Grundfos SQEN 1 Single Phase 3" Submersible Bore Pumps with Variable Speed (Max 30LPM) ‐ 32 mm Discharge

Note: all variants include the complete pump, motor and 1.5m cable

The Grundfos SQEN1 Series is a compact, high-performance range of 3" submersible borehole pumps designed to deliver consistent and efficient water supply in narrow or low-yield bores. Featuring variable speed operation and built-in intelligent control, these pumps automatically adapt to changing demand and are ideal for domestic water supply, pressure boosting, tank filling, and low-yield groundwater applications.

Each SQEN pump is equipped with a permanent magnet motor for exceptional efficiency and speed modulation, while the integrated electronics enable communication with a Grundfos CU 301 controller (or compatible systems) for constant pressure operation. Soft start-up reduces wear on components, and multiple layers of built-in protection – including dry-run, overload, over/under-voltage, over-temperature, and upthrust protection – ensure long-lasting, maintenance-free performance.

With their slim 3” design, floating impellers, and wide voltage tolerance, SQEN pumps are perfect for retrofitting into narrow bores or replacing older systems with modern, intelligent water supply solutions.
