Design a Low Specific Speed Dry Pit Solids Handling Pump With Pure 3-D Computational Fluid Dynamics Virtual Testing

Abstract

A relatively low specific speed dry pit solids handling pump was designed from scratch with pure 3D CFD virtual testing. In-house codes were used to provide preliminary design of the impeller, volute, etc. The 3D CFD tool Simerics-MP+ was employed for improvement of the design to achieve the desired pump performance. The virtual tests covered a wide range of flowrates from 40% to 130% of the best efficiency point (BEP). Final physical testing shows the CFD predictions are in good agreement with the measurements.
