positive new Pelton runner design was developed and
patented by EFG and has been in existence for almost
two decades now.
This design of specially shaped, modular parts that
lock onto each other is the secret behind the Pelton
runner built by EFG. This method is called the "interlocking
structure Pelton wheel".
Continuous research and development on this technology
allow us to produce a completely forged runner.
Both the individual bucket and the two discs, as well
as the clamping systems are forged. By drop forging
the individual runner blades a maximum of quality
can be reached and the highest security standards
in the area of hydraulic plants can be fulfilled.
EFG runners that were produced in this new way of
construction can be adapted respectively adjusted
both to new plants as well as for replacement runners.
Thanks to an innovation in the production cycle linked
with the drop forging- and processing technology,
the delivery time can be drastically reduced.
