It is the genuine Pentair part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat it does\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe diffuser sits over the impeller inside the pump housing. Water leaves the impeller vanes fast and turbulent, and the diffuser is what turns that speed into steady pressure before the flow reaches the volute and the discharge. When the diffuser cracks, wears at the impeller face or loses its seal, water recirculates instead of moving on, and the pump pushes less water for the same power.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eMatching it to your pump\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe listing describes the horsepower coverage two ways: .5 HP to 2 HP in the product name, and 1\/2, 3\/4 and 2-1\/2 HP in the detail. Both readings are carried here rather than picking one. Use the WFE model number stamped on the pump to confirm the fit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhile the pump is open\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eReaching the diffuser means opening the wet end, which is the same job as replacing the shaft seal and the housing gasket. Those are separate parts and are worth doing at the same time.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":48625747165396,"sku":"PUR-101-1058","price":76.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_58918dc4-2e0b-4fdb-bed9-76d4fccfbc4d.png?v=1788691341","url":"https:\/\/www.activepoolsupply.com\/products\/whisperflo-diffuser-5hp-2hp","provider":"Active Pool Supply","version":"1.0","type":"link"}
