About the Saniflo FDA Series

Wilden is a global leader in sanitary, hygienic and biopharmaceutical applications. The Saniflo FDA series and Hygienic series meet the highest standards and requirements of these industries. The Saniflo Hygienic pump offers easy maintenance with CIP (clean in place) and COP (clean out of place).

The best performance With an eye for hygiene

This PS4-FDA Saniflo Hygienic is equipped with our latest new air slide system, the Pro-Flo SHIFT. The Pro-Flo SHIFT air slide features an air coil that limits the air supply to the pump each stroke ends. This eliminates overfilling of the air chambers and results in reduced energy consumption. With the Pro-Flo SHIFT air slide you can save up to 60% versus competitive air slide systems.
