In my last column ("Tips for Proper Pump Selection," Pumps & Systems, May 2016, read it here), I briefly mentioned "drooping pump curves" and stated that I would spend time in a future article discussing the subject.A drooping pump curve is a characteristic head-flow pump performance curve that does not continually rise when moving from the best efficiency .
The dimensionless specific speed of a centrifugal pump, also known as the Suction Specific Speed (N ss), is a crucial parameter used in the selection and design of centrifugal pumps. It is a dimensionless number that helps determine the type of pump geometry - radial, mixed flow, or axial - to select for a stable and reliable operation with maximum efficiency and without cavitation.
The specific speed (n s) is a characteristic coefficient derived from the similarity conditions which allows a comparison of impellers of various pump sizes even when their operating data differ
