Causes for Self-Destruction in Pump Seals

Since cartridge seals, dry gas seals and mechanical seals are so common these days it should be kept in mind that they are vulnerable to damage. Although they can be long lasting when used correctly, they also have a tendency to self-destruct under certain circumstances.

If you want to protect the pump seals and mechanical seals from damaging on their own you need to learn more. Particular factors play their role in damaging the seals and expiring them before time. So what are the factors?

Self-Destructing Phenomenon of Mechanical Seals

As you have learned that mechanical seals and pump seals can work towards their own annihilation, it is time to know about this in detail. Following are the reasons which cause the pump seals and other types to lose their reliability:

Hammering

One of the main reasons is the hammering on the shaft of pump which can eventually destroy the seal. Mechanical and pump seals are quite vulnerable and delicate compared to the harsh effects of hammering. If you hammer couplings on the shaft you will eventually notice that the seal has broken.

Dry Out

The second main reason for the destruction of pump seals and mechanical seals is the dryness of pump. This is due to a particular fact that seals especially mechanical seals can suffer the thermal shock. As a result, it might only take 30 seconds for the seal to completely break or shatter.

Operational Flaws

Something that many people don’t realize is the operation error which can result in destruction of pump seals or mechanical seals. Usually, this may happen if the start-up process has been skipped which might indicate an error on time. Therefore, never start the pump without ensuring the workability of mechanical seals.

You might notice things like tripping, twisting of the seals or completely failure which might either decrease the life or take toll on the quality of work. In addition, the improper installation also falls under the operation failures. Follow the instructions for installing pump seals and mechanical seals to avoid the damage. Sometimes, the smallest of things like dirt or fingerprints might spoil the seal.

Wrong Seals

As mentioned before, different seals are useful in different industries. Sizes, functions and characteristics can all determine whether particular pump seals and mechanical seals should be used in your machinery or not. When you pick a seal not made to work with your pump it will eventually deteriorate and self-destruct itself.

Pump Vibration

Pump vibration is a very common factor that results in damaging of the pump seals. When the pump is not arranged properly or it is even slightly out of position, it will cause the seal to penetrate and lose its integrity.

Flush Plan

And lastly, the pump must always coordinate with a flush plan for the exclusion of contamination and excess water. If a flush plan is not provided, it will result in the build-up of elements that can cause erosion of the seals and eventually complete breakage.
