Rotodynamic pumps -Design and performance analysis of axial flow pumps

As was the case with centrifugal pumps, each of the solutions we have just discussed is not unique, since the complete definition of a propeller pump leaves the operator free to choose a very large number of parameters. Each of the examples we have presented could have found a suitable solution by making other choices concerning flow speed, diameters, vane load, number of vanes, nominal incidence, etc. Those who have a wealth of experience in this field will be able to draw on the experience of their customers. Those with a heritage of propeller pumps will be able to introduce their own special features into the design.
