using CFX to calculate NPSHR for pump

I am trying to calculate the NPSHR for a centrifugal pump. I do not have the specific feature to simulate cavitation. But I think I still could just get NPSHR. I can just run the flow field at different flow rates. And get the pressure drop between the pump inlet and the minumum pressure in the pump for each flow rate. The pressure drop will be the NPSHR for various flow rates. Theoretically, I think this is correct. Am I right? Thanks.
