped with our patented Kest-Lock connection that ensures quick disconnection from the tank plate during maintenance.

Vigorous mixing performance: meet the RM

The RM 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.

Vigorous mixing

The unique mixing head design with small wings allows to run the mixing head fast enough to create high-intensity mixing, it is a way of injecting more energy into the tank.
This is excellent when you like to incorporate powder that floats on top or easily creates lumps. It also works great for buffer tanks and upstream applications.

Robust bearing – ZERO particle shedding

The robust bearing combination of Zirconium and Sic and the fine-tuned geometry, ensures no particle shedding in your media. The higher bending strength of the zirconium 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.

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.

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.
