Hydropower Technology

Hydro mechanical equipment

We supply weir gates, shut-off and flushing gates, as well as trash rack cleaning solutions in various designs with a special focus on applications in small hydropower plants. Particular emphasis is placed on very robust, reliable designs that form the basis for long-term, successful plant operation.

Weir gates

We supply weir gates with hydraulic drive, in which a reliable, externally powered, independent safety device can be integrated through a mechanical emergency float system. 

Additionally, a special version is offered in which the drive cylinder(s) is positioned outside the discharge cross-section. For smaller dimensions, a system is also available where a fully pre-assembled assembly is delivered, providing various advantages on the construction site and resulting in significant cost savings.
