Pulsation Dampener part number that matches Gear Pump

gear pump

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.

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

For externally NON-corrosive environments, with elastomer bladder. Large diameter liquid bladder response characteristics suit low amplitude fluctuations removal.

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.

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.

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.
