The 76-mm (3”) Full-Stroke Integral Piston Diaphragm is ideal for use in Wilden’s Saniflo™ FDA pumps, as well as its Original™, Advanced™ and Advanced FIT air-operated double-diaphragm pumps. An integral piston is completely encapsulated within the TPE material, meaning there is no outer piston that can trap fluid and particles. A full-stroke design increases product displacement per stroke. Visit
