This pump for water lifts of up to 525 feet.
They 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, and with the name Grundfos on it, you know it is built to last and is maintenance-free. Some SQFlex pumps will fit into a 3" well.
Seven pump models can deliver from 4 GPM at 525 feet to 50 GPM at 20 feet of head with 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 application. The SQFlex has built-in protection from dry-running, overload and overheating.
The SQFlex pump can run on a solar arrays starting at 129 watts. The array must have an operating voltage over 30 volts. The array can be made any combination of 3 or more 12 volt nominal modules in series or 2 or more 24 volt nominal module.
Grundfos also has a specially designed Whisper 100, 1KW wind generator with 150 VDC output for applications using wind power. Please contact us for information.
Poly pipe in rolls is acceptable instead of rigid pvc or galvanized, because the slow start feature of the motor reduces startup torque and twisting of the pipe.
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. Use the table below to choose a pump. Left Column shows total head in feet and meters. The top row shows array wattage/number and suggested type of modules. Boxes show seasonal pump performance and maximum flow as shown in the sample box to the right>>>. |
|
Select the row with the head (total lift) that most closely matches your application.
Move across the row to the column that contains the desired daily volume or peak flow rate. Note the pump model in that block and wattage of the PV array in that column.
**Note: Daily volume and flow calculations are based on 38° North latitude location, fixed array tilt of 38° and 4.5 kWH/m2 (POA) winter, and 7.5 kWH/m2 (POA) summer solar insolation.
The pump model is optimized for summer operation.
Up to 40% more water can be pumped in the summer if the array is on a tracking mount. The output can vary with different locations and years, and is not guaranteed.

AC SUBMERSIBLE PUMPS |
This pump can be used for water lifts of up to 600 feet.
The SQ series pump features a permanent magnet motor controlled by an electronic frequency converter developed by Grundfos. It starts slowly, without surge, so it can be run on a much smaller inverter or generator than any conventional AC submersible pump. It is a high efficiency pump and motor with built-in dry-run protection.
This is the ideal pump to use if you are pumping from a well and into a pressure tank, especially for solar-powered homes. They work on modified sinewave or sinewave inverters. Highest volume pumps run on 240VAC. They can be powered by inverter systems with 240 VAC output, or by using an autotransformer to step 115VAC from an inverter to 240 to run the pump. Minimum well diameter of 3" is required. Use 2-conductor with ground pump cable.
Warranty is 18 months from date of installation or 24 months from date of purchase, whichever comes first.

Shurflo 9300 Submersible Pump
This pump can be used for water lifts of up to 230 feet. Use this lightweight submersible pump for livestock, irrigation or remote home application with low water requirements. The 9300 is a positive displacement diaphragm type pump with very high efficiency, but a much shorter life than centrifugal or helical rotor pumps. Diaphragm should be replaced every two to four years, depending on pumping volume. The Shurflo 9300 can be operated on a 12 or 24-volts battery or, with the use of one of the Shurflo Pump Controls, directly on a PV array. The pump can lift 1.3 GPM to 230 ft. and can pump nearly 2 GPM from very shallow wells. It measures only 3.75" diameter x 12" long. The 902-200 controller comes in an outdoor enclosure with water level sensors and sensor wire. It can be operated from a 12V or 24V array. The 902-100 control must be mounted in a dry location and used with a 24V array Performance on a 12-volt battery will be less than 1/2 the flow on the chart at right. 1 year warranty.

This pump can be used for water lifts of up to 231 feet.
SunPumps SDS series submersible pumps are efficient, low voltage, DC
powered, diaphragm type positive displacement pumps designed specifically
for water delivery in remote locations.
They operate at 12 to 30 volts DC which may be supplied from a
variety of independent DC power sources. There are two models of SDS pump.
The D-series has a dual diaphragm and fits in a 4-inch well.
The Q-series is a higher flow pump that fits in 5-inch or larger
wells. A PCA-30-M1 controller must be used with all SDS pumps.They can be
used to fill an open tank or in pressurized water delivery systems.
Simplicity is the key feature of the SDS series pumps. They are easy to
install, require very little maintenance and are repairable.
Use the table to choose the pump that best meets your flow need at a
given head. At 15 volts, flow is slightly less than half of the 30-volt
flow.

This pump can be used for water lifts of up to 32 feet.
LVM pumps are constructed of polyacetal plastic, enabling them to pump almost any liquids.
They are small enough to enter the opening in a five gallon container or a 2" well casing. The outlet is a ½" hose barb. The intake has a removable strainer with another hose barb for inline use.
These pumps can be used for most general intermittent pumping applications, like hosing down cars, vans, boats, pumping into and from containers, emptying bilges, etc. LVM 105 comes with battery clips.
These pumps are designed for 12 volt operation and will be damaged by array direct operation if voltage goes above 15 volts.
Made in England.
