The Grundfos SQN 1 Series is a compact and efficient 3" submersible bore pump range engineered specifically for low-yield bores and narrow-diameter wells. Designed with built-in motor protection, permanent magnet motors, and advanced hydraulic design, these pumps are the go-to solution for domestic water supply, rural pressure systems, and tank transfer in limited space conditions.

Despite their small size, SQN 1 pumps deliver up to 30 litres per minute and heads reaching 155 metres, making them ideal for installations where both space and yield are restricted. Each model incorporates floating impellers with tungsten carbide/ceramic bearings for superior wear resistance and soft start technology to minimise mechanical stress and reduce energy spikes on startup.

Built-in protections against dry-running, upthrust, voltage fluctuations, overload, and overheating ensure long service life and reduced maintenance. Whether you're running a rural home, off-grid tank system, or monitoring groundwater in environmental applications, the SQN 1 delivers dependable performance in harsh Australian conditions.
