Wilden’s offering includes a number of material options that have been tested extensively over the years for use in AODD pump diaphragms. These materials can be grouped into three primary families: rubber, thermoplastic elastomer(TPE) and polytetrafluoroethylene (PTFE). These primary materials are available in a variety of designs – each offering unique benefits depending on the application and the characteristics of the product being pumped. Additionally, Wilden diaphragms are offered in a number of shapes, including traditional, contoured and convolute.
