Family Curves

Below are the family curves for nominal speed at 50Hz of supply frequency. Initial selection of the pump is to be done from these curves. If the required operating speed is different from the nominal speed, then the operating parameters should be converted to the nominal speed and then the selection is to be done.

The pump models shown in dotted lines are not yet developed in KSB India.
