Grundfos SQFLEX AC/DC Submersible Solar Bore Pumps

Experience sustainable water pumping with the Grundfos SQFlex series — a versatile range of AC/DC-powered submersible bore pumps designed for remote, off-grid, and energy-conscious water supply applications. Equipped with a built-in inverter and variable frequency drive, SQFlex pumps run efficiently on solar, wind, battery, generator, or mains power — automatically adapting to the energy source available.

Choose between helical rotor or centrifugal impeller models to suit your required head and flow rate. With high-speed models now available, the Grundfos SQFlex range provides improved performance and flexibility for solar water pumping systems — ideal for properties with varying sun conditions or intermittent power.

SQFlex pumps are perfect for:

  • Off-grid farms and agricultural irrigation
  • Stock watering and tank filling
  • Domestic water supply in remote homes and cabins
  • Conservation areas, lakes, ponds, and wildlife reserves
  • Public institutions in rural regions (schools, clinics, etc.)

With extremely low operating costs, proven reliability, and free Australia-wide shipping, the SQFlex range is your complete renewable energy pumping solution.
