Details

Efaflu NBS 3” borehole pumps are designed for the extracting water from smaller boreholes and wells for water supply, irrigation, pressure boosting and lowering groundwater levels. Their compact 76mm diameter allows these submersible borehole water pumps to be used in 3inch boreholes, or 4inch that have become smaller overtime due to ochre desposits.

Thanks to the pump body’s AISI 304 Stainless Steel construction, these Efaflu pumps are constructed to withstand corrosion and offer a long, durable service life, whilst handling sand content up to 25g/m3.

For easier and more automated control over your borehole/well water supply and protection of the pump against things like dry running, overload and system pressure changes, we recommend looking at borehole pump control boxes.
