Industry Information

Mechanical Seals

Mechanical seals are used to prevent leakage in various mechanisms, including agitators, mixers, gas seals, and pumps. In addition to preventing leaks, mechanical seals also keep contaminants from entering and help to maintain pressure levels. Mechanical seals are intended for applications in which a rotating shaft and its housing are under a state of extreme stress, including a combination of high pressure, temperature, and speed.

Most mechanical seals are specially designed to prevent leaks in particular applications and cannot be interchanged with those seals used in other mechanisms. Mechanical seals may be either single spring or double spring designs. They can be ordered in a variety of designs, sizes, and materials.
