The Various Types of Mechanical Seals

When we are talking about mechanical seals, it is not possible to go on without mentioning the different categories. There are slightly variations which are not visible to amateurs. Various agitator seals and mechanical seals are now provided by manufacturers but what is the difference?

It is not easy to determine what you are looking for so identifying the difference will be useful.

Types of Mechanical Seals

If you want to learn about the varying types of mechanical seals or agitator seals that are available, keep reading. This comprehensive list will explain what makes one different from the other and which one to get:

Pusher & Non-Pusher

The major types of the mechanical seals are pusher and non-pusher seals. The pusher mechanical seals usually have a mounted spring which is placed on the shaft. It plays an important role in applying force to the seal. On the other hand, a non-pusher seal uses bellows as an alternative to the springs.

Both types of mechanical seals that fall under this category are affordable and not very complex to use. They are also equipped with the tolerance level for vibration of the pump without wearing out.

Balanced & Unbalanced

Another widely known category of the mechanical seals is the balanced and unbalanced. The balanced mechanical seals provide high level of pressure. They can be used for fluids that don’t have lubrication qualities. Whereas, the unbalanced mechanical seals are the opposite and they can also tolerate the high vibration. Even in case of pump misalignment, unbalanced mechanical seals work fine.

Conventional

While talking about the various types of mechanical seals the information would be incomplete without conventional ones. These types of seals are usually better when they are attached as lip seals. Most of the types conventional mechanical seals are seen and treated as extension of the compressors or pumps. They are require a certain level of maintenance to work well.

Cartridge

The last type is the cartridge mechanical seals which come in a package which is suitable for industries that require heavy duty seals. These types of seals are ideal as they will protect the shaft and housing both. This type of premium sealing option enhances their workability and efficiency in the oil industry. These days, most people are using the cartridge mechanical seals on their latest pumps to make sure that both of the components will work for the longest time.
