Fish Friendly Screw Pumps – low-head drainage and flood defence
Fish Friendly Screw Pumps are designed for low-head water movement, transferring water gently with minimal turbulence. Specially shaped impellers allow safe fish passage, supporting aquatic biodiversity. Pumps handle water with debris and solids, reducing blockages compared to submerged types. Variable speed drives improve energy efficiency and lower running speeds. Installation requires only a horizontal apron and vertical wall.
