1. the seal is reliable, so that the mechanical seal will not leak or rarely leak in a longer service life. Clean, no dead corner, can prevent the contamination of bacteria.

2. Long service life, correct mechanical seal standard selection friction load specific pressure mechanical seal can be used for 2-5 years, the longest useful to 9 years.

3. the maintenance cycle is long, under normal working conditions, there is no need for maintenance.

4. Shaft or sleeve shall not be abraded.

5. Friction power loss is less, generally about 10-50% of packing box seal.

6. Mechanical seals are not as strict as filler box requirements for the accuracy and smoothness of the shaft. They are insensitive to the oscillation of the rotating shaft of the mechanical seal of the rotary reactor and the deflection of the shaft to the shell hole, and are less sensitive to the vibration of the shaft.

It can be used for sealing of low temperature, high temperature, high vacuum, high pressure, various rotational speeds, corrosive, abrasive, flammable, explosive and toxic media.
