The Wilden chemical resistance guide is compiled from numerous reliable sources and cross-checked; however, it is only intended as an additional source of information. Diaphragm life not only depends on a diaphragm’s chemical compatibility with the process fluid but also on the process conditions. These conditions will vary depending on the abrasiveness of your process fluid, temperature, size of diaphragm, pumping media and lift conditions. Consult your authorized Wilden distributor regarding which diaphragm material will work best for your application requirements.
