Cartridge version of Type 604 High Temperature Metal Bellows Seal

High Performance Stationary Seal 
The 1604 high performance cartridge seal is designed for difficult applications where high temperature products are being handled that tend to carbonise when coming into contact with atmosphere.

It is also stationary mounted a feature that allows the seal to additionally handle high speeds, thermal growth and shaft to seal chamber misalignment. The cartridge incorporates a steam flow guide that directs steam along the bore of the bellows past the face and out to drain.

This feature is very effective in cleaning any carbonised hydrocarbons from the bore of the seal and around the running faces in addition to cooling/ warming the process fluid making it easier to seal. In the standard cartridge this steam and any leakage is contained by a segmented carbon close clearance throttle bush.

For more toxic or flammable / explosive products the High Temperature Emission Containment Seal can be substituted for greater safety. Non standard options are double ply bellows for greater pressure capability and bellows strength. Replacement of the high temperature packing with O rings when more suitable for a particular application. The seal and seat are interchangeable allowing the cartridge to be converted from stationary to rotating bellows if considered to be necessary.

 

Design Features

High Performance edge welded metal bellows, Temperature range of -70 oC to 425 oC without the need to condition the process fluid, Speeds up to 50m/s, Pressures upto 25 Bar with a single ply bellows and 69 Bar with double ply bellows, Patented nested ripple bellows with 45 degree tilt angle for reduced stress and improved fatigue life. API 682 qualified seal. Stationary seal design with an option for conversion to rotating. Options of Carbon / Tungsten Carbide / Silicon Carbide faces. High Quality Silicon Carbide seats.
