Flexible separators are used, among other things, in hydraulic systems and large transformers. They separate working media such as hydraulic and cooling fluids hermetically from surrounding foreign media and balance out level changes in the storage tank. The working media are protected from contamination, moisture and oxidation, which leads not only to an increased service life of the working media, but also to less environmental pollution.
Use underwater is also possible. Flexible separators are made of different materials or material combinations (fabric-reinforced elastomers and/or polyurethane) in dependence on the application and media. Various connections, fastenings and geometries – adapted to the conditions – are possible.
