Model : CarLife 99SS Single Mechanical seal

Inheriting the features of the Carlife® 99 single cartridge mechanical seal, Carlife® 99SS is primarily designed for slurry, highly solid contents and highly viscous medium environments.

The CarLife 99SS mechanical seal is specifically designed to resist moderate process solids without the need for a flush. Through an advanced design of anti-clogging construction, the seal is capable of providing uninterrupted operation without hanging up due to impurities or abrasive solids. The innovative sub-cartridge design enables faster maintenance and repair than conventional cartridge seals. Fitting both enlarged bore and tapered bore seal chambers, the CarLife 99SS meets the latest design criteria set by the fluid sealing industry and followed by most main seal manufacturers.

In addition to similar construction and assembly procedure, the CarLife 99SS and MGS series have maximum interchangeability of parts. More shared parts mean simpler maintenance process and inventory management. As a result, our CarLife 99SS customers are able to stock fewer inventory parts and pay much lower maintenance and inventory holding costs. And the more CarLife 99SS products they use, the more benefits they can gain from their cost-effective CarLife 99SS seals.
