          Figure 7.9. Some types of centrifugal pumps. (a) Single-stage, single suction volute pump. (b) Flow path in a volute pump. (c) Double suction
          for minimizing axial thrust. (d) Horizontally split casing for ease of  maintenance. (e) Diffuser pump: vanes V are fixed, impellers P rotate.  (f)
          A related type, the turbine pump.
