Impeller Design

3.2.3 Floating versus Fixed Impeller Pumps. Floating impellers are free to "float" axially (move up and down relative to the pump shaft) because they are not fixed to the pump shaft in the axial direction. As shown in Fig. 3.5, impeller hubs are not stacked so there is a vertical distance between the successive hubs.
