Diaphragms
Diaphragms are sealing elements made of elastomer materials which form a sealing and yet flexible barrier between two component sections. This allows media to be separated, yet simultaneously to be converted into forcer through volume displacement.
The multi-functionality of our diaphragms allows the processing industry to cover a multitude of different functions. They can be used not only to operate valves, control and switch apparatus, to pump and compress liquids and gases, but also to separate or store media and pressures.
With our manufacturing expertise in all basic types of elastomer, including polyurethane, as well as in application-specific modification using fabric reinforcement, metal inserts or film facings, we offer an unusually media resistant and functionally reliable range of products. In addition to that, these can be used particularly cost-effectively, as the low requirements of tolerances and surface qualities of the neighboring components allows low-cost production of these parts.
A summary of the advantages
- Good media resistance
- Wide range of functions and applications
- Cost-effective, no maintenance required
- High functional reliability
- Numerous releases and approvals
Function
- Controlling and switching through pressure which is converted into rod loading
- Separating media in spaces with almost the same pressure level
- Pumping and compressing liquids and gases
- Measuring volume flows
- Operating valves

Application areas
As the shape and composition of diaphragms can be developed very specifically for the individual application, the range of uses is correspondingly diverse. As a general rule, membranes are used in the drinks and food industry for the following applications:
- Actuators
- Valves and fittings
- Hydraulic accumulators
- Pumps
- Compressors
- Sanitary valves and fittings
- Valves and controllers
