Kaplan Turbine

Noting that on a number of applications the VLH turbines were not necessarily the best solution for the site, we decided to develop a range of Kaplan conventional turbines, with vertical double or single adjustment as well as horizontal or inclined axial turbines, which we exclusively propose equipped with PMGA direct  drive generators.

Such turbines, based on a specific development for MJ2, and benefiting from its experience on very low heads and low speed generators, cover the following application range:

  • Gross head: from 2 to 5,5 m
  • Unit flow rates from 6 to 55 m3/s
  • Power at the generator terminals : from 200 kW to 2.000 kW

All the turbines are designed with spherical hubs and hemispherical turbine runner coatings guaranteeing optimal outcomes.

Such new offer has already demonstrated its relevance, with the production of 3 turbo – generator groups delivered in 2016 and 2017:
