With increasing demand of vacuum pump also require high performance of pump demanded by market. Vacuum pump to give their function properly but many vacuum pumps not give work properly as per requirement just because of poor design of vacuum pump. So design of pump being changed to improve function, but it is costly and time consuming using experimental work. So CFD analysis use for this purpose. The main objective of this project is to improve vacuum level of water ring vacuum pump. In Fine tech engineering during testing process of water ring vacuum pump see that in WRVP the vacuum level is very low as per requirement and therefore efficiency is low. To improve the efficiency of SV-20 water ring vacuum pump, Computational Fluid Dynamics analysis is one of the advanced tools used in the pump industry. A detailed CFD analysis is used to predict the flow pattern inside the impeller which is an active pump component. From the result of CFD analysis, vacuum level of impeller is justified and validated with experimental result here with very low deviation in result of 2.24%. Now modified impellers are modelled using CAD modelling software. Here we changed thickness of blade, inlet and outlet angle of impeller based on empirical relation and literature. Here 11 modified impellers remodelled. These models are analysed individually using CFD analysis to fing the performance of the modified impeller WRVP. By using CFD analysis impellers with the improved value of vacuum level 485.88mm of hg vacuum get and by means improved efficiency achieve. Key word :Vaccum pump,CFD,Impeller,Blade Thickness.
