The new SEZ F, featuring fish-friendly hydraulics, combines advanced fluid dynamics with a proven fish-friendly operating mode. An optimized 3D flow path, supported by state-of-the-art CFD simulations, minimizes turbulence and shear stress zones, thereby enabling even sensitive fish species to pass through unharmed and in a manner appropriate to their species. At the same time, the pump meets the highest requirements in pumping stations and flood protection systems. This new generation of the SEZ F pump sets a new standard in terms of ecology, sustainable resource management, and engineering precision. Technological innovation thus becomes a measurable contribution to healthy, vibrant, and permanently interconnected aquatic ecosystems.
