Double-diaphragm pumps

Full-stroke PTFE (Teflon) diaphragms are now available for Wilden's Advanced Series air-operated double-diaphragm pumps. By allowing increased product displacement per stroke, the full-stroke diaphragms produce greater flow rates and higher efficiency than reduced stroke diaphragms. Because they use the same shaft and piston combinations as the company's standard rubber and TPE diaphragms, they can be easily retrofitted to existing pumps with no extra components. The full-stroke PTFE diaphragms are available for Wilden 1, 1.5, 2 and 3 inch pumps.
