split mechanical seal

A mechanical seal is a device used to contain fluid within a vessel where a rotating shaft passes through housing, or sometimes where housing rotates around a shaft. These vessels are usually pumps, mixers, agitators, etc. The mechanical seal's purpose is to allow the shaft to rotate freely without allowing large amounts of fluid to escape.

28/06/  · Any mechanical seal (split or conventional) can develop a mysterious, premature leak for any number of reasons. Maybe the pump suffers a bout of cavitation-induced vibration. Maybe the pump runs dry and the seal overheats. Maybe a load of sediment or crystals passes through the pump and damages the seal faces.
