Pump's hydraulic system unites flood control with fish protection
©KSB SE & Co. KGaA The hydraulic system of the new fish-friendly KSB tubular casing pump called SEZ F 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. www.ksb.com
