Selecting Pulsation Dampers for Different Pump Systems
Flow through pulsation dampers are at least 3 times more efficient than T off line accumulators. Dampers that do, flow goes through, but pressure pulsation does not.

Have PulseGuard select or suggest a pulsation damper that meets your particular system requirements!

Pulsation dampers are your solution to longer lasting pumps and pipe systems. Vane pumps, need to be isolated from high frequency system response by the use of no moving parts WAVEGUARD dampers. For systems where the compatibility of FLEXLON PTFE is required, please see the flexorber range. Where the rpm is low, and an elastomer is known to be compatible, please consider the PIPEHUGGER LP damper range. Air Operated Double ended Diaphragm pump, AODD pumps can transfer liquid as smoothly as a turbine with the right damper. Where plastic is essential use the PIPEGUARD Plastic range. pulsation dampers solve your pulsation probelems. Where Stainless steel and an elastomer can be used, choose from the PIPEGUARD LP models. For PTFE FLEXFLON compatibility please see the FLEXORBER LP inventory. Gear and lobe pumps work without a whine when connected through an in line muffler. At high frequency use the no moving parts WAVEGUARD.
Low frequency either the PIPEHUGGERs with synthetic rubber bladder, or for Flexflon, PTFE, or EIDP Teflon the FLEXORBER ranges dampers are ideal. Hose pumps or tube pumps, sometimes called peristaltics, are low frequency devices, they lose their suction side positive spike from shoe or wheel impingement, when used with FLEXTUBE ClearFlow attenuators - See the PUMPGUARD range. For off line single connection Dampers, see PIPEGUARD which can be used to prevent discharge backflow from shoe lift off. Hermetically sealed multiplex sandwich diaphragm pumps are matched with double layer secondary containment sealing tell-tale alert dampers. Whether for use with the single chamber sealed metering pump, top right, or the multiplex version at the bottom right, if a sealed hazard class pump is required, then a matching FLEXORBER hazard class damper should be chosen. Sealed pump safety, matched by pressure vessel damper safety of the FLEXORBER, for the system is the only safe choice.
Where secondary containment and multilayer FLEXFLON PTFE are not necessary, then for flow fluctuation removal and an elastomer membrane a link to the PIPEGUARD price and dimensions list is provided. Where the need is pressure pulsation reduction and flow fluctuation smoothness then the elastomer bladder flow through HIPEHUGGER is your choice. Injection systems have the decompression shock removed by flow through interceptors, link to the duplex (2205, F-51, UNS S31803) and super duplex (2507, UNS S32750) all stainless PIPEGUARD high pressure and super pressure range price and dimension page. Quintuplex and septuplex pumps, bottom left, use a no foam, no gas bag, no moving parts, spherical flow through damper. The flow fluctuation volume is small, the frequency is high. Pressure wave interception is what you need more than volume compensation. Dosing pumps use in place flushable dampfners. A print out of the site map will show you all your options and which one to take. Liquid in the bladder, cushion gas in the shell. Large diameter ratio to connection diameter kills the pressure waves. Low pressure and flow through types too, stop suction side negative pressure waves from breaking the supply column into slugs. No moving parts pressure pulse interceptors, cause the pressure transients to have to take multiple flow paths. A pulsation damper will help with your pulsation dampening, cause pulsation dampers, or pulsation dampers, deter pump pulsation, flow fluctuation, pressure pulsation, flow smoothing. Pulsation damping with a pulsation damper have a pulse damping or pulse dampening way of using any of the following: a pulse damper, pulse damper, pulse dampers, cavitation damper, cavitation dampers, cavitation damper, cavitation dampers, flow fluctuation reduction, flow fluctuation reducers, acoustic attenuators, pulsation attenuators, pulse attenuation, pulse attenuators, reduce acceleration head loss, acceleration head loss preventors, acceleration head loss reduction, cavitation damper. The transients have their base time stretched and the pressure amplitude falls . Prevent amplification and resonance. Dampers with Flexflon modified PTFE diaphragms have 4 times the permeability life of prior designs and cost half the price. Gas in the bag type flow fluctuation reducers act as an accumulator of the peak flow and deliver their stored volume back to the system when the flow velocity otherwise falls. All stainless 316 or duplex stainless & superduplex models available to 30,000psi. Clearflow flextube type for slurries Centrifugal pumps need protection against pipe system startup surge generation. Use your PulseGuard, pulsation damper.
