The Hook / Sleeve type metal bellow seal is a semi-cartridge or cartridge-adaptable seal where the sleeve/hook assembly provides the primary drive and support for the bellows.
This enables easy installation, good alignment, and better handling of mechanical loads.
These seals are mostly use in KSB and Jhonson pumps, requiring robustness under high temperature, varying pressure, or when maintenance and installation ease are priorities.
