Let's look at some of the common reasons why mechanical seals fail - and help you protect your seals and them and make them last longer.
1) Letting the pump or machine run dry: A mechanical seal can easily leak or become damaged if you let your pump or machine run dry. If the seals run dry, the friction will cause heat to accumulate, and cause damage - causing thermal shock. Your seal can disintegrate just 30 seconds after heating up!
2) Too much vibration: Pump vibration can be caused by improper alignment, pump imbalance or operating the pump past its BEP (best efficiency point) - which means it's operating beyond its normal working point. These vibrations damage the machine and lead to reduced seal life
3) Hammering couplings: Many machines contain components like pistons that have a hammering action, sometimes so intense that it produces a lot of vibration and movement. This can cause problems not only for the machine but also for the seals.
4) Human error: Simple human mistakes can cause the seals to fail. For example, not starting the machine up properly can cause the motor to trip and the shaft to twist, causing movement that results in internal parts coming into contact, seal failure, and even reduce the life of bearings. Other human errors that can cause seals to fail include improper installation of the seal, failing to clean the areas surrounding the seal, and lack of proper maintenance. Oil, dirt and even fingerprints can damage the seal, so it's important to exercise due diligence when it comes to seal care!
5) Using the wrong seal: It's important to find the right seal for the job, which means selecting the appropriate seal for the machine that you're using. However, even seasoned engineers can get it wrong, which leads to errors during installations. Different machines or pumps require different types of seals and are built to handle different materials. Using a abrasive material can also reduce the lifespan of a seal.
