Powered by a stainless steel air distribution system, Wilden Saniflo sanitary FDA air-operated, double-diaphragm pumps feature 316 stainless steel wetted parts and tri-clamps for compatibility with sanitary piping systems. The air distribution system incorporates an air control spool that automatically restricts the amount of air going into the pump during the latter part of each stroke. The pumps are offered in 1 1/2-, 2- and 3-in. inlet/outlet sizes.
