Lev,

Thank you for you help, regarding pump upgrade. The capacity of the pump with the modified impeller went up at least by 17%.  We also saw a significant NPSH improvement, and efficiency increased by 3%. We have not had any failures of this pump since the impeller was modified.. As far as the performance curve is concerned, the range of flow that we can now reach is from 225 to 550 gpm.  Prior to modification of the impeller we could not get over 450gpm. The unit is very happy with the result, and we consider it a success.
