I see a 2 hp and a 3 hp. Is there not a 2.5 hp impeller for the Whisperflo?

Hello Michael. Pentair Pool Products impellers are matched to Whisperflo pump models per the manufacture's specifications. Attached please find an exploded parts diagram of the Whisperflo Pump Series for reference. As you can see, the impellers are matched to multiple pump models with slight deviations in horsepower between them. The impeller, part number 073129, could be described as the closest match to the label 2.5 HP. Pentair / Purex Whisperflo WF, WFE, and WFDS Series

Had a pump motor failure. I replaced the motor and pump seals, but opted to wait on the impeller judging it looked fine. All the parts came in, replaced everything but the impeller. Within 2 hours the impeller failed. So, I bought this replacement. The old one had 5 years service on it running daily for 4 hours in our warm winters, and 8 hours a day in our hot summers. The replacement works fine and the pump and motor are running fine.
