Heres the rundown on the pump motor. The service factor of 1.65 means that it is constructed with more copper than a standard motor, so basically it will last forever. The bearings dont last for ever though. It is also a continuous duty motor (says so on the tag). The listed hp rating is the peak horsepower. The brake horsepower is 1.24hp due to the service factor. This means that the motor is really capable of supplying more power than advertised, which is why it is also rated for continuous duty.
The power draw is:
1512 Watts per hour at 120V
1386 Watts at 220V
I wasnt able to find a pump curve for that model, but using comparable models it will pump 3900-4400 gph.
The smaller pump's power draw is 480 Watts at 120V.
