The Grundfos SQN 5 Series is a high-efficiency 3" submersible bore pump range designed for low-yield bores and domestic water supply applications requiring high performance in compact spaces. Built with multi-stage impellers and powered by a permanent magnet motor, the SQN 5 offers a reliable and energy-efficient solution with excellent hydraulic capability and a maximum flow of up to 120 LPM.

Constructed for narrow bores and applications where larger 4" pumps cannot fit, the SQN 5 is ideal for installations with restricted space. The pump incorporates built-in electronics that provide comprehensive motor protection features, including soft start, dry-run protection, upthrust protection, and over/under-voltage safeguards. Its floating impeller design ensures superior wear resistance, even in sandy or abrasive environments.

This series is designed for easy drop-in installation and long-term reliability, delivering consistent performance with low maintenance demands.

APPLICATIONS

• Groundwater supply from low-yield bores – ideal for domestic housing, lifestyle properties, or stock watering
• Pressure boosting and tank water transfer
• Remote water supply systems using generators or inverters
• Light agricultural irrigation or frost protection
• Environmental sampling or dewatering
• Where 3" bores preclude use of standard 4" submersibles
