The unique design of the Wilden Saniflo™ Hygienic™ Series (HS) Pump incorporates a free-draining flow path that eliminates product-trap areas and enables clean-in-place (CIP) capability with lower risk of cross-contamination or compromised finished product. Additionally, the Saniflo HS pumps can be outfitted with Pure-Fuse Integral Piston Diaphragms (IPD), which use no adhesive in their construction. They feature a one-piece design that eliminates trap areas between the outer piston and the diaphragm. The design also puts an end to typical abrasion wear caused by the outer piston, resulting in longer service life. These features make Saniflo HS pumps the best choice for handling prepared food and sauces, beverages, poultry, dairy, cosmetic and pharmaceutical products.
