Pulsation Dampener part number that matches Packed Plunger Pump

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

1. dampeners listed below are from 1000s of "off the shelf" inventory dampeners , for preventing pipe systems from converting plunger flow fluctuation into pressure pulsation. Call toll free 1-888-DAMPERS (326-7277) 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. The right pipe bore improves pressure pulse damping and saves more pipe than dampener costs. Where an area of 2 suits constant suction velocity, 6 suits peak velocity suction stabilizer(s) to pump inlet. 3 suits pump outlet to discharge bottle and 1 suits constant discharge out of bottle.

With ELASTOMER BLADDER. No flow reversal pressure generation in a single connection. Perfect discharge acceleration head prevention, and pressure pulsation interception. Capacitance + Direction change impedance. Ultra efficient high transient & frequency performance with quick release piping base block. Save a “T” & have 3 times as much performance

No flow reversal pressure loss in a single connection. Perfect suction acceleration head loss recovery. The only suction dampener that can be fitted exactly where it belongs; close coupled directly at the suction check valve of the pump it protects.
No flow reversal pressure loss in a single connection. Perfect suction acceleration head loss recovery. The only suction dampener (suction stabilizers) that can be fitted exactly where it belongs; close coupled directly at the suction check valve of the pump it protects.
With “FlexFlon” or PTFE diaphragm. No flow reversal pressure generation in a single connection. Perfect discharge acceleration head prevention and pressure pulsation interception. Capacitance + Direction change impedance. The only “FlexFlon”/PTFE high pressure dampener that intercepts & isolates a pump from system pressure wave response. Transients are forced into the damping chamber by the piping base block design, from which dampener is a 4 bolt quick release. Maintain pipe integrity, weld base block into the pipe permanently.

The original "Elastomer gas bag" dampener from its originators. For externally corrosive environments, economical high pressure capability by tall and slim, but sacrifices high frequency capability of the larger diameter true dampeners - the PipeHugger and the FlexOrber above. Although PipeGuard has a stiff long thin bag, performance is enhanced 3x by forcing response with a flow thru. Capacitance + Direction change impedance.

When you see a pulsation dampener or a pump of particular interest, please request literature dedicated to that subject.


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.
3. 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. 2 connection dampeners are standard lowest cost. WaveGuard and dampeners for 10Hz. & above, IE systems 300 meters (1000 ft.) or less, must use FLOW-THROUGH.

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.
