Bladder type Dampers with Stainless Steel Bodies


PipeGuard Tabulated first by volume from smallest to larger, then by acending pressure.  Typical volumes and standard pressures for small volume gas in elastomer bag "bladder" type pulsation dampers. 16 ml  through  1000 ml at ex stock ratings.  Nrmal configuration  to  smooth volumetric flow and intercept  pressure wave frequencies cause by the lengthf of pipe nodes. Interception prevents the piping from "talking to the pump, and the pump talking to the system; for maximum performance within one unit.

 Ease of top end re-service FOR BLADDER REPLACEMENT  IS PROVIDED  IN THIS  DAMPER DESIGN
  Beware of apparent copies, your assurance is  use of these from the 1965  design originators.
                                                         TYPICAL DAMPER EASE OF DISASSEMBLY
        Up to 400 bar / 6000 psi  daampers , for top end re-service  are normally "segmental  lock ring" construction.
       This feature introduced in 1965 , now known as ASME VIII UG 34 m , when we depoy with a step on  our "end closure"  (aka flat "head" plate) makes dampers tamperproof  until all pre-fill nitrogen pressure has been vented.
        Additionally with the proportional detail dimensions used by PulseGuard,  a controled  leak down de-pressureization produces a safety feature a t 4.40 times rated max working pressure.
 Please see below.
PipeGuard Typical  pressures for medium volumes of  gas in elastomer bag "bladder" type pulsation dampers.  More than one  liter  and less than  four  liters  at voarious standard ex-stock stainless steels , normally 316 L grade  equipment.  The damper volumes and pressures listed in this tabulation are only the most popular  size combinations. There are may other  pressure  ratings available though no necessarily off the shelf.   Should you not find exactly what you need from  this  listing of 27  sizes and pressures of dampers, please call  Di. at  --44 (0) 161 480 9625  (ourm number since 1963)  -  49 years in the damping business !

300% better performance
PipeGuard Typical volumes and pressures for larger gas in elastomer bag "bladder" type stainless pulsation dampers. four liters through fifty liters.   The production of large gas bag "bladders" in one piece without glue, bonds, or seam splices by high intensity transfer moulding , enable the choice of the least reactive, most widely compatible ,  elastomer compound ingredients . This is because the "blsdders" do not have to be stuck together in the production process. Where you experience compatibility ptoblems with "O" ring materials it does not follow that our compounds of a given name like for example "Buna N"  or "EPDM" will  suffer from incompatability.
