That's with the motor producing 3HP for that entire time, which it wouldn't be. I agree, it probably makes more sense to buy a purpose built water pump assembly with a smaller motor but aside from a few internal inneficiencies a motor will only pull the power necessary to run the load. When a motor is rated for 3hp that means it can safely sustain a workload of 3hp without overheating or being physically damaged, not necessarily how much power it will draw.
