What is a diaphragm seal?

The shaft seal is an elastomer diaphragm seal. This type of seal is a flexible membrane that seals and isolates an enclosure. It is very flexible which allows pressure effects to cross the barrier but not the material being contained. Common uses for diaphragm seals are to protect pressure sensors from the fluid whose pressure is being measured.
