1. Reliable seal, in a long period of mechanical seal will not leak or rarely leak. Clean, no dead space, can prevent the contamination of miscellaneous bacteria.

2. Long service life, the correct mechanical seal standard choice friction load ratio of mechanical seal can be used for 2 to 5 years, the longest useful to 9 years.

3. Long maintenance period, no maintenance is needed under normal working conditions.

4. No wear on shaft or sleeve.

5. Friction power consumption, generally about 10 ~ 50% of the packing box seal

6. Mechanical seal on the accuracy and smoothness of the shaft is not as strict as packing box requirements, the rotating reaction kettle mechanical seal shaft pendulum and shaft on the shell hole deflection is not sensitive, the vibration sensitivity of the shaft is small.

7. Wide range of application, can be used for low temperature, high temperature, high vacuum, high pressure, all kinds of speed as well as corrosive, abrasive, flammable, explosive, toxic media seal.
