This is the ultimate pump for water lifts for up to 650 feet. Virtually any source of power, 30-300 Volts DC and 90 -240 Volts AC, can be used to run the pump. They can operate on a series string of PV modules with a total peak power voltage of at least 30 volts, but their efficiency will be much higher at voltages over 100 Volts DC. The motor is designed to draw a maximum of 8.4 amps, which means that many types of PV modules can be used efficiently, including 60 cell modules with outputs of up to 260 nameplate watts.

Application areas

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

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

· Farms and ranches
– watering of livestock
– irrigation of crops and greenhouses

· Game parks and game farms
– watering applications

· Conservation areas
– surface water pumping

· Ponds and lakes
– floating pump installations

Getting it right from the start

Sizing and selection of the optimum SQFlex system has never been easier. Based on a few location-specific variables such as average sunshine and wind speed and your estimated water needs, we can determine proper system sizing for you.

All you need to determine is the following three parameters:
· geographical location
· required maximum head
· required water quantity per day

Contact us for a customized sizing proposal.

3SQF through 11SQF pumps will fit into a 3" well.

16SQF through 60SQF pumps will fit into a 4" well.

Eleven pump models can deliver from 82 gpm at 6 feet of head to 4 gpm at 800 feet with a 1.6 kilowatt solar array or less. Helical rotor pumps (models 3, 6, and 11) for high head applications and centrifugal pumps (models 16, 25, 40, and 60) for low head applications assure a pump that is efficient for any use. The SQFlex has built-in protection for dry-running, overloading, and overheating.

This pump:
Max Head: 395 feet
Max Flow: 13 gal.min.

SQFlex pumps have a 2-year warranty from the date of purchase.
