Benefits

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.

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.

Variant 4EDTR6HS

Single metal-bellows seal with floating throttling bush foroptional connection to a gas quench or steam quench.

Variant 4EDTR6HQ

Single metal-bellows seal with segmented throttling bush for
use with a liquid quench.
