It is matched to the motor rating, which is why a 2 HP impeller goes on a 2 HP pump and not on any other. Sand and grit that slips past the strainer basket wears the vanes down over the years, and debris can pack the passages solid.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen to change it\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eIf the pump primes, runs and sounds normal but flow is down, and you have already cleared the basket and ruled out a suction side leak, the impeller is the next thing to inspect. Order it by part number, since impellers for different ratings are hard to tell apart by eye.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":48633780830420,"sku":"PUR-101-0124","price":122.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_f168c558-55d9-42a2-b5e4-711916969e94.jpg?v=1788816157","url":"https:\/\/www.activepoolsupply.com\/products\/whisperflo-xf-2hp-impeller","provider":"Active Pool Supply","version":"1.0","type":"link"}
