Grundfos SQ-Flex solar pumps will pump water up to 600 foot total head, and can pump up to 85 gallons per minute for shallow wells, depending on model. The helical rotor pumps are what we recommend if you have any dirt, sand, sediment, or high mineral water from your well. The 3 SQF, 6 SQF, and the 11SQF are helical rotor type pumps. All others are centrifugal. All SQF pumps are 17 to 23 pounds in actual weight.
