I have a 1 1/2 hp Pentair Challenger Pump. The motor is spinning. The "fan" impeller is not. I took it apart yesterday. Everything looks ok but it looks like the shaft is not making contact with the impeller assembly. I looked at parts on your site and hep videos. Everything I see shows a straight shaft where you put a screw in the end to hold the assembly in place. The shaft on my pump doe not look like this. It is tapered with threads on the outside.

please help me find the correct Spring seal and ceramic seal to go with this set up.

The heavy-duty shaft seal for the Pentair Challenger pump is part number 5250-210. Click Here to View the 5250-210 Shaft Seal

The other item you were describing is an impeller lock screw. That item is not absolutely necessary. Check out our article titled "Do I Need an Impeller Lock Screw?".
