{"product_id":"diffuser-1-1-2hp-3hp","title":"Sta-Rite Diffuser for 1-1\/2 HP to 3 HP Pumps","description":"\u003cp\u003eThe Sta-Rite C1-271P is the pump diffuser covering 1-1\/2 HP through 3 HP. One part number spans that whole range, which is worth knowing because the impeller behind it is horsepower specific and the diffuser is not.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat the diffuser does\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe impeller throws water outward at speed. The diffuser is the shaped housing that catches it and turns that speed into the pressure the filter and returns actually see. When it cracks, warps from heat, or loses the fit around the impeller hub, water recirculates inside the pump instead of leaving it. The symptom is a pump that sounds normal and moves noticeably less water.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003ePump coverage\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eC1-271P is carried in the parts groups for the Sta-Rite Max-E-Pro, the Sta-Rite IntelliPro VS 3050 and the Pentair Pinnacle, and it also appears in the Max-E-Glas II and Dura-Glas II listings.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhile the pump is open\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe o-ring that seals the diffuser and the diffuser screws are separate part numbers. Both are cheap, both are already exposed once the pump is apart, and neither is worth a second teardown.\u003c\/p\u003e","brand":"Sta-Rite","offers":[{"title":"Default Title","offer_id":48626120065236,"sku":"STA-101-8556","price":42.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_08c6bbdd-6c1c-4f4e-9bd7-3dc281c79bdb.gif?v=1788705101","url":"https:\/\/www.activepoolsupply.com\/products\/diffuser-1-1-2hp-3hp","provider":"Active Pool Supply","version":"1.0","type":"link"}
