NVS-5 is a dry running seal.This carbon floating ring seal.This carbon floating ring seal features a multi-part sealing ring design for reliable gas sealing. The rings are radially cut on the process side and overlap on the atmosphere side. Gastight mortised joints help maintain effective sealing between the ring segments.
The split housing design simplifies installation and replacement. No sealing components are mounted directly on the shaft. This structure avoids additional shaft vibrations caused by rotating seal components.
The floating seal rings maintain a very small operating gap around the shaft. This design helps achieve low leakage during operation. The seal also supports dry running without requiring a liquid sealing medium.
The self-adjusting seal rings accommodate radial shaft movements during operation. They also compensate for axial shaft movements. This capability helps maintain stable sealing performance under changing shaft conditions.
With a short axial installation length, the seal fits applications with limited installation space. The carbon floating ring seal is suitable for rotating equipment requiring low leakage and reliable gas sealing.
Can be used as a replacement for Burgmann WD200/500 type.
