WHAT IS A MECHANICAL SEAL

A mechanical seal is a method of containing fluid within a vessel (typically pumps) where a rotating shaft passes through a stationary housing or occasionally, where the housing rotates around the shaft.

When sealing a centrifugal pump, it’s essential to allow a rotating shaft to enter the ‘wet’ area of the pump, without allowing for pressurized fluid to escape.For this problem, there needs to be a seal between the shaft and the pump housing that can contain the pressure of the process being pumped and withstand the friction caused by the shaft rotating.
