NVS-2 is a dry-running carbon floating ring seal, mainly consisting of an integral end cover, a shaft sleeve, and seal rings. The seal rings feature a multiple spring design on the sealing faces, using both process pressure and spring force to achieve face contact and reduce leakage.The NVS-2 have self-adjusting carbon rings ensure stable sealing performance during operation.Carbon floating ring seal solutions like NVS-2 are widely applied in compressors, turbines, and other rotating machinery.
