Grundfos SQ 3-30 Submersible Borehole Pump

The Grundfos SQ 3-30 is a compact 3" submersible borehole pump engineered for domestic water supply, irrigation, pressure boosting and groundwater systems. It delivers up to 3 m³/h flow and can develop heads up to 30 m, driven by a 0.70 kW permanent magnet motor on a 230 V single-phase supply.

• Compact 3" design: fits narrow boreholes while allowing installation in tight wells.
• Performance: up to 3 m³/h flow and up to 30 m maximum head for typical domestic and light irrigation needs.
• Efficient motor: 0.70 kW permanent magnet motor for lower energy draw compared with conventional induction motors.
• Durable construction: stainless steel components resist corrosion in groundwater applications.
• Built-in protections: includes dry-run protection, soft-start to reduce motor wear, and overload/voltage protection for reliable operation.
• Operation: suitable for continuous or intermittent use.

This pump combines a slim profile with motor and protection features that support steady water delivery in narrow boreholes. Specifications above describe the product’s verified capabilities and typical use cases.
