Grundfos SQ 3-105 Submersible Borehole Pump

Purpose-built for deep domestic and irrigation supply, the Grundfos SQ 3-105 delivers up to 3 m³/h at heads to 105 m from a compact 3" submersible design. The pump’s 1.85 kW permanent‑magnet motor runs on 230V single‑phase power and is engineered for narrow boreholes where space is limited.

• High head and steady flow: Up to 105 m maximum head and flow to 3 m³/h for deep well extraction and pressure-boosting tasks.
• Compact stainless construction: 3" stainless steel pump body suited to narrow boreholes and corrosion resistance where applicable.
• Efficient motor and protections: 1.85 kW permanent‑magnet motor with built‑in dry‑run protection, soft‑start to reduce motor stress, plus overload and voltage protection.
• Power supply: Designed for 230V single‑phase installations.
• Application versatility: Specified for domestic water supply, irrigation, pressure boosting and deep borehole systems.

Compact form, motor efficiency, and integrated protections make the SQ 3-105 suited to installations that require deep extraction from narrow boreholes while maintaining steady flow and motor longevity.
