4HP 4″ Borehole pumps

Series of submersible pumps 4″ newly developed, designed and built for maximum resistance against sand (up to 250 g / m³) and other impurities. Materials certified for use in drinking water that allow the pump to run dry without even deteriorate. The supports are made of steel AISI 304, obtained with casting process, ensure extreme robustness and reliability to the product. The check valve is integrated in the cylinder head to support the weight of the water column and for protection against water hammer. The use can be continuous and can work both vertically and horizontally.ù
