The SQ pump is the basic model of the Grundfos 3” submersible pump range. With a wide range of performance parameters, you’re sure to find a model that will suit your individual requirements. Long and lean, this multistage pump is constructed of corrosion-resistant stainless steel, ensuring a long, reliable life. Only 3” in diameter, the compact design allows placement in small boreholes of the same size, or even 4” boreholes that have become smaller due to ochre deposits. Other pumps with similar capacities are usually 4” in diameter.
