The Grundfos SQN 7 Series is a high-performance range of compact 3" multistage submersible borehole pumps designed for high flow rates in domestic, agricultural, and light commercial water supply systems. With a maximum flow of up to 150 LPM and built-in motor protection, these pumps are ideal for low-yield bores, tank filling, irrigation, and pressure boosting applications.

Each pump is powered by a permanent magnet motor for high electrical efficiency and is equipped with floating impellers for maximum wear resistance, even in sandy water conditions. Soft-start functionality reduces start-up current and mechanical stress, while integrated dry-running protection, overload protection, and voltage safeguards ensure reliable performance in off-grid and remote installations.

The SQN 7 series is designed for easy installation and long service life, making it an ideal solution for systems requiring dependable water delivery at high flow volumes.
