Mechanical Seals
6000 Series
Rotating Metal Bellows Seals
Single and dual cartridge rotating metal bellows seals with no dynamic O-rings, built for the toughest operating conditions in refineries, petrochemical plants, and chemical plants, including high temperature service to 750°F.
Built for the Toughest Operating Conditions
The FSI 6030/6040 seal line is a hearty single cartridge rotating metal bellows seal, designed for handling even the toughest operating conditions in refineries, petrochemical plants, and chemical plants.
The FSI 6080 is a double cartridge rotary metal bellows seal, double balanced to provide both pressurized and non-pressurized seal operation. The type 6090 seal is a heat-treated high temperature rotating metal bellows design, available as either a component seal or a cartridge mounted assembly.
Across the 6000 Series, all O-rings are static. Centralized face loading keeps the faces flat throughout all temperature and pressure ranges, and the rotating bellows design is self-cleaning through rotational expulsion of particulates.
* As always, consult your ASI representative for applications which approach or exceed these parameters.
Three Metal Bellows Designs
A hearty single cartridge rotating metal bellows seal, designed for handling even the toughest operating conditions in refineries, petrochemical plants, and chemical plants.
- Inherently and hydraulically balanced
- Centralized face loading ensures even face loading (flatness) throughout all temperature and pressure ranges
- Tangential porting to maximize flush effectiveness
- All O-rings are static; no dynamic O-rings
- Rotating bellows design is self-cleaning, through rotational expulsion of particulates
- The 6040 is provided with quench and drain ports as standard. Options include restriction bushing, lip seal, or die formed graphite ring containment system.
A double cartridge rotary metal bellows seal, double balanced to provide both pressurized and non-pressurized seal operation. FSI 6080 seals are sturdy and versatile.
- Incorporates radial flow pumping ring for positive circulation
- All O-rings are static; no dynamic O-rings
- Two-piece gland allows for economical bi-metal construction
- Centralized face loading ensures even face loading (flatness) throughout all temperature and pressure ranges
- Available in all ANSI pump sizes for both standard bore and oversize stuffing box configurations
A heat-treated high temperature rotating metal bellows design. Available as either a component seal or a cartridge mounted assembly, with the same inherent features as our other metal bellows seals.
- AM 350 SS or Inconel 718 bellows
- Graphoil secondary seals for high temperature service
- Flush, quench, and drain gland available with carbon or bronze restriction bushing
- Available steam purge bushing for hot hydrocarbon services
- Face materials of carbon, silicon carbide, and tungsten carbide
