Diaphragms are used in the process industry, for example in drives, fittings, hydraulic accumulators, pumps, compressors, valves and controllers. The job of a diaphragm is to control, pump or separate products.
Sealing Technologies has played an important role in the emergence of the membrane industry and, thanks to more than 50 years of experience, has become the European market leader in Diaphragms. They offer the highest quality and for almost any application. They also offer solutions for a large number of flight systems, for example for engine controls, fuel supply systems, for valves and regulators in cabin pressure compensation, but also for emergency systems and for extra oxygen masks. We have a wide range of membranes especially for the aerospace industry, such as for rotary-wing and fixed-wing aircraft.
Sealing Technologies has decades of experience in the development and production of elastomeric diaphragms with fabric reinforcement, various inserts and PTFE film overlays. We provide extensive design support, including simulation capabilities (FEA) and testing facilities, to develop high quality and reliable diaphragms for custom applications. The company uses many different materials. Diaphragms made of elastomeric material facilitate the production of special seals for each industrial factor. They reliably and safely perform the following functions: pumping, regulating and switching, collecting and disconnecting. Materials meet industry-specific application standards and are OEM approved.
We offer a wide range made from a range of different materials, in both standard and custom sizes and formats. The full range of Diaphragms, including product and material data sheets, ordering options, prices and availability can be found on our website.
