STUDY OF THE EXISTING DESIGN OF IMPELLER OF 4” SUBMERSIBLE PUMP AND IMPROVING IT’S EFFICIENCY USING CFDA THROUGH THEORETICAL ANALYSIS

“Harson Pumps and Motors” a company that manufactur es high quality submersible pumps of various sizes and capacity. This project deals with the modification in the existing design of radial flow impeller made out of plastic material i n many cases may be called rotor. By modifying the design of impeller either by changing the blade angle or by changing the width we could achieve a considerable increase in the output discharge whi ch will be shown in the further work. Ansys software is used to analyze the performance of pump and the equivalent output of the new impeller design and use Pro-e for the design of impeller. Af ter modeling the impeller we will calculate the equivalent theoretical efficiency so as to prove that the impeller that is designed newly is of better design than the previous one. The sole objective of this project is to increase the efficiency of the submersible pump by increasing the net output discharge. The pump in which we are modifying the design of impeller is 4” submersible pump.
