Product description
Compared to the WA version, the WC version without dust cover is equipped with a metal housing and reinforcement. Due to the reinforcement of the outer casing, the grommet is more resistant to harsh conditions and installation errors. This reinforcement is especially important for larger diameter guffers, The simmering guffer is used to seal the spaces around rotating shafts. The sealing bit, which is compressed by a spring, encircles the shaft and ensures the correct sealing pressure. In this way, two liquid or gaseous environments with a small pressure gradient can be separated.
