Upgrade Your NovAseptic Magnetic Mixer Bearings

Mix until the last drop

NovAseptic® magnetic mixers are frequently used in the biopharmaceutical industry, but their silicon carbide (SiC) bearings can be fragile and prone to particle shedding. KEST® NovAseptic® style Retrofit bearings made of zirconium dioxide (ZrO2) offer a durable, wear-resistant alternative. These bearings allow mixing at low liquid levels, reducing product loss and contamination risks, while improving efficiency and extending the life of your existing mixer. Enhance your mixing performance and ensure reliable, compliant production with this advanced bearing technology.

Key Advantages of the KEST® NovAseptic® style Retrofit bearings:

  • Mixing until the end
  • Long lifetime
  • No issues with particles in the process due to wear

Novaseptic standard

When selecting bearings for aseptic environments, NovAseptic® male bearings often encounter challenges such as wear, failure, and contamination risks. KEST® NovAseptic®-style retrofit bearings address these issues by delivering superior durability, minimal wear, and zero particle generation.

To substantiate this claim, KEST commissioned the RISE Research Institutes of Sweden to study particle generation during the mixing of water using KEST mixer bearings. The findings confirm the exceptional performance and reliability of KEST bearings in aseptic processes.

Novaseptic Bearings

Zirconium dioxide (ZrO2) is the ideal bearing material for pharmaceutical production due to its exceptional properties. Its hardness and wear resistance ensure long-lasting performance, even in high-shear mixing environments. ZrO2 is chemically inert, preventing contamination in sensitive processes, and resists corrosion from aggressive cleaning agents like CIP and SIP systems. Additionally, its smooth surface minimizes friction and particle generation, safeguarding product purity. These qualities make ZrO2 bearings a reliable choice for maintaining the stringent hygiene and safety standards required in the pharmaceutical industry.
