How deep can a solar pump work?
RPS carries solar pumps that can handle up to 1,000 feet of total pump head. Total pump head is different that how far beneath the surface of the water a solar pump can be submerged, about 400 feet. If your well has a shallow static water level (how far down to the top of the water) but a deeper overall depth, you may have to consider placing the pump a bit further up in the well.
Pump sizing will be determined by the amount of water you are looking to generate and your Total Pump Head. Your Total Pump Head is the Static Water Level (how far down to the top of the water) if pumping directly into a tank level with the well. If there is a rise in elevation from the well to the tank, just add that on. If pumping from a water source other than a well, we just need the total lift, distance and pipe size. If pumping directly into a pressure tank, add 2.31ft per psi of pressure. Most tanks are 40 psi so we roughly add 100ft onto the static to calculate the total head.
Pro Volume and Deep Systems
For wells up to 300 feet deep, take a look at our line of 3″ submersible pumps.
For deeper or more volume intensive applications, you can choose between a ProV, higher volume lower head, or ProD, lower volume high head up to 1,000 feet. Our Pro3000D (3 HP) is popular for extremely deep wells, check out the pump curve below.
