Submersible Solar Well Pumps | The Best Selection Online

Submersible Solar Well Pumps

If you are pumping from a well, we have solar pumps that can deliver from 1 gallon per minute to over 75 gpm. The smallest pumps, the low-power diaphragm pumps from SHURflo and SunPumps, operate from two 50- to 100-watt solar modules, depending on the head (vertical distance) they are pumping. They can pump 500 to 1000 gallons per day and lift water 200 feet. These pumps require service every 2 to 4 years.

 If you have a higher lift, need more water or want a pump that does not require service for 10 to 20 years, the Grundfos SQFlex solar well pump is a good choice. The SQFlex solar pump can lift water over 800 feet and can pump over 20,000 gallons per day at lower lifts. The SQFlex pump has great flexibility in the power source and can be powered by solar modules, a wind generator, a fuel powered generator, and inverter or the utility grid or a combination of several of these. 

Larger, custom-designed solar powered pumping systems can be supplied by SunPumps. Contact us if your needs fall outside of the flow or lift specifications found in the following pages.

Grundfos SQFlex Solar Well Pumps

The Grundfos SQFlex family is an environmentally-friendly water supply system. SQFlex pumps are fitted with a permanent magnet motor which enables the efficient use of energy from a wide range of supply options. The pump system offers the perfect water supply solution in remote areas where water is scarce and the power supply is non-existent or unreliable.

Very flexible as to its energy supply and performance, the SQFlex system can be combined and adapted to any need according to the conditions on the installation site. A battery backup system can store the extra energy generated and take over when the primary energy source is not available.

SQFlex is more than just a pump – it's a complete system. Thanks to its built-in electronics, the pump is compatible with both DC and AC power supply without requiring an external inverter.

The complete range consists of eleven different pump sizes: Five helical rotor pumps for applications where a high head is required, and six centrifugal pumps for applications where a greater flow rate is necessary.


Being designed for continuous, as well as intermittent operation, the SQFlex system is especially suitable for water supply applications in remote locations, such as:

  • Villages, schools, hospitals, single-family houses, etc.

  • Farms

        - Watering cattle
        - Irrigation of fields and greenhouses

  • Game parks and game farms

        - Watering applications

  • Conservation areas

        - Surface water pumping
        - Floating pump installations for pumping water from ponds and lakes
