Fishfriendly pumps

The patented fish-friendly pump allows more than 97 percent of the fish and even 100 percent of
the eel to pass through the pumping station unscathed. The fish-friendly pump was developed
in response to the adverse effects of conventional pumps in pumping stations on the fish stock. A substantial part of the fish mortality is caused when fish collide with the impeller blades and/or guide vanes when passing through conventional pumping stations. Furthermore conventional pumps greatly interfere with the innate migration of fish, and the eel population is especially threatened.
