Mixing Made Simple

Polyvinylidene fluoride or PVDF has been used for more than 50 years in demanding chemical environments where corrosion resistance and absolute purity are required. PVDF is most commonly known by the tradename Kynar® and is manufactured by Arkema in Calvert City, KY. Our Purisan™ PVDF mixers are 100% Kynar® and build upon this solid legacy of dependable and consistent performance.  Our mixers, like all of the products at Nile Polymers, are 100% made in the USA.

Purisan™ impellers are injection molded from Kynar® PVDF which meets USP Class VI test requirements. These solid impellers eliminate the primary failure of powder-coated impellers: wear and abrasion on the leading edge of the blade. Continuous wear on the powder-coated surface exposes the underlying metal substrate resulting in corrosion and process contamination. Because Purisan™ impellers are solid Kynar® and 100% PVDF the risk of corrosion failure or metal contamination is minimal.

All Purisan™ PVDF impellers are mounted to a Kynar® powder coated 316 SST shaft using a threaded connection. The shaft is manufactured from pump shaft quality (PSQ) round stock. The impeller and shaft use a uniform thread size which allows rapid replacement without the cost and downtime of an entirely new fabrication. The threads on the shaft are uncoated and can be isolated from contamination by the use of a fluoropolymer gasket or o-ring.
