What does the NPSH ratio of a pump mean? How to choose the NPSH ratio for a pump?
Thank you for your suggestion. The definition is given in 610, but how do I choose or determine this value and where can I find it?
There is a formula for calculating the cavitation specific speed; it is necessary to ensure that the cavitation level of the pump does not drop too low, as this will result in hydraulic losses which are detrimental to the pump. Generally, this value should be less than 11,000

The NPSH ratio is related to the cavitation performance of the pump, and this should be something that pump design engineers take into consideration
