I have a pump that has a NPSH requirement of 2 m when it runs with water. I want to run condensate of a density of 700 kg/m3 and a viscosity of 0.53 cP. I recalculate the new NPSH available, but I wonder if the NPSH required stays the same?
Have an insight or suggestion?

Re: NPSH requirement2 July 2007 at 1:29pmTheoretically, the NPSH required should be the same regardless of the nature of the liquid. Having said it, you should check this with the pump supplier/manufacturer that will have all such information pertaining to your particular pump and service immediately available.
