The Grundfos SQ series is a line of compact submersible pumps designed specifically for clean water extraction and residential water supply systems. Built for reliability and efficiency, these pumps are a go-to choice for plumbers and installers working on private wells, boreholes, and municipal water connections. The series covers a range of models, from the SQ 2-55 to the SQ 5-70, ensuring you have the right pump for every flow and head requirement.

Key Features for Installers

Installers appreciate the SQ series for its straightforward design and robust build. Each pump is a slim 3-inch submersible unit, making it easy to handle in tight boreholes. The integrated dry-run protection and thermal overload safeguard the motor during unexpected issues. The pumps run on standard 1x230V power at 50/60Hz, which matches most residential and light commercial electrical setups. You will also find models with pre-attached 30-meter cables, saving you time on site.

Performance and Power Options

The SQ lineup offers flexible power ratings to match your project needs. Choose from 0.70 kW, 1.15 kW, or 1.85 kW motors depending on your required water flow and lift height. Models like the SQ 2-70 and SQ 3-55 deliver steady pressure for single-family homes, while the SQ 5-70 and SQ 3-105 handle higher demand applications. Whether you need a standard unit or a basic package kit like the SQ3-40 PAKIET PODST., the series provides consistent performance across all water supply network connections.

Easy Installation and Maintenance

Time is money on every job, and the SQ series is built to keep you moving. The compact 3-inch diameter fits standard boreholes without extra casing work. The pumps are fully submersible, which means better cooling and longer motor life. Basic maintenance is minimal thanks to corrosion-resistant materials and sealed components. If you are working on water supply networks and connections, these pumps integrate smoothly with standard pressure tanks and control systems without complex wiring or adjustments.
