How to Select Your Diaphragm
Determining the correct diaphragm requires carefully identifying and factoring all process and application parameters into the analysis. A number of factors must be taken into account when choosing the proper diaphragm suitable for a specific application.
Material compatibility with the fluid being pumped
Capability to remain flexible in low temperatures and not deteriorate in high temperatures
Ability to withstand wear and friction from contract with solids and particles in the fluid being pumped
Requirements that the diaphragm comply with hygienic or sanitary standards.
Expected longevity of the diaphragm before requiring replacement
Total cost of ownership determined by multiple factors such as initial price, rated flex life for the application and costs of downtime and diaphragm replacement labor
