The Basics of Suction Specific Speed | Pumps Systems

Suction Specific SpeedMore Rules & FormulasBackgroundComments & Cautionary ResultsOver the last few years, I have witnessed a marked increase in the usage of NSS indices in request for quotation data sheets and pump engineering specifications crossing my desk. More often, the entity has little idea what NSS really means or the significance of the number. When I probe for how the end user or their engineer will use and evaluate the NSS data, I typically receive no answer and/or what I perceive as a misunderstanding. The intent of my query to the requesting party is to determine their assigned priority and weight of the NSS number in the overall pump evaluation process, especially when compared to other parameters such as efficiency, NPSH margin and proximity to best efficiency point (BEP). Note:Please realize there are plenty of people in the industry who fully understand the NSS concept and possess valid reasons for asking the question. This article is simply a refresher for those people. Let us revisit the NSS concept. It is not my intent to make this month’s ar...
