They are used for relatively low quantities of water with high heads up to 1000 meters. Efficiency and performance definitely remain constant, independent of whether conditions it is used in mountain regions or as storage power station.
HPDM axially split volute pumps are tailor-made and are extensively used to transport large volumes of liquid over long distances and high geodetic heights as in water and oil pipelines. They are available in single stage or various multistage configurations with single- or double suction impellers.
With their rather unique construction, our smaller direct coupled BEVI generators are designed and built at our factory in Blomstermåla. Hydropower generators are built in many different styles up to a few MVA and with special adaptations to the turbine.
The new range of the Landustrie screw pump covers the hydropower screw turbines. 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.
