SES 100 Series

Cantilever Spring Energized Seals (SES) are primarily used in highly dynamic applications for rotary and reciprocating equipment, but they can also be used in static applications, when higher deflection springs are needed. The improved spring and seal deflection capability can be required due to excessive expansion or contraction or wide hardware tolerance.

The 100 Series incorporates a U-shaped seal jacket with a high performance, stainless steel V-shaped cantilever spring to apply positive sealing force to the mating surface.

This design utilizes an asymmetric seal profile, where the dynamic lip has a robust profile in combination with a front angle, providing excellent leakage control and good scraping effect in case of highly viscous medias. The V-shaped cantilever spring design provides the spring tension at the leading edge of the seal only, which helps to optimize lip load and minimize frictional force.

Seal jackets are made from high performance fluoroplastic compounds and engineered plastics that provide, low coefficient of friction, high abrasion resistance, dimensional stability, and outstanding resistance to most fluids, chemicals, and gases.

This is the most popular spring energized seal design series due to its unique attributes, which help to maximize seal and hardware life.

The 100 Series is available in different unique jacket materials to address a broad range of applications.
