It is the genuine Sta-Rite part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat the diffuser does\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe diffuser sits over the impeller inside the pump housing. Water thrown off the impeller has speed but little pressure until the diffuser channels it, and that conversion is what gives the pump its head. It also seals the high pressure side of the impeller from the suction side.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen to change it\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA diffuser that has cracked, worn open at the impeller eye, or lost its seat lets water loop back inside the pump. The pump sounds fine but moves noticeably less water. Because the pump has to come apart to reach the diffuser, check the shaft seal and gaskets at the same time.\u003c\/p\u003e","brand":"Sta-Rite","offers":[{"title":"Default Title","offer_id":48634471383252,"sku":"STA-101-7161","price":46.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_c5c05cf5-42a3-4a16-90b4-72ccb1feec90.jpg?v=1788831684","url":"https:\/\/www.activepoolsupply.com\/products\/diffuser-ck-pump","provider":"Active Pool Supply","version":"1.0","type":"link"}
