NPSH Margin — how much?
A word on the terminology: Net Positive Suction Head (NPSH) is the sum of the total static plus kinetic pressure minus the liquid vapor pressure, at
Common Centrifugal Pump Terms in Plain English
The terminology of a technical subject is key to understanding it. The language of modern pump technology has evolved for well over a hundred years.
Is there any confusion about NPSH?
Net Positive Suction Head (NPSH) is perhaps the most misunderstood concept in pumping technology. The main source of confusion stems from multiple
