how to read centrifugal pump curve|pump performance curve explained : dealer Aug 22, 2016 · How To Read a Centrifugal Pump Curve? A centrifugal pump curve has its highest point on the left and gradually slopes down to the right. As you can see in the … This column will focus on self-priming pumps which is an internal method. All Pumps Are Not Created Equal. I will address only centrifugal pumps in the self-priming category, but first I will make a few generic comments about positive displacement (PD) pumps. Essentially all positive displacement pumps are, in principle, self-priming by design.
