Benefits

The throttling bush enables connection to a gas, steam or liquid quench, depending on the seal variant. This prevents outboard incrustations at the seal.

The mechanical seal is available in a hard-soft combination of silicon carbide and carbon graphite, or in a hard-hard combination of silicon carbide and silicon carbide. The bellows made of Inconel® 718 and the secondary sealing elements made of pure graphite have an excellent chemical resistance and are especially suited for applications with high temperatures
