The screws epicycloidal profiling is developed through a complex computerised calculation which not only perfectly defines their shape, but also controls the production with continuous monitoring of machinery process, consequently assuring a high degree of repeatable quality.
The high quality level of these screw pumps is guarenteed by a final testing on 100% of the manufactured products.
