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