The Grundfos SQN 3 Series is a high-performance range of 3" compact submersible bore pumps engineered for low-yield bores requiring dependable flow rates of up to 70 litres per minute. Designed for residential, agricultural, and environmental use, these slimline pumps deliver efficient water supply and long service life, even in narrow or deep installations.

Built around a robust multistage centrifugal design with floating impellers and tungsten carbide/ceramic bearings, the SQN 3 range ensures smooth and wear-resistant operation. A powerful permanent magnet motor with integrated protection features offers exceptional energy efficiency while guarding against dry running, overload, voltage fluctuations, over-temperature, and upthrust.

These plug-and-play pumps are suitable for both continuous and intermittent operation and are ideal for groundwater extraction, tank transfer, pressure boosting, or rural water schemes where bore conditions are limited or unstable.
