In the pharmaceutical industry, the most important concern is safety, so the mechanical seal used must ensure health and safety. Secondly, as the key equipment in the pharmaceutical production process, regular maintenance will inevitably lead to many additional cycles. Therefore, the service cycle of the mechanical seal is also an important link for customers to consider.

　　The following are the advantages of mechanical seals in use:

　　1. Reliable sealing: in the long cycle operation, the sealing state is very stable, and the leakage is very small. According to rough statistics, the leakage is generally only 1/100 of that of soft packing.

　　2. Long service life: generally one to two years or more, it can also reach more than half a year in chemical medium.

　　3. Low friction power consumption: the friction power of mechanical seal is only 10% - 50% of that of soft packing seal.

　　4. The shaft or sleeve is basically free from friction.

　　5. Long maintenance cycle: after the end face is worn, it can be automatically compensated. Generally, there is no need for regular maintenance.

　　6. Good vibration resistance: insensitive to vibration and deflection of rotating shaft and deflection of shaft to sealing chamber.

　　7. Wide scope of application: mechanical seals can be used at low temperature, high temperature, vacuum, high pressure and different speeds; And the sealing of various corrosive media and media containing abrasive particles.
