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

when replacing an impeller are other parts usually required?

Hello Gary, we would recommend the PENTAIR SHAFT SEAL ASSEMBLY OEM (071734S).
