Diaphragms Flat Diaphragms

Flat diaphragms are flat, elastic diaphragms that are used primarily in applications with very small strokes. Thanks to their simple and space-saving design, they can be integrated into a variety of technical systems.

Depending on the requirements, flat diaphragms can be manufactured from various elastomer materials and reinforced with a suitable fabric. This allows for different requirements regarding load-bearing capacity, media resistance, and service life to be met.

What are the advantages of flat diaphragms?

  • Compact design – The flat geometry allows for a low profile and facilitates integration in spaces with limited installation room.
  • Suitable for very small strokes – The design is particularly well-suited for applications with short travel distances.
  • Cost-effective manufacturing – The simple geometry allows for comparatively cost-effective production.
  • Various designs available – Depending on requirements, different elastomer materials and, if necessary, fabric reinforcements can be used

Where are flat diaphragms used?

Flat diaphragms are primarily used in applications with very small strokes. Due to their low profile, they are also suitable for designs with limited installation space.

Typical areas of application include, for example:

  • Measurement and control technology
  • Diaphragm gas pumps with vacuum
  • Control technology
  • Pneumatic and hydraulic applications
  • Pressure transmission applications
  • Compact technical assemblies

The specific design depends on the requirements of the respective application.

Designs and Materials

Flat diaphragms can be manufactured from various elastomer materials. Depending on the requirements, suitable fabric reinforcements can be used.

Factors considered during selection include the medium used, temperature, pressure, required flexibility, and desired service life.
