Cosmetics production has a lot in common with food: the product is usually a delicate emulsion, hygiene isn’t optional, and a harsh pump ruins texture that took real work to get right. Creams, lotions, gels and serums all want moving gently.
Wilden’s hygienic pumps do exactly that — a low-shear diaphragm stroke that carries emulsions and viscous creams without splitting or graining them, on cleanable, hygienic wetted parts that stand up to your CIP routine. The self-priming, run-dry-safe operation copes with the batch, stop-start rhythm of a cosmetics line too.
We supply these genuine and configured for your product and hygiene standard. Tell us what you’re making — its viscosity and how delicate — and we’ll recommend the right hygienic build.
