Industrial cases
Centrifugal, helical-centrifugal and axial-flow pumps: cavitation

In a pump and pump station project, the choice of (NPSH) _disp at the pump inlet determines the overall economy of the station and/or pump. The (NPSH) _disp is linked to the installation, not the pump.

When selecting a pump, it is necessary to define the following simplified technical specifications:

• the pump's operating flow area ;

• pump unit architecture (vertical/horizontal, suction, load, etc.);

• expected duration of use with frequency of use in each zone ;

• the nature of the fluid being pumped...
