It is the part that seats over the impeller inside the pump body.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat it does\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe impeller throws water outward; the diffuser collects that flow and directs it into the volute so it leaves the pump as pressure instead of turbulence. A diffuser that has cracked, or whose center opening has worn open around the impeller nose, lets water recirculate inside the housing. The symptom is weak return flow that does not improve after you clean the pump basket and the filter.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eConfirm the horsepower\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe source information for this part is not consistent on horsepower. The listing title covers 1\/2 HP through 1-1\/2 HP, while the manufacturer description names 3\/4 HP and 1 HP. Compare the diffuser you have taken out against the photographs, and check the horsepower on the motor label, before you order.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhile the pump is open\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe diffuser O-ring is a separate part and is the seal between the diffuser and the volute. Since the pump has to come apart either way, it makes sense to fit a new O-ring, and to look over the impeller and shaft seal at the same time.\u003c\/p\u003e","brand":"Sta-Rite","offers":[{"title":"Default Title","offer_id":48627878559956,"sku":"STA-101-2805","price":42.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_6abe12ce-eee2-4165-a3f3-51aecf5580e9.gif?v=1788729529","url":"https:\/\/www.activepoolsupply.com\/products\/diffuser-1-2hp-1-1-2hp","provider":"Active Pool Supply","version":"1.0","type":"link"}
