Grundfos SQFlex 1-8 submersible pump

The 4" SQF centrifugal pump is for low heads and large flow rates. A great low capacity windmill replacement pump. Here's the best bit, the SQFlex system allows a range of energy sources (AC 240V Power/Generator OR DC Solar/Wind) to be used without the need (or cost) of an inverter! Thanks to its flexible energy supply and performance, the SQFlex system can be combined and adapted to meet any need on the installation site with seamless switching between energy sources*. (*Automated if required with an appropriate controller). Talk to Bos Rural about kit form controllers customised to your requirements. Pump price only quoted, ask us for a wired kit price now.

SQF 1-8

The 4" SQF centrifugal pump is for low heads and large flow rates.

The SQFlex system is a reliable water supply system based on renewable energy sources, such as solar and wind energy. Thanks to its flexible energy supply and performance, the SQFlex system can be combined and adapted to meet any need on the installation site.

The SQFlex system has a wide voltage range, built-in maximum power point tracking (MPPT) as well as dry-running, voltage and overload protection.
