Grundfos SQ Flex Solar Submersible Well Pumps

Grundfos Solar Submersible Well Pumps
Grundfos SQF pumps are more expensive than some other submersible solar pumps, but they also are much more tolerant of water that is not perfectly clean.

All SQ-Flex pumps can operate from 90 to 240 Volts AC, and/or 30 to 300 Volts DC. Not recommended for use with modified sine wave inverters (sine wave are OK).

We have been selling these pumps for over 8 years and have never had a warranty claim or repair.
