Since there is no such a driver available, next highest HP rated motor is selected and that would be 10HP.Īs the result of the above process, you will have a 10HP pump with an actual load of 7.2HP or somewhere in that area. So the mechanical engineer has a choice to make and they usually size the pump dirver to the 'end of the curve' of the pump, in this case say 8.7HP. As applications match the standard equipment rating mechanically, it is likely that the selected pump can deliver more pressure/flow than the requirement. Let's say that the calculated horsepower requirements for a pump at the operating point is 7.2 HP. The actual load of course varies based on the torque requirements of each driven equipment. Full Load Amps is the nameplate rating of an equipment, it is the current it is expected to draw at rated load and rated voltage.
