Wilden® Saniflo™ Hygienic™ Series Pumps for Hygienic and Sanitary Applications

Saniflo™ Hygienic™ Series (HS) Pumps are uniquely designed for high-cleanliness requirements and feature a free-draining flow path that enables clean-in-place (CIP) capability.

They are perfect for low-acid, pasteurized and protein-based products all the way up to biopharmaceutical sterile processes. HS pumps also meet the highest standards and requirements in the industry, including 3A, ATEX, EC 1935/2004 and FDA CFR 21.177.
