WHICH TYPE OF PIPELINE SHOCK ALLEVIATOR TO USE

The amplitude of the surge is from the mass and time in which to be accelerated.
It is critically important to make an accurate estimate of pump spin-up time.
Frequency is from pipe length.

FOR WHICH TYPE OF LIQUID SERVICE

JumboFlex
For liquids that will not require a corrosion resistant vessel shell.

SurgeGuard
For liquids where, being in the bladder, saves having a corrosion resistant shell.

FloatoLator
Used where a suitable bladder Flexorber size or liquid compatible material is not available.

Flexorber
When your liquid compatibility requires PTFE, Flexflon, or DuPont virgin teflon.

LiquiBello
For extreme temperature

The faster the valve closes, the higher the pressure spike. It is very important to put an accurate figure on valve closure time.

Visit LIQUID DYNAMICS Intl. Ltd. LDi offers analytical and modeling services. They predict these and similar problems, before pipe systems are built. ShockGuard is a licensed run time user of the LDi Ltd. software, ShockView. ShockView enables us to quickly and accurately run your proposed piping system, in our computers and you what the maximum level of pump start up surge, or shutdown shock will be.

Understanding Pipeline Surge / Shock Alleviators
Shock alleviators and shock accumulators do not alleviate shock, nor do surge alleviators and surge accumulators alleviate surge. SurgeGuard, JumboFlex, and Floatolator all work in the same way. They provide a soft place, so that the pump does not have to instantly accelerate all the liquid in the pipe system when it starts. Similarly, they provide a place into which flow can continue, for a time, against increasing resistance, when a a valve has been slammed. In both cases, because time has been increased, peak pressure generation is decreased. In short, they all prevent the peak pressure from being generated.
