We all know the traditional application of the archimedean screw pump where water is pumped up from a lower to a higher level. The reversal of its function provides an efficient means of saving energy. The main advantage of a screw pump is that it is taylor made to the specific installation and therefore extremely efficient for a wide range.

The new range of the Landustrie screw pump covers the hydropower screw. An efficient use of water power is already achieved at a level difference of 1 meter and a capacity of 500 l/sec. The largest capacity and level difference for hydropower screws is as much as 15000 l/sec. at 10 meter.

Benefits of hydropower screws:

highest efficiency (up to 86%)
simple installation
easy implementation in existing situations (no civil construction work)
extremely fish friendly
insensitive to clogging
low maintenance costs
long life time
improvement of water quality
24/24 energy supply
active flow control without extra losses
possibility to switch over to pump function
self-regulating to changing water flow
