Correct impeller for JEP2.0 VS pump?

[cg11]

I have a Jandy model JEP2.0

I'm looking for the impeller but I'm confused by the schematics.

Inyopools lists 2 different parts for the impeller, one for 2.2 HP and one for 2.7 HP.

But mine is the 2.0 HP.

So which part number do I need for JEP2.0?

The "JEP 2.0" pump has a service factor of 1.35 so the THP for the pump is actually 2.7. Therefore, you need the 2.7 HP impeller.

The "JEP 1.5" pump has a service factor of 1.47 for a THP of 2.2. Confusing but this is why the impellers are listed the way they are.

Thanks! I don't fully understand the service factor thing but I guess it doesn't matter as long as I get the right part
