Looking for a reliable 220V borehole pump? We stock tested 4″ submersible sets.
The Olbin 4SDm3 single-phase series is a 4-inch submersible borehole pump set supplied as pump + motor with a surface control box for 220V models.
Noryl impellers reduce load and resist corrosion.
Furthermore, stainless-steel wetted parts extend service life. For higher head or long runs, consider the three-phase range; however, for most homes the 220V set is the practical choice.
We stock and support 220V borehole pump sets countrywide.
