Grundfos SQ 3-40 Submersible Borehole Pump

The Grundfos SQ 3-40 is a compact 3" submersible borehole pump engineered to deliver domestic water supply, irrigation, pressure boosting and groundwater pumping where a slim installation and steady performance are required. With a high-efficiency permanent magnet motor and stainless-steel construction, it combines a small footprint with capability up to 3 m³/h and 40 m head.

• Reliable output: Flow up to 3 m³/h and maximum head up to 40 m support typical household and light-irrigation needs.
• Efficient drive: 0.70 kW permanent magnet motor and 230V single-phase power for energy-efficient operation in compatible supply environments.
• Compact installation: 3" design fits narrow boreholes and larger, easing placement where space is limited.
• Durable construction and protection: Stainless-steel pump body with built-in dry-run protection, soft-start, and overload/voltage protection to reduce wear and help safeguard the motor.
• Flexible use: Suitable for continuous or intermittent operation in the listed applications.

Designed for straightforward borehole installations, the SQ 3-40 focuses on an efficient motor, corrosion-resistant materials, and protective features to support consistent water delivery in the specified applications.
