Different Types of Mechanical Seals and Perfect Scenarios to Use Them Most engineering projects will require the use of mechanical seals in almost every activity which might include laying pipelines and construction works. However many people find it quite a challenging task to select the best mechanical seal for a project and various factors must be considered in making a choice. In some cases, the project might state the recommended type of mechanical seal for the work. However, if there are no specifications, you must be conversant with the various types of gaskets, gland packing, and mechanical seals. If you do not know how to make the right choice for your construction project, you can find assistance from seal manufacturers and suppliers. The manufacturers and suppliers might have the good will of helping to select the best mechanical seal, but the seals might not be appropriate for your project because they do not have the details of the project. You are the one who understands that project, and therefore, you have a duty to identify what types of mechanical seals are appropriate and to do this you will require some basic information about types of seals and their use. There exist various types of seals that you can select for your project. Most engineers use the hydraulically balanced seal. The main advantage of using this seal is that it generates less heat and it can also handle high pressure when in use. Before you settle for the type of seal you need to evaluate and estimate the amount of pressure in the pipe or machines and if it is over 400 pounds per square inch, then it is the most recommended one.

The stationary seal is also another type of seal which is most suitable for projects with misaligned connecting machines. For instance, a pump and its driver or a stuffing box that does match its rotating shaft. This type of seal works well when you have a pump that operates at a great speed.

Heat production is common in some projects, or some projects must be carried out under high-temperature environment and the best mechanical seal to use is the metal bellow seal. They might not only be useful in high-temperature areas, but they can also be helpful in conditions of extremely low temperatures. In machines that have two way systems, it is recommended to use dual mechanical seals. The seals can be used for emergencies such as shutdowns or power outages. Non-metallic seals are useful in connecting non-metallic parts. They work correctly in sealing gases and liquids in pipes. These types of mechanical seal are less costly compared to metallic ones, and they are available in most stores.
