comparing PSI to pump "lift"?
 

I'm curious if there's any way to correlate PSI to pump "lift" and GPH that is indicated on the packaging of most submersible pumps?

Not that I know of.

On google I've located one or two formulas 1 PSI = 2.034 feet of lift (or aproximately) but it seems dependent upon the volume of water your moving and diameter of the tube. So I'm going to try my experiment anyway since I bought an extra water pump...

more news later! ;)

1 psi = 2.3 ft of friction-free lift. If 'lift' is through a pipe, you will get less lift per psi. Other sources of friction loss, misting heads, etc., have the same effect.

I don't know what I did with it, but mine came with one....so they do exist. Maybe you can try the company's website (that makes your pump).
