Metal bellow seals are different than the common mechanical seals and other types in many ways. They are usually seals which incorporate a vessel that comes with spring or elastic characteristic. The necessity for adding this elastic is to offer high-range of capacity to deal with pressure produced by the compressor. The bellow simply assumes its neutral position as soon as the pressure is released. The metal bellow seals are simply useful for retaining the quality of the seal and its workability.
Choosing the Metal Bellow Seals
As useful as the metal bellow seals sound, it is still difficult to purchase them when you are crowded with plethora of options. You can keep in mind various things when you are browsing through metal bellow seals.
Installation
Different manufacturers of metal bellow seals offer differing installation options. Some can be difficult whereas others don’t take too much time and effort to install. An easy installation process will also mean that you can start using it as soon as possible.
Corrosion Resistant
Secondly, just like other mechanical seals, metal bellow seals are also vulnerable to damage. Usually, metal bellow seals are made from the highest quality of alloy. But, you should keep in mind that all types of metals can be exploited by dirt, chemicals and fluids that might cause corrosion and abrasion. Ultimately, if you are not purchasing high quality metal bellow seals, you will see untimely abrasion leading to the destruction of the seals.
Durability
Since you are going to spend your money on the product, it is best to look out for products which are made by durable and reliable manufacturers. Many of the metal seal manufacturers will provide you the estimation of the life of metal bellow seals. This information can help you determine whether or not you can trust particular mechanical seal with bellows or not.
Stick-Free
One of the essential properties of good metal bellow seals is that they are non-stick. If they do not have the capacity to deal with sticky fluids then they will eventually be damaged to a point of complete trip. A slip-free and non-stick metal bellow seal will go a long way to offer high level of efficiency and prevent any corrosion.
High-Pressure Reliance
Let’s admit the fact that the major reason for using metal bellow seals is their capability of withstanding high-pressure. However, a cheap quality seal will not give you the desired result and might not be able to tolerate when the pressure is high. You should ensure that you are buying a product that gives you the same level of resistance that it promise.
In other words, buying metal bellow seals or mechanical seals is not complicated if you do your research. If you make a smart purchase, you will reap the benefits for a long time. It is not easy to sift through so many metal bellow seals but you can easily narrow down your options by eliminating low quality products and manufacturers.
