If you want to suspend solids, the best advice is to not have a vortex.  For solids suspension, you want  baffles or an angle-offset mounting to minimize or eliminate the vortex.  If you have a vortex on the surface, you will likely have a pile of solids in  the middle on the bottom.  Your agitator should pump downward to sweep the solids off the bottom.
