Hydropower is the very traditional market of CARCO with the first seals supplied more than 1 century ago for the water power stations in the Alps.
In the long run the seal variety has grown a lot and today the hydropower seal package comprises different profiles and materials for:
- Kaplan, Francis and Pelton turbines;
- Spherical and butterfly valves;
- Servomotors;
- Gate wheel bearings;
- Gate hydraulic cylinders.
CARCO’s technical department can also recommend the correct guiding made of water lubricated materials.
The “ISP” and “VSP” technologies enable the gluing and hot joining of split seals on site, to avoid costly dismantling of parts of hydropower machineries.
