The Zook SFAZ Bursting Disc (rupture discs) is a solid metal scored disc design. They are designed to be used specifically in the UHZ Holder. The Zook SFAZ Bursting Disc incorporates a Fail-Safe Design. If the SFAZ Series Disc is damaged or incorrectly installed, it will always burst at or below the marked burst rating as indicated on the disc tag.
- Non-fragmenting solid metal cross scored disc is scored on the vent side to minimize the effect of product build-up
- Operating pressures up to 90% of marked burst pressure
- Flat seat design
- ASME UD marking available (Gas service only)
- Solid metal scored disc designed for Non-fragmentation
- Excellent for liquid, gas or 2-phase flow
- Scored after disc material is formed to a high crown height. Permits use of thicker material and allows lower burst ratings which withstand full vacuum
- Burst ratings 15 to 3600 psig
- Sizes 1/29thru 249diameters
- Temperature ratings to 1000°F (538°C)
- Standard material of construction is Nickel. Optional materials 316SS, Inconel, Monel, Hastelloy C and Aluminum are available
- 3-dimensional stainless steel tag permanently engraved with complete disc specifications
- ASME UD marking available (gas service only) Polymerization Vessel Protection
- Withstands corrosive attack
- Positive-to-negative cycling
- Higher operating ratio
- Use alone or combine with relief valves

Technical Data
- Engineered Polymer Composite Construction offers cost-effective corrosion-resistance, is lightweight, non-galling, non-sparking, and non-conductive.
- Unitized Case with Integrally Molded Flanges at the suction and discharge nozzles, fully gusseted for structural soundness.
- Externally Adjustable, Semi-Open Impeller provides consistently high efficiencies and minimizes maintenance.
- Shaft/Bearing System operates below the first critical speed for less shaft whip and longer bearing life.
- Bearings can be lubricated by external flush or self-lubricated by the pump fluid.
- Single-Piece Column is lightweight, filament-wound, reinforced fiberglass composite for strength and rigidity.
Advantages
- Lightweight and corrosion-resistant due to engineered polymer composite construction.
- High efficiency and minimal maintenance with externally adjustable impeller.
- Long bearing life with low shaft whip and flexible lubrication options.
- Robust construction with unitized case and reinforced single-piece column.
