We mould diaphragm seals in many materials and constructions to suit the medium and the duty.
A diaphragm separates two media while transmitting pressure or motion. Because the diaphragm is the only moving part in contact with the fluid, material choice controls both chemical life and flex life — so we mould diaphragms in everything from NBR to FFKM, with or without fabric reinforcement.
