Concurrent qualities and advantages of CARLIFE 99/99SS™ Structure.
The CARLIFE 99SSQ™ is quite similar to the CARLIFE 99SS™, with the addition of a Quench port and an internal bushing, which will increase the overall length of the seal slightly. This is the result of a unique concept of integrating the constant temperature features with the gland to promote maintenance convenience, because the constant temperature feature might not need to be disassembled during maintenance.
Simply by injecting steam into the seal via the Quench port, it cans help maintain the internal temperature of the seal, self cleaning and act as a barrier keeping possible contaminants intruded into seal face from the atmosphere side, and blowing off the crystallization or particles of educts on the seal rings surface from process side, that enables to increase the stability of mating face. The addition of the Quench port feature is especially beneficial for the application, which requires constant temperature control to prevent crystallization.
