ABSTRACT:
The invention provides a centrifugal pump having an axial diffusor with plural blades having such a specific incident angle as to prevent appearance of revolving and stall of a treating liquid. An incident angle of the blades of the axial diffusor is selected so that the value obtained by subtracting from the blade incident angle a treating liquid incident angle is equal to or below a specific angle representative of the kind of treating liquids.
