Upgrading of Pumps

Very often when upgrading of pump to higher capacity .the piping system is not taken into consideration . Higher capacity for the same piping diameter would mean greater system pressure
If the piping length is very long . the system pressure should be recalculated to determine the new pumping head before selecting the pump .Suction line,the NPSH avialable must also be looked into

Otherwise .the new pump is not likely to perform as rated
