The COST $$ of Air Operated Double-Ended Diaphragm (A.O.D.D.) PUMPS
with Various PULSEGUARD Dampers

Saving 40%, AND having stable pressure for free,
when flow smoothing systems with an AODD

by avoiding single connection "Pulse Dampers" because they can not respond.

22 M3/Hr. (100 USGPM) heavy oxides slurry at only 1.5 meters / sec in a DN80mm line settles our and plugs the Damper / Accumulator. The need is for flow-through constant agitation & lower connection cost.
160 in3 pulse volume from diaphragm reversal & 1,000 in3 - 16Lt. Acc., only reduced spike 30%

3 pcs. CPVC Ts3" $102
1x3"Flg + 3" NPT $17
pipe coupling $5
6 Hrs prime, bondfit-up & Hydro $430
4.3 USG PVC Acc $1,136
Total $1,680

2 Ts and a flange were saved by using a accumulator safety block, to which the damper face "O" seals and which provides for bracket mounting.
The straight line from pump to damper guts gave pressure peak clipping. 2" pipe gave 3M/s. velocity
The 720 in3, 4 connection damper does more than the 16 Liter Accumulator; but as the path is not through the damper, stable pressure was not evident.
1 pc. 3" socket T $32
3.75 Hrs. fitting prep. & Hydro $269
11.8 Lt. Damper c/w pipe base $1,248
Total $1,549
A (415 in3) 6.75 Liter (125 psi) 8.5 Bar 4 connection true flow through FLEXORBER LP damper, provides continuous agitation, in place flushability, saves all 3 T pieces and out performs an accumulator more than twice its size - 2.9 Hrs. Fitting prep. & Hydro. $208
6.7 Lt. Flexorber LP $800
Total $1,008

Pressure travels 300 times faster than flow
So pulsation - flies straight past a "T"!
Because flow is so slow, there is time to flow up, come to a stop, and flow back down a "T" on the other hand, whatever the residual pressure pulsation level is, it will fly straight past a "T".

Mass of liquid in a pipe is transferred at not above 180 inches/sec or say 460 cm/sec


Pressure in a fluid travels at, Mach 1 (in Air)
In harder substances (liquid) is transferred at up to 4000 MPH, or say 140,000 cm/sec.

CONCLUSION:- With 300% greater efficiency, because flow fluctuations & pressure pulsation are forced to see the inside of PULSEGUARD PULSE DAMPERS, are more compact vessels and DO MORE WORK FOR A LOWER COST
hence the saying:-

Dampers that do, flow goes through, BUT pressure pulsation is caught

DON'T FORGET! This takes you straight back to the beginning -- don't use back, back, back Explorer button.

Selecting Pulsation Dampeners for Different Pump Systems.
Flow through pulsation dampers are at least 3 times more efficient than T off line accumulators.
Dampeners that do, flow goes through, but pressure pulsation does not.
