Pumping stations play a key role in communities that want to maintain a dry environment and prevent flooding. When water levels get too high, these pump stations are a threat to fish migrating upstream or downstream, as fish often cannot get through the pumps without suffering serious physical harm or even losing their lives along the way.

 

Flowserve Hydraulic engineers have developed and tested patented fish and eel safe pump designs in accordance with Dutch Standards Institute (NEN) 8775 to maximize pass and survival rates while maintaining optimal pump performance and efficiency.

 

Flowserve patented features include:

 

An impeller with an external upright edge along the blade

The shell is terraced to prevent aquatic life from being trapped

A diffuser bend with a hyperboloid diffuser blade ensures the highest efficiency achievable, avoiding cutting/cutting of fish or eels as they leave the impeller
