How to Increase the Life of Mechanical Seal

1. Amazing Tips to Increase the Life of Mechanical Seals Pump seal manufacturers in India and designers are often asked how to extend the life of mechanical seals. Mechanical seals have to undergo a lot and they are quite crucial to the functioning of any pump. It is extremely important to understand the reasons why mechanical seals fail. Unless you know the reasons why mechanical seals fail in the first place, you will not come to know how you can extend their life. Reasons why mechanical seals fail The average lifespan of a mechanical seal is about three years; however, the lifespan might reduce because of a number of reasons. Mechanical seals fail due to their exposure to contamination, but that’s not the only reason behind their failure. They could also fail because of improper flushing plan selection or incorrect installation of the flushing system. One of the major reasons behind their failure is the outside design and operating conditions. Pump vibration can also cause the seal to fail apart from a sudden change in the properties of pumping fluid. If there is a sudden change in fluid properties such as pH vibration, suction pressure, solid concentration or fluid temperature, the seal might fail. Now let’s take a look at some of the tips you need to keep in mind to extend the life of mechanical seals of your rotary pump or electric barrel pump. - Proper Installation We have discussed about this earlier in this post as well. Proper installation helps reduce mechanical seal failure by about twenty percent. The sealing system must be taken into consideration as well. You may know that cartridge type mechanical seals are used quite a lot these days.

2. - Routine maintenance According to the manufacturers of Teflon bellow mechanical seal, you can extend the life of mechanical seals if you carry out regular maintenance. Make sure that the total indicated run out is not more than 0.003” at the mechanical seal area. The end play must be of maximum of 0.005”. Always check for shaft concentricity. - Bearing must be taken care of Bearing failure can lead to a lot of problems and hence they must not be overlooked. This is because when the bearing fails it can no longer support the rotating shaft. When this happens, the seal failure is just around the corner. - Air pocket in seal chamber Pump seal manufacturers in India poor startup procedure can result in air pocket. You can bleed some air from the chamber before the start. Self-vented pumps automatically fix this problem automatically. Keep the above tips in mind to extend the longevity of mechanical seal of your pump. For more information related to rotary pumps or mechanical seals, feel free to get in touch with us.
