In 2012, the manufacturer changed the way Aquaflo pumps are rated. These pumps are now assigned both an operational horsepower (ohp), and a total horsepower (thp) rating. Previous versions of these pumps used only the operational horsepower. If you are replacing an older Aquaflo pump, be sure to match the operational hp rating rather than the total hp.
