We all know the traditional application of the archimedean screw pump where water is pumped up from a lower to a higher level. 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.

We all know the traditional application of the archimedean screw pump where water is pumped up from a lower to a higher level. 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
In Switzerland, Hirschthal, a hydropower screw has been recently installed. The screw details are: dia. 2.8m, length 10m, capacity 3500 l/sec. power 110kW, head 3.5 m.
