Grundfos SQ 1-50 Submersible Borehole Pump

The Grundfos SQ 1-50 is a compact 3" submersible borehole pump engineered for domestic water supply, irrigation, pressure boosting and groundwater applications where a slim, high-efficiency unit is required. It delivers up to 1 m³/h and can develop heads to 50 m, making it suitable for narrow boreholes and moderate lift requirements.

• Compact 3" stainless steel construction for installation in narrow boreholes.
• High-efficiency 0.70 kW permanent magnet motor for reliable, low-energy operation.
• Rated for 230V single-phase power supply and capable of continuous or intermittent operation.
• Built-in protections including dry-run protection, soft-start to reduce motor wear, and overload/voltage protection.

Use the SQ 1-50 where a space-saving submersible pump is needed for household water systems, small-scale irrigation or pressure boosting. Its stainless-steel build and motor protections focus on service reliability while the motor and performance range support consistent delivery up to the specified flow and head limits.
