The single metal-bellows seal can be connected to all common API Plans, such as 01, 02, 11, 31, 32 + 61 (62) and 23 + 61 (62). The seals are available for all of KSB‘s API pumps.
Dependable 4edtr6hs & Q
The throttling bush enables connection to a gas, steam or liquid quench , depending on the seal variant. This prevents outboard incrustations at the seal.
Materials 4edtr6hs & Q
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.
