Utilize a static secondary seal, such as a metal or elastomer bellows. They eliminate shaft fretting and are ideal for extreme temperature ranges. Common Face Material Combinations The seal faces are pressed together by a

Excellent for water, steam, and polar solvents, but fails immediately in petroleum oils.

The seal faces are pressed together by a combination of hydraulic pressure from the sealed fluid and mechanical force (usually springs or bellows). A very thin fluid film (liquid or gas) forms between the faces, acting as a lubricant to prevent dry running [2]. B. The Three Essential Components and hydraulic balance

Alan O. Lebeck's "Principles and Design of Mechanical Face Seals" is widely recognized as a seminal technical text for understanding the fundamentals, design, and material selection of sealing technology. The text covers essential topics including face materials, thermal management, and hydraulic balance, with digital versions sometimes available via academic repositories.
