Magnetic Mixers – KEST ProFlow
Aseptic magnetically coupled mixing technology for sterile and regulated production environments.
Why this solution?
Sterile mixing processes require maximum process safety, reproducible results and minimal maintenance – particularly in pharmaceutical and biotech production.
Conventional shaft-driven agitators may cause seal wear, leakage risks and increased maintenance intervals.
KEST ProFlow provides a hermetically sealed, magnetically coupled solution designed for critical hygienic applications.
Magnetically coupled – no rotating shaft seal
Energy efficiency above 95%
Cleanroom-optimized, fan-less drive unit
“Mixing to the last drop” – maximum product yield
Zero particle shedding bearing design (Zirconium + silicon carbide)
Real-time speed monitoring for process control
