STEEL CASTINGS
FOR
HYDROELECTRIC
POWER PLANTS

SAFAS is one of few foundries in the world capable of producing Francis runners, even of big size, completely cast in one piece. Thanks to a business unit expressly dedicated, SAFAS can offer:

  • Patterns, according to foundry
    requirements, manufactured
    starting from the supplied drawings.
  • Steel refining in the AOD that
    guarantees mechanical
    characteristics definitely higher
    than the standard ones.
  • Rough machined castings with            tolerated allowances and guarantee of     the inherent quality.
  • Finishing of the hydraulic profiles
    by CNC machine tools followed by
    grinding, polishing and balancing            for the runners.

  • Particularly accurate dimensional            checks, even by means of 3D
    laser check systems
  • Casting inspection according
    to the more widespread standards
    and to the customer’s technical
    specifications with ISO
    EN10204.3.1B certification.

The experience of more then 40 years in the hydro market allow us to produce monolithic Francis runner with a diameter up top 3.500 mm in fully grinded condition with the full respect of the dimensional prescription.
