Screen & Sock Sanitary Gaskets
In many upstream and downstream processes, it is sometimes necessary to perform an inline or in situ filtration step. It is usually designed to capture isolated particles created by moving parts of the system. Deterioration of valve diaphragms, pumps or seals can generate this type of particle.
Our screen gaskets are not used the same way as conventional filters, although they can be considered a filter. Conventional filters are built differently and have many layers to prevent particles to pass through, these can reach efficiencies of almost 100%.
Sock screens offer a greater soil collection capacity than standard flat screens. If the capacity of a standard flat in situ filters is not sufficient then the Sock screen is a good alternative.
Main features :
- Many screens and mesh available
- Materials : EPDM, FKM, Silicone, Steam-Flon®
During start-up, it can be used to protect pumps from large particles that accidentally fall into the system and are flushed out causing significant damage.
Filling needles can be equipped with a fine filter down to 10µm to capture anything that shouldn’t be there before the vial is sealed.
A particle comes in many different shapes. For example, a hair has a diameter of Ø 0,1 mm but the length can be centimetres long. If the hair arrives perpendicular to the screen it might pass a 100 mesh screen. With a conventional filter, the second or third layer will prevent the hair to pass. Retention’s of standard screens are calculated according to international standards using perfectly round glass spheres. Our screens are only one layer and therefore they cannot be considered the same as a filter. Each screen gasket has a high-performance gasket made out of one of the validated compounds that we use for our standard Sanitary Gaskets range.
Sock screen gasket are available in 150 mm (6in) and 50 mm (2in) lengths.
