Manufacturing process

The impeller for the vertical RIVA Centrifugal Pump was scanned with a FARO laser directly at the production plant; subsequently, in about a week, the STL processing file was processed with a 3D manipulation program that allowed us to obtain all the useful measures to reproduce the impeller as per the original sample, thanks also to a further control of measures, tolerances and clearances by the maintenance manager.

Originally made of AISI 304 steel, the impeller is produced using DUPLEX steel thus being able to guarantee greater wear resistance corresponding to grade 4A. After defining all the measures, the tools useful to produce the foundry blank were implemented; subsequently the molten raw material was deburred, treated and sandblasted, with a preparation time from the dimensional survey of 45/60 days, and then moved on to a final processing phase on machine tools and finally delivered to the customer packed in 90 days.
