 BLADDER (ELASTOMER) DAMPERS
Models DS, DP, DV, FG & HG
Flowguard’s bladder-type vessels are ideally suited for application as pulsation dampeners. They feature maintenance friendly top access for bladder removal and replacement on site.
Standard (shell) materials are 316 / 316L stainless steel, polypropylene or Alloy 20. Vessel bodies in other materials such as  Titanium, Hastelloy, Monel, Duplex stainless steel, PVDF and PVC are also available.
Standard bladder materials are supplied in nitrile rubber, EPDM, Viton (B), Viton (GF), neoprene rubber, Epichlorhydrin, Hypalon and butyl rubber.
Designs are available in pressure ratings to as high as 1,380 BarG (20,000 PSIG).
Screwed or flanged connections and a choice of single, twin or multiple porting is available. Many thousands of these dampers installed worldwide testify to the effectiveness of this simple design concept in smoothing the flow from reciprocating pumps.
