14 – Reducing Mechanical Seal Failures.

We continue to delve into the benefits of oil mist lubrication in improving the reliability of mechanical seals.

Here Heinz Bloch explains that the root cause of mechanical seal failure is sometimes misdiagnosed. When a failure is verified in a centrifugal pump and it is inspected and the mechanical seal is found to be damaged, it is determined that the root cause has been the mechanical seal; when sometimes, the true root cause has been poor lubrication in bearings, which manifested itself with a break in the mechanical seal, as this element is a kind of fuse.

It is enough to observe the recommendation of API 751 that deals with Safe Operation in Alkylation Plants; where it is recommended to use oil mist lubrication to reduce the risks of having mechanical seal failures, which cause dangerous emissions to the environment.

We can then conclude with these last two posts, that the application of oil mist lubrication will achieve a benefit in terms of reducing failures originally attributed to mechanical seals.

13 – Failure Reduction by Mechanical Seals

Here Heinz Bloch shows us a comparison of MTBF only of Mechanical Seals, for two similar Plants, one with conventional lubrication and another with Oil Mist lubrication.

But how is it possible that the application of oil mist produces benefits in reducing mechanical seal failures, if they are not exposed to oil mist lubrication? In our Company we have many experiences of introducing mist lubrication, and receiving the same feedback from the client, indicating that they do not have problems with bearings, but they do have problems with mechanical seals.

In this video fragment we will only mention that both the mechanical seal and the bearings are mounted on the same shaft; and that any improvement that we can apply to the bearing will influence the mechanical seal.

In a future video, we will explain this topic in more detail.

12 – Pump Repairs.

This fragment shows in more detail the reduction in failures when mist lubrication is applied. Two similar plants with about 200 pumps each are compared. In one plant, the conventional oil bath lubrication method is used, and in another plant, mist lubrication is used. The number of repairs is much lower in the plant where mist lubrication is used. The reduction is approximately 90%, without a doubt, a very important benefit.
