Should pump users care about axial thrust?
Normally the user shouldn’t have to care about axial thrust. Pump failure from an axial thrust-related problem is relatively uncommon. But very few, if any, pumps are entirely immune to...

What is the Purpose of Minimum Flow?
Over the years use of the term “minimum flow” has evolved. Decades ago industrial centrifugal pump manufacturers quoted a single, relatively low value for minimum flow intended to prevent users...

Diffuser versus volute
The stator section of a centrifugal pump, after flow exits the impeller, is usually either a ‘diffuser’ or a ‘volute’. The purpose of each of these two stator types is...
