The lifespan of a mechanical seal varies depending on operating conditions and type:
Generally speaking:
Water, oil, and similar media: With proper selection, installation, and proper use, a mechanical seal's service life is generally at least one year.
Corrosive media: Under the same conditions, a mechanical seal's service life is generally between six months and one year.
Specific types:
Welded metal corrugated tube mechanical seals: With proper selection, installation, and proper use, and with the system functioning well and the equipment operating stably, the service life is at least 8,000 hours. Exceptions may apply to special operating conditions.
Industry standards:
API 682: The American Petroleum Institute's standard for mechanical seals in petroleum and chemical pumps stipulates that mechanical seals should be able to operate continuously for 25,000 hours without replacement.
Note: The above data is for reference only. The actual service life may be affected by many factors, including the operating environment of the seal chamber, the technical specifications of the seal, and the quality of the pump. To extend the service life of a mechanical seal, it is important to establish a suitable operating environment, meet the technical specifications of the seal, and use a high-quality pump system.
