Definitions

  • Draft tubes have the advantage that they allow the impeller to be located in the upper portion of the tank, thereby reducing shaft length and whip as well as the mass of the system.
  • the impeller is generally free from settled solids so that starting of the impeller is facilitated.
  • the diffusion vanes may be mounted within a centrally located mounting boss which is located below the impeller.
  • the angular orientation of the diffusion vanes may be substantially vertical, but this orientation will, eventually, depend on the application to which the mixer of the invention is to be put, since a mixing flow other than a purely axial flow may be required in certain applications.
