With a wide range of performance parameters, you’re sure to find a model that will suit your individual requirements.  \nLong and lean, this multistage pump is constructed of corrosion-resistant stainless steel, ensuring a long, reliable life. Only 3” in diameter, the compact design allows placement in small boreholes of the same size, or even 4” boreholes that have become smaller due to ochre deposits. Other pumps with similar capacities are usually 4” in diameter.  \nThe SQ single high-speed pumps are ideally suited for a variety of applications:  \n• Domestic water supply  \n• Small water works  \n• Irrigation  \n• Groundwater lowering  \nPermanent magnet motor  \nA series of unique features make the SQ series very easy to install and operate, and ensure a reliable water supply at all times. Thanks to its’high-speed permanent magnet motor, it offers a very high performance in relation to its compact design.  \nThe motor enables the SQ to pump water from a borehole to a depth of 238 metres.  \nThe special SQN pumps are engineered in an even higher grade of stainless steel for applications with slightly aggressive liquids.  \nYears of reliabilitY  \nThe individual models of the SQ series are composed of high-quality stainless steel. Combining this with a robust internal construction and sturdy impellers provides the user with years of reliable operation.  \nProtection against drY running  \nDry running is one of the most disastrous situations a pump can experience. The absence of liquid can cause the pump shaft to seize up, initiating the burn out of motor windings, unless the power is switched off. In case of dry running the SQ pump automatically switches off.  \ngrundfossq/sqn  \n– an outstanding solution  \n• Soft start reduces wear on motor and prevents spikes in electrical demand  \n• high starting torque, even at low supply voltage  \n• Overload protection protects motor from unstable voltage supplies  \n• Dry running protection safeguards against damage from an absence of liquid  \n• Automatic re-start ensures a reliable water supply following preventative shutdown  \n• 100% stainless steel construction provides durability and peace-of-mind  \nTechnical information  \nPerformance range: Flow up to 9m3/h (SQ/SQN 7), Head up to 238 m (SQ/SQN 1)  \nNominal voltage range: 1x200-230V  \nFrequency  \n(of the voltage supply): 50/60Hz  \nMax. acceptable media temp: 30°C (40°C)  \nPump diameter: Ø74mm  \nWeight (min./max.): 4.7-6.4 kg Thread connections: RP 1¼ / RP 1½  \nMinimum well diameter: Ø76mm  \nMaterials (Stainless steel): SQ-DIN W.-Nr. 1.4301, AISI 304, SQN-DIN W.-Nr. 1.4401, AISI 316  \nThe SQ/SQN pumps can be installed vertically or horizontally.","cbCaitTSQgjIE0ID","https://ap.wps.com/l/cbCaitTSQgjIE0ID","pdf",752857,"English","# Applications\n## Domestic water supply\n## Small water works\n## Irrigation\n## Groundwater lowering\n# Key Features\n## Permanent magnet motor\n## Corrosion-resistant stainless steel\n## Dry-running protection and automatic re-start\n# Technical Information\n## Performance range\n## Voltage and frequency\n## Media temperature\n## Dimensions and materials","[{\"question\":\"What is the main purpose of the GRUNDFOS SQ and SQN pumps?\",\"answer\":\"They are designed to meet water supply needs by pumping water from boreholes with reliable performance and corrosion-resistant construction.\"},{\"question\":\"How do the pumps protect against damage from dry running?\",\"answer\":\"In dry running, the SQ pump automatically switches off, preventing severe pump outcomes like shaft seizure and motor winding burnout.\"},{\"question\":\"What are the performance and operating specifications for the SQ/SQN range?\",\"answer\":\"The range provides flow up to 9 m3/h (SQ/SQN 7) and head up to 238 m (SQ/SQN 1), with nominal voltage 1×200–230 V and supply frequency 50/60 Hz.\"}]","GRUNDFOS SQ/SQN - an outstanding solution | PDF",1790447015]
