Pumps, Submersible

 
Grundfos SQFlex Submersible Pumps

This pump lifts water up to 800 feet.

The SQFlex family is an environmentally-friendly water supply system. SQFlex pumps are fitted with a permanent magnet motor which enables the efficient use of energy from a wide range of supply options. The pump system offers the perfect water supply solution in remote areas where water is scarce and the power supply is non-existent or unreliable.

Very flexible as to its energy supply and performance, the SQFlex system can be combined and adapted to any need according to the conditions on the installation site. A battery backup system can store the extra energy generated and take over when the primary energy source is not available.

SQFlex is more than just a pump – it's a complete system. Thanks to its built-in electronics, the pump is compatible with both DC and AC power supply without requiring an external inverter.

The complete range consists of eleven different pump sizes: Five helical rotor pumps for applications where a high head is required, and six centrifugal pumps for applications where a greater flow rate is necessary.
 

Applications

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

  • Villages, schools, hospitals, single-family homes, etc.
  • Farms
            - Watering cattle
            - Irrigation of fields and greenhouses
  • Game parks and game farms
             - Watering applications
  • Conservation areas
            - Surface water pumping
            - Floating pump installations for pumping water from ponds and lakes

Features and benefits

  • Renewable energy supply: solar panels or wind turbines
  • Built-in electronics, easy installation
  • Reliable water supply
  • Low operating costs
  • Dry-running protection
  • Built-in motor protection
  • High Efficiency
  • Maximum Power Point Tracking (MPPT)
  • Wide voltage range
  • Built-in sand shield

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 IO101-115 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.

Use the table below to choose a pump.

 
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.

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.
