Fish-friendly Archimedean Screw Pump - 100% fish safe pump, with high efficiency, long lifespan, low maintenance and impervious to debris

FishFlow Innovations' fish-friendly Archimedes' screw pump is a very high-efficiency pump for lifting water. Compared to conventional pumps, not only does it save a lot of energy, but it also saves the lives of countless fish that migrate through the pump. Indeed, migrating fishes have the possibility to pass through the displaced water to find their way out of the polder, but approximately 15% of all fish that utilise this transport route suffer some kind of damage in conventional screw pump. The FishFlow Innovations' screw pump has a design that does not inflict any damage on passing fish. The blades do not stretch across the full width up to the tip of the screw, instead the width of the blades gradually decreases from the middle outwards during the last few windings. The second adaptation concerns the housing of the screw, which is enclosed in a pipe that is attached to the screw and thus rotates together with it which also ensures no water leakage. These adaptations transformed the screw pump into a fish-friendly facility for downstream migration.
