Zook PB Bursting Disc – Forward Acting

Process Equipment Zook

The Zook PB Bursting Disc mounts with the concave surface facing the process media. As pressure increases above the recommended operating pressure, the disc will bulge until it reaches the maximum tensile strength of the material and ruptures.

Operating pressures to 70% of the disc’s marked burst pressure
Seat Configuration: Angular 30°
Sizes 1/4″ thru 24″ diameters
Temperature ratings to 900°F (482°C)

Options:
Vacuum Supports are required for vacuum services. Vacuum supports are attached to the process side of the disc and allow the disc to support a full system vacuum.

Liners / Coatings Teflon liners are available to provide protection from corrosive media if required. Coatings are also available. Refer to (Table 1 in Spec Sheet) for maximum temperature ratings for disc, liner and coatings.

Protective Rings can be used with Zook PB Bursting Disc to provide stability and protection when thin materials and/or liners are used.

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.
