My last two columns (Pumps & Systems, April and May 2014) explained how pump suction behavior depends on how suction pressure is reduced. The original video, which showed two suction pressure tests,...
In the February 2010 issue of Pumps & Systems, I discussed my Suction Specific Speed (S) Calculator and its ability to predict the stable range of flow for a particular centrifugal pump. In November...
Q. What are some differences between specific speed and suction specific speed for a rotodynamic pump? A. The Hydraulic Institute defines specific speed as an index of pump performance (developed...
