NPSH Curve
NPSH Curve
(OP)
I want to test the pump and plot the NPSH curve.
Please advice how to go about the process. I have no idea as what to measure and how to go about the process

2) set ctiteria for cavitation (is it incipient, such as formation of first bubble - to be detected visually or by stroboscope, or you will detect loss of power or head drop as a sign of developed cavitation)
never done this, but seens to me like a serious task; try consulting books and standards

We found that lots of manufacturers either didn't do it accurately or maybe they cheated. It mattered with our type of equipment. We also found out who had it right and whose curves could be trusted.
I recently spouted off in a meeting at a clients office regarding this topic and called the names of several trusted pump companies (Carver pump among them) based on our test results, and they then introduced me to someone in the meeting who I hadn't previously met and who turned out to be the local Representative of Carver Pump. He was naturally beaming at my recommendation of his pump.
