The full-stroke design of these new diaphragms can increase the product displacement per stroke. This translates into greater flow rates and higher efficiencies than are found in pumps that operate with reduced-stroke PTFE diaphragms.The Full Stroke diaphragms use the same shaft and piston combinations as Wilden’s standard rubber and TPE (thermoplastic elastomer) diaphragms. They are retrofittable to existing pumps without the need for any extra components. Wilden's new Full Stroke PTFE Diaphragms are available on 1, 1.5, 2, and 3 in pumps.
