Diaphragms Diaphragm

Elastomer Diaphragms are sealing elements that act as flexible movable partitions providing hermetic sealing against two chambers. At the same time, they can perform a stroke movement that is perpendicular to the clamping plane. Diaphragms require no maintenance, no lubrication, they operate wear-free and have a long life performance. Thin-walled designed types run almost frictionless without breakaway torques.  

In our production, Diaphragms are constructed with single components and can be varied (according to customer specifications). For example with or without fabric reinforcement, foil lamination and metal core. We offer all established material combinations, if neeeded also with KTW, FDA and W270 compliance. Our technical consultants will gladly assist you in your product development.
