It is the genuine Pentair part, the same impeller the pump left the factory with.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat the impeller does\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eEverything the pump achieves comes down to the impeller. The motor turns it, and the vanes throw water outward to create the flow that feeds the filter, the heater and the returns. When those vanes wear down, crack or fill with grit, the motor keeps running at full speed while the water slows, which is why a pump can sound perfectly healthy and still fail to turn the pool over.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eMatch the horsepower\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eChallenger impellers are horsepower specific and this one is the 3 HP high pressure version. Read the rating on the motor plate before ordering, because an impeller from a different rating will not give the pump the performance it was designed for.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhile the wet end is open\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe mechanical seal sits directly behind the impeller, so the same teardown reaches it.
