It is the genuine Pentair part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat the diffuser does\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe diffuser sits over the impeller in the wet end and converts the spinning flow leaving the impeller into steady pressure heading out of the pump. It is also what lets the pump hold prime. When it cracks, warps or wears at its sealing face, the pump becomes noisy, loses pressure and struggles to prime, and the impeller usually takes the blame.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eGetting the right one\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eXF diffusers are matched to horsepower. This is the 5 HP part, so check the rating on your motor plate before ordering. Since the wet end is already open when the diffuser is changed, it is a sensible time to look at the impeller and the seal as well.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":48625810571476,"sku":"PUR-101-0123","price":107.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_18d280d5-f88f-4f4d-bc95-42e24efbbf9b.jpg?v=1788700384","url":"https:\/\/www.activepoolsupply.com\/products\/whisperflo-xf-5hp-diffuser","provider":"Active Pool Supply","version":"1.0","type":"link"}
