It is the genuine Pentair part, and it also appears in Pentair listings as 355270.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat the diffuser does\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe diffuser sits around the impeller and converts the velocity the impeller creates into pressure before the water leaves the volute. Its clearance to the impeller is what determines how much of the motor work actually reaches the plumbing, which is why the two parts are matched by horsepower and why a worn or cracked diffuser shows up as flow the pump should be making but is not.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eMatching the part\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThis one belongs on the high pressure, high head Challenger at 1-1\/2 HP full rated or 2 HP up rated. The impeller for that same rating is ordered separately, and on a rebuild it makes sense to fit both at once so the clearance between them is new.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":48625849204948,"sku":"PAC-101-3122","price":39.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_8ac4d055-70b9-42b7-aee3-7d45d558a56a.gif?v=1788701593","url":"https:\/\/www.activepoolsupply.com\/products\/diffuser-1-1-2hp-full-rated-2-hp-up-rated-high-pressure","provider":"Active Pool Supply","version":"1.0","type":"link"}
