Advantages of mechanical seals



1. The seal is reliable, no leakage or very little leakage during a long service life. Clean, no dead spots, can prevent contamination with bacteria.

2. The service life is long, and the mechanical seal with the correct friction load ratio can be used for 2 to 5 years and the maximum usefulness is 9 years.

3. The maintenance cycle is long and does not require maintenance under normal working conditions.

4. The shaft or sleeve is not subject to wear.

5. Frictional power loss is low, generally about 10 to 50% of the stuffing box seal

6. The accuracy and smoothness of the mechanical seal on the shaft is not as stringent as the stuffing box. It is insensitive to the runout of the rotating shaft and the deflection of the shaft to the housing hole, and it is less sensitive to vibration of the shaft.

7. Wide application range, can be used for sealing at low temperature, high temperature, high vacuum, high pressure, various rotation speeds and corrosive, abrasive, flammable, explosive and toxic media.
