Elastomer Moulded Diaphragm

Diaphragm

 

We design and manufacture elastomer moulded diaphragms according to your needs up to a diameter of 550 mm’s.

Diaphragms are sealing components which seal two chambers hermetically, as elastically moveable partitions and whilst doing so, lead to a lifting movement that is perpendicular to the clamping surface.

They do not need any maintenance or lubrication, they are wear-free and have a long service life.
Thin-walled diaphragms operate almost frictionless without any breakaway torques.

Diaphragms are used in various technical ranges – the application determines size and design of the diaphragm.

Typical diaphragm designs are rolling diaphragms as well as crimped diaphragms, plate diaphragms, spherical diaphragms or flat gaskets.

In order to withstand higher pressures, to improve chemical resistance or achieve a longer service life, a composite diaphragm can be used for instance.

In our production process, composite diaphragms are manufactured based on individual components and they can be varied according to the customer’s need with or without:

  • fabric reinforcement,
  • foil coating and
  • plastic or metallic composite materials

We offer all common material combinations that are in compliance with KTW, FDA and W270.
