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 mechanical 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 mechanical seals needs replacing or is still functioning properly.
Basics of fluid pump sealing
A mechanical seal is simply a method of containing fluid within a vessel (typically pumps, mixers, etc.) where a rotating shaft passes through a stationary housing or occasionally, where the housing rotates around the shaft.
