Rubber diaphragm Code 54

PTFEEPDMelastomer

The GEMÜ code 54 diaphragm consists of a PTFE face and a peroxide-cured EPDM backing, which are securely connected to one another (fully laminated). An FKM backing is also available for highly permeating media (GEMÜ code 56). The PTFE used is a chemically modified second generation PTFE - called PTFE TFM ™. The diaphragm combines all the advantages of PTFE with the flexibility of an elastomer diaphragm in one product. In order to optimize the entire system, both the PTFE face and the diaphragm backing are compounded for GEMÜ and manufactured within the GEMÜ Group. Fabric reinforced EPDM backing (diaphragm size 25 to diaphragm size 100) Simple mounting thanks to the rubber pin that is vulcanized in place (diaphragm size 8) Simple and defined mounting thanks to the threaded pin that is vulcanized in place with integrated screw-in stop (diaphragm size 10 to diaphragm size 100) Sterilization temperature*: max. 150 °C Diaphragm materials: PTFE/EPDM * depending on version and/or operating parameters
