In our monobloc casting processes, 3D printed sand mold is used so that the crown, the band and the blades can be poured at the same time. The flow surfaces are polished and the outer surface of the crown and the band are machined. The runner is of high degree of precision, stiffness, abrasion resistance and safety.
The cost of a monobloc Francis runner is reduced by 10% compared to that from a welding combined one. And the production period is also reduced by about 30 days.
We can provide the whole set of Francis runners with the diameter of 1900 mm and height of 950 mm. The maximum weight of the runner can reach 8000 kg.
