PRESSURE PULSATION DAMPING

On typical diaphragm head chemical & process metering pump piping systems

Simply, how it works:

1.
Pressure measured at one place in a piping system can be seen approx. 1400 meters away, (o.87 miles away) one second later. That is to say the speed of pressure wave transfer is generally over 3,000 miles per hour.

2. As pressure goes so fast, a piece of pipe, say 15 meters long (approx. 50 ft), reflects it back to source in 0.02 seconds, or say at 50Hz. Another thought is that it will pass a 100 mm "T" branch in 0.00007 of a second! So a one connection dampener on the T can not respond.

3. Frequencies from short lengths of system, must be addressed by flow through dampeners .*

*Flow through, dampeners give:
More Flow Fluctuation Smoothing as well, PLUS
A. Pressure pulse interception
B. Flushability in place
C. Standardization (Flow-through are standard inventory) All at a lower cost!


IF FOR SOME REASON YOU REALLY MUST NOT HAVE THESE BENEFITS, KEEP THE LOWER COST, BY USING ONE CONNECTION, AND SAVE A "T" BY USING THE OTHE RFOR R.V., DRAIN, or GAUGE.

Flexorber LP cross sectional descriptive color cut sheetPrinciples of pressure activity reduction - briefly:
1. Pressure transients, going from a small hole into a large diameter space, die away exponentially with distance to the first surface they would reflect from. II. Additionally, mass of liquid deadens the pulse. III. When the cavity is also 8 times larger than the exit hole, what is left has difficulty fining its way back to the system.


Importance of Prefill:
For a pressure pulse interception duty, to 50 % of system pressure, to keep diaphragm up & dampener half full of liquid.


Installation options:
For Best Results, small connection to system for constant flow, larger to the pump for peak flows. Not more than 10 pipe IDs long.
Piping option cross sectional views at "90/90" and "45/45"

"Dampeners that do - Flow goes through,
But Pressure Pulsation does not."
