A mechanical seal is a method of containing fluid within a vessel such as pumps
where a rotating shaft passes. It is used to address the challenge of supporting a shaft to operate in the wet area of a pump without allowing a large volume of pressure to get lost. Seals
are made of several parts. One, the stationary section that is fitted to the pump housing using a static seal that is gasket clamped between the pump housing and the stationary section. The second section is the rotary part of the seal. This part is sealed into the shaft using an O ring. The sealing point can also be considered static because it rotates together with the shaft. The third part can be either rotary or static and is spring-loaded to accommodate minor shaft deflections.For your seal to operate effectively, it is important to maintain a thin fluid film that serves as a lubricant. This thin film is mainly supplied by the fluid being pumped, although it can also be supplied from an external source.
