Model Types

DS, DP, DV, FG & HG Units

Bladder type units specifically designed as Pulsation Dampers which feature maintenance friendly top access for bladder removal and replacement in situ.
Standard material is 316 stainless steel, polypropylene or Alloy 20 although dampers in other materials such as Titanium, Hastelloy, Monel, Duplex Stainless Steel, PVDF and PVC are regularly manufactured. Maximum pressure available is 2500 bar (36,000 psi).
The membrane can be supplied in NBR, EPDM, FPM(B), FPM(GF), CR, ECO, CSM and IIR rubbers.
Screwed or flanged, a choice of single, twin or multiple porting is available.
Many thousands of these dampers worldwide testify to the effectiveness of this simple design concept in smoothing the flow from reciprocating pumps worldwide.

FD Units

Simple construction features a contoured Teflon (PTFE) diaphragm with a 316 stainless steel housing as standard and the choice of screwed or welded flange connection. Housings may also be material such as Polypropylene, PVC or special alloy and twin port configuration is available as an option.

FB Units

These Teflon (PTFE) and alloy metal bellows models offer the highest quality available in process dampers. Teflon bellows are knife cut on precision CNC machinery. Metal bellows are formed and welded in a tightly controlled proprietary manufacturing process. These units are ideal for exceptionally aggressive liquids and very high temperatures. The FB/TD features a double membrane construction with a bellows process membrane (as 'FB') and provides a unique application solution for high pressure aggressive liquids services.

FG/TD Units

Suitable for hygienic (CIP) applications this 'transfer' damper features a unique double membrane design and has been certified to exceed the basic requirements of the EHEDG CIP test procedure. This truly hygienic answer to pulsation problems in the food, beverage & pharmaceutical industries is supplied with a choice of elastomeric membranes and a 316 stainless steel housing with polished finish option. It is also ideal for use with difficult to handle suspended solids.
