What is a mechanical seal? Loughborough, Leicestershire, UK

A mechanical seal is a type of sealing device that creates a running seal between rotating and stationary parts. Mechanical seals have been developed to overcome the disadvantages of compression packing, offering little to no leakage of the product, reduced friction and power loss, lower maintenance costs, higher pressure sealing capabilities and the ability to function in more corrosive environments.

How do they work? Loughborough, Leicestershire, UK

The primary seal is achieved by two extremely flat, lapped faces which work together to create a difficult leakage path perpendicular to the shaft. Contact between these two surfaces ensures that leakage is kept to a minimum. True of all mechanical seals, one face remains stationary in a housing and the other face is fixed to, and rotates with the shaft. One of the faces is usually a non-galling material such as carbon-graphite. The other is usually a relatively hard material like silicon-carbide. Dissimilar materials are usually used for the stationary insert and the rotating seal ring face in order to prevent adhesion of the two faces. The softer face usually has the smaller mating surface and is commonly called the wear nose. The faces in a regular mechanical seal are lubricated with a boundary layer of gas or liquid between the faces. In designing seals for the desired leakage, seal life, and energy consumption, the designer must consider how the faces are to be lubricated and select from a number of modes of seal face lubrication.

To select the best seal design, it’s necessary to know as much as possible about the operating conditions and the product to be sealed. Complete information about the product and environment will allow selection of the best seal for the application.
