Grundfos SQ 1-140 Submersible Borehole Pump

Designed for deep domestic and agricultural water applications, the Grundfos SQ 1-140 is a 3" submersible borehole pump that delivers up to 1 m³/h at heads as high as 140 m. Its compact stainless-steel construction and permanent magnet motor make it suitable for installation in narrow boreholes while providing the pressure required for irrigation, pressure boosting, and groundwater extraction.

• High head and measured flow: Up to 140 m maximum head and up to 1 m³/h flow for deep-well use.
• Efficient motor: 1.68 kW permanent magnet motor on a 230V single-phase supply for consistent performance.
• Robust materials and fit: Stainless-steel construction and a 3" form factor for narrow borehole compatibility.
• Built-in protections: Dry-run protection, soft-start technology, and overload/voltage protection to reduce wear and support reliable operation.

The SQ 1-140 combines a compact footprint with features aimed at reliable deep-bore operation. Use it where a high-head, narrow-diameter submersible solution is required for domestic water supply, irrigation, or pressure-boosting systems.
