    Extrusion Burst Plugs

    Extrusion Burst Plugs (bursting discs) are pressure relief devices designed for over-pressure protection of plastic extrusion processes.


    • Each EBP assembly consists of a threaded tubular body with a rupture disk welded onto the process end
    • ZOOK has the ability to supply any specific combinations of dimensions, threading, and body configuration
    • The EBP assembly is mounted directly into the extruder equipment through a pressure port or thermocouple-well where critical pressures are experienced
    • Body materials: 304 series Stainless Steel with other materials available on request
    • Standard rupture disk material: Inconel
    • Stocked burst ratings 1,000 psig to 15,000 psig in 500 psi increments (for higher pressures contact ZOOK)
    • 0% manufacturing range
    • Burst tolerance ± 10% with typical standard deviation of ± 1% throughout the temp range of 300°F to 750°F (149°C to 399°C)
    • Standard EBPs in stock
    • Customized designs available
    • 100% factory leak-tested
    • 100% electronic thread verification of every assembly utilizing digital imaging

    ZAM Plus Rupture Disk Alarm Sensors

    The ZAM Plus Rupture Disk Alarm Sensors have a surface mounted monitor designed to remotely detect the condition of a rupture disk (bursting disc) in service. Used in conjunction with the ZOOK ZENSOR®, BA, RDI, BI or similar devices, it will immediately warn the operator of a ruptured disk. The alarm system uses a normally closed electrical circuit. When the disk ruptures, it breaks the circuit, triggering the alarm. The ZOOK ZAM alarm system is capable of detecting a ruptured disk condition in applications involving highly electrically conductive fluids.

    Rupture Disk Alarm Sensors Features:

    • Intrinsically safe output for Class I, II, and III, Division 1, Groups A, B, C, D, E, F, and G hazardous locations
    • Utilizes FM approved, PED and CSA compliant I.S. barrier
    • Enclosure: NEMA Ty[e 12, constructed of 14 gauge steel with continuously welded seams and oil resistant seals
    • Provides an audio/visual signal and an output relay for each channel; the channel will automatically reset once the burst indicating device is replaced or reset
    • The audio alarm can be silenced with a push button switch
    • Contains front panel push buttons for testing each channel; this function can also be performed remotely
    • Field replaceable I.S. barrier module and power supply
