Francis runner
Francis runner material could be stainless steel or carbon steel. The upper crown, lower ring, and blades are partial casted, polished, and then welded together. After heat treatment and fine polish, the factory tests including static and dynamic balance test, UT test, and dimension measurement. Our runners are guaranteed 100% all parameters meet the requirement, and related regulation.
