Grundfos SQ 1-125 Submersible Borehole Pump

The Grundfos SQ 1-125 is a 3" submersible borehole pump designed for domestic water supply, irrigation, pressure boosting and deep borehole systems. It delivers up to 1 m³/h flow and a maximum head of up to 125 m, driven by a 1.68 kW permanent magnet motor that supports narrow-bore installations where space is limited.

• High head performance: up to 125 m for deep wells and elevated pressure needs.
• Compact 3" design: fits narrow boreholes and simplifies installation in tight wells.
• Efficient permanent magnet motor: 1.68 kW power for sustained pumping up to 1 m³/h.
• Durable stainless-steel construction: resists corrosion in groundwater applications.
• Built-in protections: dry-run protection, soft-start technology, and overload/voltage protection for reliable operation.

Specifically suited for continuous or intermittent operation in domestic and irrigation contexts, the SQ 1-125 combines compact dimensions with high head capability and integrated motor protections to meet common borehole pumping needs.
