I'm looking at a SQ (10s model) (120v)
Delivers 5 gpm at maximum lift of 200′, up to 10 gpm at lift of 160′ or less. Maximum power used is 1200 watts.
Total lift of any pump is height between water surface down the well to the elevation where water is delivered to a non-pressurized tank. Reduce maximum lift by 92 feet
if used to pressurize a bladder tank to 40 PSI.
My 230v, 1/2 hp pump gives me 50PSI
I can live with 40psi knowing I'll have water if the grid goes down
