Hydro – power plants

ŽĎAS is supply company, which main activities consist of complete supplies of mechanical equipment and follow technology.

Delivery of  hydropower plants equipment, i.e. hydraulic turbines of all types and sizes, incl. elaboration of basic and detail design documentation, erection and guarantee measurements at site, is the new part of our supply.

Our team located in Blansko continues with a long-time experience in research and fabrication of hydraulic turbines in this city. Great emphasis is laid on high quality hydraulic and mechanical design of our machines. The state-of-the-art CFD and FEM computation methods are applied to optimize particular components and to complete hydraulic machines to assure high efficiency and lifetime without any operation problems. Modern, cavitation-proof and environmental-friendly materials are used in the machine design.



  • Rehabilitation of existing hydromechanical equipment of hydropower plants according to new standards and customer requirements.
  • Delivery of new hydraulic machines with high level of efficiency and durability (greenfield projects).

Fields of activities

  • Research and development of hydraulic machines (outsource)
  • Basic design and Detail (Manufacturing) design
  • Complete in-house manufacturing
  • Erection, supervision of erection and manufacture
  • Individual and complex tests at site
  • Commissioning, guarantee and diagnostic site measurements of hydraulic machines

Basic and Detail design:

  • Creation of technical documentation of mechanical part of Hydropower technology
  • Determination of critical load at transients in hydraulic systems of hydro power plants
  • Creation of Detail documentation (manufacturing documentation) of designed hydraulic machines
  • FEM analysis of hydraulic machine main parts
