Mechanical Seal

Mechanical seal is a mechanical device which is used to prevent the (leakage) liquid coming from inside casing to outside through between static and rotating parts. Mechanical seals are used in centrifugal pumps. There are many types of mechanical seals used in the many equipment’s. It is classified on the basis of design, working, and arrangement.

The seal face is the most important part of the seal. Because the face material is the most expensive part of the seal and that creates a seal between static and a rotating part of the equipment. The description of types of the mechanical seal below.

Types Of Seal

There are two types of seal

It is a mechanical device that is used to transfer the fluid from one place to another place with the help of a rotating impeller. the rotating impeller converts kinetic energy to hydraulic energy with the help of pump casing. Centrifugal pump work on the principle of centrifugal force, when the impeller starts rotating, suck the fluid from the impeller eye it creates a centrifugal force which throws the fluid outward to pump casing where the speed of the fluid is very high due to speed the kinetic energy converts to hydraulic energy (pressure energy). The Centrifugal pump is driven by an electric motor or turbine.
