This paper aims to tackle the problem of designing an optimally efficient impeller for SUBMERSIBLE TURBINE PUMP (being developed first time in India under the ‘Make In India Aatmanirbhar’ scheme by Govt. of India) while taking into account several factors like the material of the impeller and its components. The paper suggests a mechanical solution to the problem that is practical and efficient, involving a constructive overview of the design process of each component in the impeller –the number of vanes and the outlet angle, the shut-off head, the diameter, the width, the eye diameter, the shaft diameter and more. This paper presents the construction and function of each component of the proposed system and illustrates the same using graphs and three-dimensional computer-generated models. It also takes into account the effectiveness of the material used in the construction of the impeller, whilst articulating safety requirements and ensuring that the design abides by them. Finally, it concludes by summarizing the effectiveness of the proposed design specifications.
