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.
