Wilden is proud to introduce its Full-Stroke Integral Piston Diaphragm (FSIPD). Constructed of Wil-Flex (Santoprene), they do not incorporate an outer metallic plate that requires the pump to be cleaned manually. Instead, the metallic plate is integrated into the material itself, resulting in a diaphragm design that uses the same shaft and inner piston as rubber and TPE diaphragms to maximize performance. FSIPDs are easy to install and do not require inverting of the diaphragm for installation. They do not use any adhesives that could get exposed to the pumping media. These piston diaphragms are FDA-compliant and feature flow, suction lift and efficiency comparable to rubber and TPE diaphragms with clean-in-place capabilities. They are available for use in 25 mm (1”), 38 mm (1-1/2”), 51 mm (2”) and 76 mm (3”) Hygienic Series pumps. These diaphragms can also be used in standard 25 mm (1”), 38 mm (1-1/2”) and 51 mm (2”) pumps, including the FDA-compliant Saniflo Series.
