WHICH PUMP START-UP SURGE 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 PUMPED 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 compatiblity requires PTFE, Flexflon, or DuPont virgin teflon. LiquiBello For extreme temperature	Click on the picture or names for product pages
	The faster the pump starts, the higher the surge.

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.
