How long should my mechanical seal last?
A mechanical seal will hardly ever fail due to age, but rather through the seal faces wearing excessively. As mechanical seals are used in a variety of applications and industries, giving an exact life span is nearly impossible, as the pressure, temperature, abrasiveness, toxicity, and consistency of the material being sealed will impact the level of wear and tear on the seal facing. The only accurate way of predicting this would be to consult the functional duration of a mechanical seal which is equipped in the same function as your seal.
How do I know if my mechanical seal has failed?
A mechanical seal has failed if it has excessive leakage and is unable to seal the material effectively any longer. A way to see this is if the seal is unable to maintain the desired pressure within the materials it needs to seal. Additional ways to identify if your mechanical seal has failed are to identify if there are any notches or scratches on the surface face of the seal or if there are any cracks, if there is uneven wear and tear, if the seal is emitting a squeaking noise, or if the O ring or rubber seal ring is damaged.
How much should my mechanical seal leak?
A small amount of leakage from a mechanical seal is normal. Mechanical seals work by having a small gap between the faces in order to allow for lubrication, preventing friction between the faces and wear and tear. This gap is calculated to be large enough to allow for this lubrication, whilst being small enough to prevent large amounts of leakage. The amount of leakage acceptable depends on the application of your mechanical seal, and how hazardous the material itself is.
Why do mechanical seals get damaged?
Mechanical seals can be damaged due to a variety of factors. The most common source of damage is through general wear and tear of the seal faces, often caused by improper installation or the pressure of the material the seal is holding. Another source of damage is through general corrosion of the mechanical seal, if the material being sealed is hazardous.
