Description

The Grundfos SQFlex solar pumps can be directly powered by solar or wind power or can be run on an inverter, a generator, a battery or the utility grid, or any combination of these sources. Virtually any source of power, 30-300 VDC and 90-240 VAC, can be used to run the pump. They can operate on a series string of PV modules with a total peak power voltage over 30 volts, but the pumps efficiency will be much higher at voltages over 100 VDC. SQFlex 3 and 6 pumps will fit into a 3" well.

Seven pump models can deliver from 2 gpm at 600 feet to 65 gpm at 20 feet of head with a 1 kilowatt solar array or less. Helical rotor pumps (models 3, 6 and 11) for high head applications and centrifugal pumps for low head applications assure a pump that is efficient for any use. The SQFlex has built-in protection from dry-running, overload and overheating.

SQFlex submersible pumps have a 2 year warranty from the date of purchase. A 5 year extended warranty is available separately.

The Whisper 200-150 V wind generator can be connected directly to an SQFlex pump. Please contact us for information.

Optional Controls

The CU200 interface box communicates with the pump and monitors operating conditions. Built-in diagnostics indicate faults and dry-running, display operating status, power consumption and water level switch input. The water level switch interfaces with the CU200 control to turn off the pump when a tank is full.

The IO100 is a simple control box with cable terminations and a manual on/off switch. It is a great interface between a solar array and the pump to allow you to turn off the high voltage array when working on the pump.

The IO101 is an interface for using AC backup on a solar pump. An automatic transfer switch disconnects the solar array when AC power from a generator, utility connection or inverter is present. When AC power stops, it automatically reconnects the array to let the sun continue pumping.

The IO102 interface unit is used for systems powered exclusively by a wind turbine or by a combination of wind and PV.

You can use several controls if you need more features than one control can provide.

The SQFlex pumps will not function with a GFCI in the supply circuit, and should not be used where a GFCI is required.

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.

Damn good pump

6SQF2 & CU202 Well... didn't get of to a good start. Spec indicated 1" outlet. Nope, mine was 1 1/4". Luckily had adapter on hand. Rigged the pump temporarily on 1/2" 160psi poly pipe just to fill gravity tank for house water. Wired it direct to 2 mismatched solar panels ( 235w & 310w) series voltage of 74vdc and got 5GPM. Not bad! At the time just manually turned pump off when tank was full. Week later my 3/4" 160psi poly pipe showed up. Reset the pump permanently @ 110' down and wired in the CU202 to the solar and a (not my favorite) N/O pressure switch. Couple days later got a dry run alarm on the Bluetoothed 202. Glad the pump has a water sensor. Found out with the CU202 you can limit the max pump RPM, so set max to 2000 RPM. WOW! I'm impressed! Also found out you can change between different types of pressure switches. Great! And as long as you stay within the voltage limts it doesn't mater weather input is AC or DC. Although spendy i think the CU202 with the pump was a marriage made in heaven. I've been through a couple sunpumps and a vevor. I like it!
