Understanding How it Works
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. /
