SQ Flex High-Efficiency Well Pump. The best well pump available at any price. Comes with "Belmont Solar" system design information. Will be glad to help you with any off-grid solar design & component needs. ____________________________________ The SQFlex system is a reliable water supply system based on renewable energy sources, such as solar and wind energy.The SQFlex system is equipped with the SQF submersible pump. Very flexible as to its energy supply and performance, the SQFlex system can be combined and adapted to any need according to the conditions at the installation site. : 40 - 400 Nominal GPM: 6 Length In.
: 49 Output Size: 1 NPT Pump Type: Helical Rotor Potential SQ Flex applications include: Livestock watering Remote Homes National/State Parks Irrigation Remote Camps In locations where power is scarce and water is a necessity. In the middle of nowhere, the only things you can depend upon are air and daylight.
The SQFlex pump is fully operational from only one or, for greater peace-of-mind, a combination of these energy sources. SQFlex Solar and Wind systems are reliable, low-maintenance and cost-effective.
In addition, the systems are sustainable and totally environmentally sound. Features of the Grundfos 6 SQF-2 SQFlex Solar Pump: Dry-Running Protection: This unique feature shuts down the pump if it detects water shortage. Every SQFlex pump comes standard with this sensor pre-installed, protecting the well from being over-pumped and the pump from damage.Helical Rotor Pump (3): Designed to pump high levels very efficiently, these models allow pumping levels as deep as 820 ft. Diameter allows the pump to go in installations where others can't. Materials: All Stainless steel for long pump life. Motor Protection: Built in protections against over-temperature, overload, and over and under-voltage for reliability, as well as two-way communication with a control box to alert you in case there's a problem. Any Voltage: The motor can operate under any voltage from 30 - 300 VDC and 90 - 240 VAC without additional controls, making sizing and installation easy, even as a retrofit to existing installations.
AC power capabilities mean every SQFlex pump has the ability to use an AC generator for backup power. Simple installation Reliable water supply Virtually no maintenance Cost-efficient pumping every day! Technical Data SQF Pump Power supply to pump 30-300 VDC, PE. 1 x 90-240 V 10%/+6%, 50/60 Hz, PE. Run-up time Depends on the energy source.
Start/stop No limitation to the number of starts/stops per hour. Motor protection Built into the pump. Protection against dry running by means of a water level electrode overvoltage and undervoltage overload overtemperature. Conductivity 70 s/cm (micro siemens). Sound pressure level The sound pressure level of the pump is lower than the limiting values stated in the EC Machinery Directive.Radio noise The SQF complies with the EMC Directive 89/336/EEC. Approved according to the standards EN 61000-6-2 and EN 61000-6-3. Reset function The SQF can be reset via the CU 200 or by disconnecting the power supply for 1 minute.
Power factor PF = 1. Operation via generator Voltage: 230 VAC 10%/+6%.The generator output must be minimum 1000 W (helical rotor pumps) Earth-leakage circuit breaker If the pump is connected to an electric installation where an earth-leakage circuit breaker (ELCB) is used as an additional protection, this circuit breaker must trip out when earth fault currents with DC content (pulsating DC) occur. Borehole diameter: Minimum: 3 in.
Installation depth Minimum: The pump must be completely submerged in the pumped liquid. Maximum: 500 ft below the static water table (220 psi). Suction strainer Holes of the suction strainer: 3 SQF, 6 SQF, 11 SQF: Ã¸0.090 in. Pumped liquids pH 5 to 9.Sand content up to 50 ppm. Note: Specifications and pricing of the Grundfos 11 SQF-2 SQFlex Solar Pump subject to change without notice. Illustrations and descriptions of the Grundfos 11 SQF-2 SQFlex Solar Pump do not claim to be complete. Measures 49" x 2.9".
Long & slender, with considerable weight. Fits within a 3 well! Pump Type: Helical Rotor Installation Tip: For DC or AC voltage between 30 to 230V. Note: If using on single phase AC power.
Use only one leg (120V). Can be used on high-efficiency 120V battery-based inverter. Question: What is the SQFlexs operating voltage range?
Answer: 30-300 VDC (at least 36 V nominal array, 300 max Voc); 90-240 VAC. Question: Can the control boxes run off 240 VAC? Answer: The IO 100 and CU 200 can. There are two models of the IO 101 generator. Box: one for 120 VAC, one for 240 VAC.Conergy currently carries the 120 VACmodel. Question: What is the SQFlexs optimal operating voltage? Answer: 120 V or greater, DC or AC. Question: What is the SQFlexs max current draw? Question: What is the SQFlexs pumping mechanism?
Answer: The 3 SQF, 6 SQF and 11 SQF are helical rotor; the 16 SQF and above are. Question: What is the SQFlexs max power consumption? Answer: 900 W for helical rotor models, 1.4 kW for centrifugal.
If an array is capable of. Producing more than that, the MPPT (maximum power point tracking) SQFlex will.
Consume its max power and no more, and will not overload. Question: What is the SQFlexs max speed? Answer: 3000 RPM for helical rotormodels, 3600 for centrifugal. Question: Do the control boxes serve as disconnects?
Answer: The IO 100, IO 101, and IO 102 boxes serve as disconnects. Question: Does the SQFlex have low water protection? Answer: Yes, a low water sensor is attached to the power cable one foot above the top. Question: What is the SQFlexs max lift?Answer: The 3 SQF-3 lifts up to 654 feet TDH (total dynamic head). Question: How is the TDH calculated? Answer: The TDH is the sum of. The vertical lift from the drawdown water level in the well up to the discharge.
The pipe friction loss in equivalent feet of head (see a Pipe Sizing Chart). The cut-out pressure, if there is a pressure tank in the system 1 PSI = 2.3 feet of. Question: What is the SQFlexs diameter? Answer: The helical rotor models are 2.9 inches, centrifugal models 3.9 inches. Answer: 2 years against defects in materials and workmanship.Question: Does the lightning arrestor need to be Grundfos made? Any lightning arrestor rated for the application will do. Question: Can the SQFlex run off batteries? The battery bank must be wired for at least 48 V. Amp draw of 8.4 A, the 3 SQF-2, 6 SQF-2, and 11 SQF-2 models are suitable.
Depending on TDH and desired flow rates. Runs of of 48V battery bank, PV direct, or 120V AC. Soft start assures compatibility with practically any true sine wave inverter 1000W or larger.
