Submersible pump fits 4" diameter wells, or larger. Solar submersible pump from Grundfos has only one moving part - no failure likely diaphragms or motor brushes. Surface pump controller is above ground for easy access. Advanced pumping controller is weather sealed for demanding sites.
Grundfos SQFLex is an industry-leading submersible pump for water lifts of up to 800'. Voltage matched ontroller, SQFlex pumps can be directly powered by solar pv or wind generators. Power SQFlex Grundfos pumps with an inverter, a generator, a battery, the utility grid - or combination.
Solar submersible pump runs from 30 to 300 VDC. And 90 to 240 VAC, can be used to power this submersible pump.
Grundfos submersible pumps can operate on a series string of PV modules with a total minimum voltage of at least 30 VDC. Best results at voltages over 100 VDC (10% less efficient at 60 VDC, and 20% less efficient at 35 VDC).
Submersible pump motors draws a maximum of 8.4 A. SQFlex models 3SQF through 11SQF will fit into a 3" well. Grundfos models 16SQF-10 through 60SQF3 will fit into a 4" well.
Grundfos spans eleven different pump models available can deliver from 82 gpm at 6' of head to 4 gpm at 800 feet. Solar PV panels rated at 1.6 kW or smaller solar array.
Grundfos uses ahelical rotor pumps (models 3, 6 and 11) for high head applications and centrifugal pumps (models 16, 25, 40, and 60) for low head applications for best efficiency. The SQFlex has built-in protection from dry-running, overloading, and overheating.
SQFlex pumps have a 2-year warranty from the date of purchase.
