Type 1604

Manufacturer: John Crane

Single Stationary API 682/ISO 21049 Metal Bellows Cartridge Seal Type C, Arrangement 1

The Type 1604 high temperature, high performance Type C, Arrangement 1, API 682/ISO 21049 qualified cartridge seal is designed for high temperature applications such as hot hydrocarbons and crude oil fractionation products. The Type 1604 utilizes a stationary Inconel 718 welded metal bellows with flexible carbon graphite secondary seals. The stationary mounted metal bellows seal is able to handle higher shaft speeds. The Type 1604 utilizes a segmented spring loaded carbon throttle bushing for effective containment and can come equipped with a retained mating ring for vacuum service. The Type 1604 is often supported by an API Plan 62 quench (steam) and a steam guide for effectively routing of the steam to the seal faces to help eliminate any coke build up that could occur when sealing hot hydrocarbons.
