COMPARATIVE COSTS DAMPENERS INSTALLED

HIGH PRESSURE BLADDERS INTERCEPT SHOCKING SPIKES, free - Genuine high efficiency packed plunger pumps, do not make the same velocity jump shocks of a diaphragm head, but because they are so good, are often used with compressible system liquids, which cause lost motion, the worst source of pressure pulsation transients.


HARDLY WORKED A ALL, DESPITE MONSTER SIZE, PRESSURE PULSES ARE DIRECTIONAL, AND FLOW REVERSAL IS ONE CAUSE.
But when oversize by a factor of 3, this off line appendage dampener installed in its volume storage accumulator mode, produced "smooth flow". Acceleration head pressures from flow fluctuation were mostly prevented. Pressure pulse system excitation from cylinder decompression nor high frequencies from valve action, and none of the piping system response frequencies were addressed at all. However gauge response hardly reacted, & all really damaging transients could be hidden by reducing the frequency of data capture. (as usual!)

BETTER FOR ONE REASON AND LESS EXPENSIVE FOR ANOTHER.
Although a third of the size of the one above, this performs equally, simply because the mass goes a short distance in a straight line into dampener . Savings not only come from the smaller size, but also by using the second connection for drain, RV, or Gauge, instead of buying and installing an extra "T" piece in the pipe system. Better still, the lower amplitude of the transient spikes will be dampened to some extent, because they are aimed directly at the dampener membrane. High frequencies back from pipe system were not addressed.

THE FULL SOLUTION WAS ALSO LEAST EXPENSIVE
Not to buy a "T" (to put the dampener out of circuit). Used the flow through feature, like a silencer / muffler, or filter, and eliminated acceleration head, and flow reversal in single connection losses, plus high transient spikes and high frequency pressure pulsation were all cured - AND ALL for one fifth - yes 20% only of the one using the single connection approach.
Capacitance + Direction change Impedance does it.

EVEN FOR LP DOSING THRU-FLOW PROVES LEAST EXPENSIVE




The safety of all metallic enclosure plus compatibility of plastic connection block with a PipeHugger LP part Nbr. PeG/Lnd/90i/D115/225p was selected. The PipeHugger LP Lined, is economical when special metal liquid contact parts Ex: Tantalum, Zirconium Hast. C276 are needed.
3. dampener $599
2 "T" pieces

connections
say $156
Total $755
With the idea that plastic is cheap, a twin connection PipeGuard PLAS part Nbr. PiG-plas/60i/B63x214/150p/PVC was selected. Extra cost of single connection special was saved plus one "T" saved by using the second connection of the system relief or drain.
2. dampener $378
1 "T" piece
cut and fit
3 connections
say $67
Total $445
PeG/ss/Tri/20i/1450p/316 Normally mounted at 45 Degrees.
No "T" pieces required, smaller more compact, half the price, 3 times smoother performance. Size items the value of a single connection accumulator. And it doesn't suffer from low temperature fracture.
1. dampener $199
Fit up say $23
Total $222
