PulseGuard Pulsation Dampeners End Plug Extractor Rigs

PulseGuard Pulsation Dampener Extractor Rigs PulseGuard pulsation dampeners of the following types shown on page 143, 144, 145, and 146 (the PipeHugger, PipeGuard, and PumpGuard ranges) have removable ends, generally in accordance with ASME VIII Div 1 UG34(m). The end plug lock ring retention is dimensioned to provide a safety release. It is necessary to withdraw these end plugs keeping the centerline axis of the plug true with the axis of the cylinder from which they are being withdrawn. If this care is omitted the cylinder bore may be scratched, preventing sealing with the replacement “O” ring. Never re-use an “O” ring. “Xtractor” Rigs for a straight withdrawal of end plugs Call factory for dimensions to make your own or to order / Xtractor XT1950 – up to units 450mm ID / Xtractor XT733 – up to units 285mm ID / Xtractor XT122 – up to units 150mm ID 1. After de-pressurization remove the bolts. 2. Remove unit from piping 3. bolt service block to system block 4. End plug slid / tapped in and lock ring removed 5. Half ring – A set is half the thickness of the units tamper-proof lock ring. The half ring fills the lock ring groove, and provides a smooth surface with chamfered corners to ease the slide-out of seals and membrane edges. Keep this half ring, to ease re-assembly. Half rings are individual to the ID of your unit and its pressure rating. Part number is your unit reference preceded by “HR”. 6. Half ring installed, xtractor attached 7. End plug being extracted by one turn of each nut repeatedly, provides a straight pull “Center Pull” - 5/8”UNC all-thread, 1/2"x20tpi fits 9019-c and 1517 prefill valve port and 1/2"x20tpi female NPT plugs. 3/8”, 1/2", or 3/4" For those who have paid extra to have a single central connection, no pulse interception, no flush in place, but the additional cost of a “T”. Dampeners that do, flow goes through, but pressure pulsation does not.
