Grundfos SQ 1-65 Submersible Borehole Pump

Purpose-built for narrow boreholes and domestic to small-scale groundwater systems. The Grundfos SQ 1-65 is a compact 3" submersible borehole pump designed for domestic water supply, irrigation, pressure boosting and other groundwater applications. Its slim stainless-steel construction allows installation in 3" boreholes and larger while keeping a small footprint in the well.

• Reliable motor performance — high-efficiency permanent magnet motor (0.70 kW) for consistent operation on a 230V single-phase supply.
• Performance range — delivers flow rates up to 1 m³/h and a maximum head up to 65 m, suitable for many domestic and irrigation needs.
• Protection and soft start — built-in dry-run protection, soft-start technology, and overload/voltage protection reduce wear and help preserve pump life.
• Durable construction — stainless-steel materials resist corrosion for groundwater use and continuous or intermittent operation.

Compact, efficient, and protected by integrated controls, the SQ 1-65 is specified where space is limited but reliable borehole pumping is required. Its combination of a slim 3" body, permanent magnet motor and protective features makes it suitable for a range of domestic and small-scale irrigation or pressure-boosting installations.
