Two new diaphragms for demanding chemical applications
GEMÜ Code 71 three-layer PTFE/PVDF/EPDM diaphragm
The GEMÜ Code 71 three-layer diaphragm has been specially developed for use with corrosive and volatile media. It comprises a PTFE face, an intermediate layer made of PVDF and an EPDM backing. With regard to the PTFE face, the diaphragm is based on the tried-and-tested design and dimensions of the well-known Code 5M diaphragm. For applications with industrial gases, the additional PVDF intermediate layer offers excellent permeation properties. Thanks to the high-quality material selection, the diaphragm is resistant to corrosive chemicals such as volatile acids, oxidizing agents and salts, as well as humid chlorine, bromine and their derivatives.
The GEMÜ Code 71 diaphragm is available in diaphragm sizes 10 to 100 and is used in PFA-lined valve bodies from GEMÜ’s product range.
GEMÜ Code 5T two-layer PTFE/FKM diaphragm
The GEMÜ Code 5T diaphragm is a two-layer diaphragm, comprising a PTFE face and an FKM backing. The PTFE that is used is a chemically modified second-generation PTFE, which is known as TFM™. The diaphragm has been developed for use in industrial applications, for example in the chemical industry, environmental engineering or the processing industry.
The GEMÜ Code 5T diaphragm is available in diaphragm sizes 10 to 100 and has a threaded pin that is sintered into place with integrated screw-in stop.
