The pumping tank or pump-box needs to be constructed for the CFD program. One of the beauties of CFD is that scale-up is not required, since you input the actual geometries. Here is an example of a Pumper Stage as a cylindrical vertical tank and its terminology. The shape of the tank can be virtually anything, including square tanks, commonly found in older SX plants.

These two figures show a straight bladed turbine, which is the easiest pumper to model. Any design of pumper can be modeled, for example a 6-bladed pumper with curved blades like the Lightnin R320 or the Philadelphia Mixers CBT-6. There is no literature data on these impellers. They must be determined. This could be done in small scale experimental studies with actual fluids, or as here with a CFD study. The design of the pumper blades is required, or they can be invented on the fly!
