Product Details

Grundfos is one of the world's largest manufacturers of pumps, providing water for homes, farms, commercial buildings, and industrial uses. Featuring unique stainless steel construction and the latest in electronics, Grundfos pumps are recognized for reliability and value throughout world-wide -- wherever water moves. Grundfos maintains an extensive network of manufacturer representatives, distributors, and dealers to serve customers nationwide. SQFlex pumps The complete SQFlex pump range consists of 7 different pump sizes: 4 centrifugal and 3 helical rotor pumps. All pumps are fitted with the same size motor which, together with the new sizing tools, makes system sizing simple. The SQFlex system is a reliable water supply system especially suitable for remote locations not connected to the electricity supply grid. The SQFlex system is equipped with the SQF submersible pump. 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.

TDH Range (Ft.): 40 - 300 Nominal GPM: 11 Length (In.): 99 Output Size: 1 1/4" 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. The optional system components are: * SQF submersible pump * CU 200 control unit * IO 100 and IO 101 switch boxes * IO 102 breaker box * Energy supply: o solar panels o wind turbine o generator o batteries Features of the Grundfos 11 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. The 3 in. diameter allows the pump to go in installations where others can't. Centrifugal Pump (4"): Based on Grundfos' 40 years of experience in submersible pumps, these models are capable of providing high flows, up to 80 gal/min, at moderate heads. Materials: All Stainless steel for long pump life. Motor: Only one motor size covers the entire pump range. Designed for peak efficiency and complete reliability, the motor features integrated electronics, eliminating the need for complicated external controls. 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. Enclosure class IP 68. 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) minimum 1500 W (centrifugal 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 3 SQF, 6 SQF, 11 SQF: Minimum: 3 in. 16 SQF, 25 SQF, 40 SQF, 60 SQF: Minimum: 4 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: ø0.090 in. 16 SQF, 25 SQF: ø0.10 in. 40 SQF, 60 SQF: 0.16 in x 0.80 in.
