The function of the sealing elements is to prevent the mixing of fluids in two separate environments and to keep the amount of fluid constant throughout the life of the sealing element. Sealing elements are divided into two main groups as static sealing and dynamic sealing elements according to the function mechanism.
The importance of seals, which are basically perceived as having a simple function, is high because it will protect other machine parts. Sealing elements; differs from each other by the elastomer material mixture, physical and chemical properties, tolerances, and sealing geometries of the materials. Management of the effects of these features on the sealing mechanism requires a great deal of knowledge and engineering.
FEKO has established its own standards and proved its quality with the knowledge developed since 1972, the referenced standards and technical staff. In this sense, it continues product development activities with customer-specific designs relying on advanced laboratory, test facilities and experienced engineer personnel.
Based on the incompressibility and elastic modulus properties of the elastomeric material and the pressing share of the sealing element, the pressure applied by the sealing element to the contact surface provided the result that is the sealing which always is higher than the pressure of the fluid.
It is the sealing formed as a result of the hydrodynamic effects in the thin film layer formed in the part where the sealing elements working on the moving surfaces touch this surface.
