Lobe pumps are widely used for transportation of high concentration and viscosity liquid of the medium through a pipeline if the requirements are simple head and discharge. Pump design is simplified by the development of Computational Fluid Dynamics (CFD) and complexity profile lobe pumps can also be predicted. Various parameters affect the performance of the pump. Time and position of the rotating rotor, rotor size and shape of the room is the most important parameter that should be considered to achieve high efficiency. In this project, the performance profile of the pump rotor lobe has different geometric curves which can be carefully evaluated. The investigation focuses mostly on the performance characteristics of the pump. At this time, the effect lobe pump rotor profile and lobe pump characteristics are not fully understood. Thus, the methods of numerical simulation and experimental verification are used to study the effects of existing internal vortex pump lobe. The internal flow field and characteristics of lobe pump with five design different rotor profile design simulation and forecasting in stable condition by using Autodesk Simulation CFD 2016 Standard k-ε turbulence model and PISO algorithm was used to solve the equations. In this report, numerical analysis was carried out at 1400RPM, 2400RPM, 3400RPM, and 4000 RPM and a change in head and efficiency were investigated. The results show that through the analysis of the flow rates for the optimum design of the lobe pump, the higher the volume flow rate of the rotor profiles will generate higher efficiency of the lobe pump in terms of its performance. The five designs rotor profile designs have their own compromises between their performance (volume flow rate) and its durability (life-span) of the lobe pump. Through this study, it can be concluded that the existing design is the most optimum because the application purposes require more durability over performance. In general, those applications that require more performance (volume flow rate) over durability (life-span) will choose Design A and if the application purposes require balanced between the performance and also the durability will choose Design D of the rotor profiles.
