Gear, Spur, Normal & "Internal"


Gear, Spur, normal & “Internal”. Pipes attached to gear pumps with 7, 11, or more teeth driven @ 300 rpm & above, need high frequency and acoustic protection. Lower frequency and larger volume systems from internal gears, need volumetric damping.

Vane & Positive Displacement Fleximpeller


Vane and positive displacement flex impeller. When pipes are larger than necessary for 2 to 10 ft/sec. Flow velocity (according t cP) there is no amplitude dissipation; audible whine, and long pipes “shake”, may occur. An acoustic decoupler will generally suffice.

Centrifugal Single & Multistage, "Canned" & "MAG-DRIVE"


Centrifugal Single & Multi-Stage, “Canned” & Mag-Drive”. Pressure “pulsation” comes from the reverberation of the start-up surge, its frequency is from the pipe length. The amplification of high frequency from the flutes by the pipe system, is addressed by acoustic de-coupling.

Progressive Cavity & Worm


Progressive cavity and worm. The higher the viscosity the greater the effect of drag and the less well the feed end is filled. This causes pipe pulsation from what is otherwise a smooth flow. Flo-thru dampeners dampen what would go past a “T”

Screw & "Auger" Meshing or Geared


Screw and “auger” meshing or geared. Larger long piping systems 10” through 30” respond by jumping. To prevent weld cracking and pipe fatigue, cushion chambers, through which material flows are used.

Two Lobe & Three Lobe


Two Lobe and Three Lobe. Low amplitude medium frequency, often viscous, flow fluctuations and system response pressure pulsation, is addressed by in-line flow-thru, interception, which also provides in place flushability before service.

The most volumetrically efficient of all pumps, due to the minimal dead volume, (unswept by the plunger) between the check valves. They emit virtually no velocity jump shock. Only flow fluctuation removal is necessary.

Air Operated Double End Diaphragm A.O.D.e.D.


Air operated double end diaphragm A.O.D.e.D. The time delay of direction change, governs dampener size. The essential is a large air hose to drive the pump. With large air supply, the pulse to be filled is only one sixth of the volume displaced per stroke per end.

Hose, Tube & Peristaltic


Hose, Tube and peristaltic. When the shoe or roll mashes the hose a shock goes back up the suction line. When it lifts off the discharge end of the pump hose, a void occurs, liquid rushes back, pressure falls. Dampeners are relative to shoe size.

Diaphragm (Multi Layer) Metering, RPM or Stroke Variable


Diaphragm (multi layer) metering, rpm, or stroke variable. Liquid is compressible. Otherwise the velocity of a pressure wave would be infinite. Because process liquids are often very compressible, and pipework “happens” isn’t designed, velocity jump shock and system pulsation can be massive.Diaphragm (multi layer) metering, rpm, or stroke variable.

Diaphragm Sealed, Metering Packed Plunger


Diaphragm sealed metering packed plunger. The benefits of hermetically sealed displacement, plus the efficiency and no shock of a packed plunger. With cost savings and longer diaphragm life. Small flow-through in place flushable dampeners – that is it.

Power Pumps, Multiplex-"674", Triplex, Quin, Septuplex etc.


Power pumps, multiplex – “674”, triplex, quin, septuplex, etc. Decrease in con-rod length, increase in rpm, weight of check valves, all increase the amplitude of pulsation. Increased number of plungers, decreasing check valve travel to 0.25 x throat diameter less dead volume, all help.Power pumps, multiplex – “674”, triplex, quin, septuplex, etc. Decrease in con-rod length, increase in rpm, weight of check valves, all increase the amplitude of pulsation.

Fluid Driven Intensifiers & Injectors


Fluid driven intensifiers & injectors. Damping in HP injection and intensifier systems is more akin to decompression shock interception than volumetric flow fluctuation removal. The suction stroke is usually fast. Both suction and discharge need the “flo-thru” approach.Fluid driven intensifiers & injectors.

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.
