Mechanical Seals

INFO #01

A mechanical seal is a device that helps join systems or mechanisms together by preventing leakage (e.g. in a pumping system), containing pressure, or excluding contamination. The effectiveness of a seal is dependent on adhesion in the case of sealants and compression in the case of gaskets. The seals are installed in pumps in a wide range of industries including chemicals, water supply, paper production, food processing, and many other applications.

INFO #02

Mechanical seals have the purpose of preventing leakage of a fluid (liquid or gaseous) through the clearance between a shaft and the fluid container. (Fig.1) The main components of amechanical seal are the seal rings on which a mechanical force is acting, generated by springs orbellows , and an hydraulic force, generated by the process fluid pressure.
