Diaphragm

PTFE Composite Diaphragm

PTFE composite diaphragms are used everywhere where toxic and chemically aggressive agents are conveyed. Through the patented PTFE diaphragm surface structure „SOF“, our diaphragms can reach high load cycles and a high service life even if these are highly loaded. PTFE foil satisfies the FDA requirements and is therefore appropriate for the usage in the food sector.


PTFE composite diaphragms have a PTFE foil film that is fixed on the elastomer surface towards the media side. The PTFE foil forms a closed surface. It is resistant to almost all chemical agents. The chemical resistance range goes from pH 0 to pH 14.


In order to fulfil the high resistance requirements, PTFE composite diaphragms are usually equipped with a fabric reinforcement. The supporting plates or clamping plates can also be integrated into the diaphragm, to avoid dead space and support cleaning and sterilization.  


In our production process, composite diaphragms are manufactured based on individual components and they can be varied according to the customer’s need.
