FB Submersible pump - FB8RA/10 8'' - Cast Iron
8'' radial cast iron submersible pump for clean water - DN200 - Maximum Flow Rate 750 l/min - H(m) 118 - Motor to be added: recommended FB 6F35 3~400 (35 HP – 26 kW) or compatible
PRODUCT CODE: FB8RA/10FB radial-flow submersible pump end, FB8R series, in cast iron, for clean water in 8” wells (DN 200). The stages with limited axial size provide high heads with medium-low flow rates.
Cast iron impellers make the range robust and suitable for deep wells, with the highest safety of the installation and high efficiency.
