What is a hygienic pump?

A hygienic pump is used in systems where cleanliness is vital to the product being pumped, such as food products, beverages, and pharmaceuticals. Hygienic pumps need to be able to be cleaned and sanitized on a regular basis and must be able to handle liquids gently. Indications that a pump is considered hygienic include certification of being an ATEX pump as well as other certifications.
