Gess - Screw Pumps - Brochure

The first screw turbine in the world was designed and manufactured in 1997 in the Czech Republic. The construction uses an ancient pump called the Archimedean screw in reverse operation. A worm turbine is a gravitational mechanical machine that converts the potential energy (slope) of a water flow into mechanical energy and subsequently, thanks to a gearbox and a generator, into electrical energy. Water from the water flow flows through the channel into the trough of the screw turbine, inclined at a certain angle. Due to its weight, it acts on the blades of the screw part of the turbine rotor and slowly rotates the entire turbine. The power of the turbine depends on the flow and slope of the water flow.
