Mechanical seals are extremely important in a machine and/or pump. The seals prevent leakage which can cause damage to a pump. There are primary and secondary seals which consist of other types of seals. Priest Electric is a great source to find out which seal is correct for your pump.
The primary mechanical seal consists of a stationary seal and a rotating seal. These seals are extremely flat and "rub" together, lapped within two light bands. Together these seals prevent leakage because of their flatness and are 85 light bands to one thousandth of an inch. There may be some very minor leakage between these faces however it appears as a vapor.
