The KEST Retrofit bearing is an improved version of the NovAseptic bearing. Made of Zirconium dioxide ceramic, it can run dry without damaging. Making the mixing process far more efficient.

The bearings are 100% corresponding with the Silicon carbide NovAseptic bearings but have an extended lifespan because of the material. Zirconium dioxide is chemically unreactive, making it very suitable for applications in biotechnology. The biggest advantage over Siliciumcarbide (used by NovAseptic) is its toughness and robustness, making it able to run dry. The bearings are delivered with an FDA and USP Class VI certificate.
