The new hydraulic system is based on the proven SEZ. Its optimised impeller geometry and reduced number of diffuser vanes allow fish to pass through with hardly any damage. Even sensitive species such as bream survive the passage with a mortality rate of under ten percent. The pump set raises the bar for sustainable hydraulic engineering and also meets the high requirements on flood control.
Keeping bodies of water ecologically connected has long been a hot topic in Europe. Migratory fish such as eel or trout experience structural barriers that endanger their life cycles. Drainage stations and pumping stations that are indispensable for flood control often form deadly traps for these species.
The SEZ F pump with its fish-friendly hydraulic system is a contribution to taking on ecological responsibility and future-proofing hydraulic engineering infrastructure. Visitors to IFAT 2026 can see for themselves in Munich how impressive this innovation is.
The IFAT 2026 will take place in Munich from 4 to 7 May.
