Pulsation Dampener part number that matches Gear Pump

Pulsation Dampener Size Selection Tables for piping systems where the flow is from a gear pump.

When you see a pulsation dampener or a pump of particular interest, please request literature dedicated to that subject. 1. Dampeners listed below are from 1000s of "off the shelf" inventory dampeners, for preventing piping systems from converting gear tooth flow ripple into pressure pulsation. Call toll free 1-888-DAMPERS (326-7377) for discounts, etc. Choose a dampener matching your pump connection size, for standard damping. Or allow us to calculate for you, from your smoothness required and your system data.
2. Where no OSHA requirement for in place flush before service, nor process need for 1st in 1st out, constant temperature, change of liquid pumped, interception of pressure pulsation; use second connection to save a "T" for RV. PI, or system drain. Two connection dampeners are standard lowest cost. WaveGuard and dampeners for 10 Hz. & above, i.e. systems 300 meters (1,000ft.) or less, must use FLOW-THROUGH.

PipeGuard pulsation dampeners For use in externally corrosive environments. Small diameter gas bag response characteristics are less suitable to low amplitude fluctuations.
For use in externally corrosive environments.
Small diameter bladder (gas bag) response characteristics are less suitable to low amplitude fluctuations.

PipeHugger pulsation dampeners For externally NON-corrosive environments, with elastomer bladder. Large diameter liquid bladder response characteristics suit low amplitude fluctuations removal.
For externally NON-corrosive environments, with elastomer bladder. Large diameter liquid bladder response characteristics suit low amplitude fluctuations removal.
Pulsation Dampeners - PTFE Diaphragm FlexOrber For use with liquids that require PTFE / "Flexflon".
The Teflon® diaphragm stiff response characteristics will leave at least 0.1Bar / 1.5psi fluctuations in the system.
"SoG" part Numbers denote lower pressure items from hydro-forged shells
"FLo" part Numbers denote Medium to High pressure items form solid billet.
WaveGuard pulsation dampeners For high RPM, large number of gear teeth. No moving parts. Flow fluctuation ripple is removed only by the compressibility of the liquid volume. Pressure pulsation response from the pipe system is removed by orifice ration to vessel diameter. For high RPM, large number of gear teeth. No moving parts. Flow fluctuation ripple is removed only by the compressibility of the liquid volume. Pressure pulsation response from the pipe system is removed by orifice ration to vessel diameter.

3. *The question mark “?” = letters, showing your choice of compatible gasket material, add the letter to ordering part number – N= Buna N, E= EP, (H= Hypalon, V= FluoroCarbon, additional cost) A20= Alloy20, H22= Hastrelloy22, Ti2= Titanium 2, Tan= Tantalum, Zir= Zirconium, DSS= duplex stainless steel, SDSS= super duplex stainless steel.



PulseGuard Pulsation Dampeners
Dampeners that do, flow goes through but pressure pulsation does not.

PulseGuard pulsation dampeners are designed to address pressure pulsation, which is caused by the resistance of the system to flow. Therefore our dampeners focus on the system related responsibility and are less related to pump liability.
