how to obtain a centrfugal pump curve ???? and how can say from the sound of the pump if its running under cavitation or not ?? and whats the cavitation signs for the pump

Again, use the pump curve.

Cavitation usually results in a "gravel" sound coming from the pump (i.e. like there are rocks in the pump spinning around). Also, this usually results in unusual vibrations as well.
