The Fish-Friendly Screw Pump is a revolutionary water pump designed specifically to ensure safe fish migration in water management systems. Unlike conventional axial pumps that pose a threat to aquatic life due to turbulence and injury risks, this pump operates via a screw enclosed within a rotating cylinder, minimizing turbulence and eliminating injury risks. Available in various diameters ranging from 0.8 m to 5.0 m, it has the capacity to handle up to 10 m³ per second.

One of the key innovations of this pump is its fish-friendly design, which allows fish to move through the pump unimpeded by blades or screens, ensuring 100% fish safety. The pump is built from durable materials, requiring low maintenance and offering a long service life, making it an ideal solution for water management in polders, pumping stations, and hydropower systems.

Its design also allows for flexible installation and integration, aligning with both ecological and operational priorities. By combining fish protection with high hydraulic efficiency, the Fish-Friendly Screw Pump embodies FishFlow’s mission of sustainable water infrastructure that respects aquatic life while supporting reliable water movement.
