Many construction projects have connecting and rotating shafts that usually use seals. Plenty of construction engineers have long recommended the use of mechanical seals in securing machines that have rotating shafts and parts. They provide stable, durable connections between moving parts.

Other alternatives can also be used but most of them do not really provide the convenience and cost-efficiency that a seal gives you. But if you are budget conscious and won’t mind the constant check-ups and maintenance, then you can always find gaskets, gland packing and other similar gasket type sufficient for your project’s needs.

How a Seal works

Mechanical seals provide support to connecting parts of a machine or installation. They join parts together and keeps what is flowing within securely inside. A normal seal is usually composed of a sealing face that is made form soft material that will be in contact with the hard material that it will connect. This sealing face will wear out in time, depending on how strongly the mechanical seal was made.

Most seals are also lubricated so it will be easier for them to be installed. This also means that seals normally come with oil feed line and oil scavenge line. The scavenge line can usually be found at the bottom of the seal housing. These parts should be checked regularly as they indicate whether the seal needs replacing or is still functioning properly.

Things to Remember When Installing Mechanical Industrial Seals

While it is definitely not a complicated task at all to install a seal in your machines, it may be good to keep in mind that careless installation of seals can have dire consequences. Some of the biggest problems you may encounter are leaks as well as the fast deterioration of your mechanical seal.

Seal manufacturers usually put specific installation instructions in their products for their clients’ perusal. You need to read these instruction manuals carefully so you can see the specifications of the particular set of mechanical seals you are buying. Some of them may not work reliably in extreme temperatures or they may require a certain set of oil for you to properly use.

When it comes to oiling your seals, some manufacturers recommend the use of petroleum jelly before you install the mechanical seal. Others suggest using compressor oil or some light mineral oil. Using lubricants will make it easier for you to slide the rubber-sealing boot into the shaft when using and it also helps in bonding the seal to the shaft easily.
