Reverse engineering of centrifugal pump parts for production needs

The article presents a comprehensive study on reverse engineering of two key parts of the SP250TV pump: the impeller and the volute. In the context of import substitution and the need to develop domestic production of mining equipment, 3D scanning, calculations, and modifications of these parts were carried out. The reverse engineering process allowed for the creation of detailed three-dimensional models and the development of design documentation for subsequent production of Russian analogues. The article discusses the main stages of calculations and design, including the calculation of impeller parameters and spiral outlet of the volute, as well as their adjustment to improve operational characteristics. The resulting models and drawings are ready for implementation in serial production.
