Diaphragm design

The FFKM diaphragm design improves the ability of a metering pump to resist absorption of media. The new diaphragm design, for fluid-handling applications, replaces the traditional polytetrafluoroethylene (PTFE) foil with a perfluoroelastomer (FFKM) layer that is bonded onto fluoroelastomer (FKM) pump diaphragms to improve stroke length, reliability, and durability in select applications.
