Simple seal structure, easy to manufacture and install. When installing, just put the sealing accessories into the sealing slot and then gently press them to seal. At the same time, the seal has a good self-adjustment function, which can adapt to different sizes and improve production efficiency. Due to the simple sealing style and relatively few internal structures, the chance of sealing leakage is reduced, the long-term and stable use of seals can be ensured, the service life of the machine is extended, and the maintenance cost is reduced.
Product Application
This mechanical seal consists of a pair of sealing end faces, which is the most commonly used mechanical seal type when the media itself has good lubricity and allows for minor leakage. It is commonly used for stirring shaft sealing and is an ideal way to solve stirring shaft sealing.
