{"product_id":"diffuser-1-2-hp-thru-1hp","title":"Pentair SuperFlo Diffuser, 1\/2 HP Thru 1 HP","description":"\u003cp\u003eThe Pentair 355617Z is the diffuser for SuperFlo and SuperMax pool and spa inground pumps and the Pinnacle High Flow inground pump, in the smaller horsepower range. It is the genuine Pentair part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat a diffuser does\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe diffuser sits over the impeller and shapes the water leaving it, converting the speed the impeller creates into usable pressure as the flow enters the volute. When the diffuser cracks or its sealing face wears, water recirculates inside the wet end instead of going out to the filter, and the pump loses performance without any obvious noise.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eMatch your pump rating\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThis part covers the smaller end of the range. The listing title gives 1\/2 HP through 1 HP, and the detail line reads 1\/2 HP full rated through 3\/4 HP full rated plus the 1 HP up rated pump. Check the motor plate against both. Pumps rated above this range take the separate 1-1\/2 HP through 2 HP diffuser.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDo the small parts too\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe diffuser o-ring and the hex head screw that holds the diffuser in place are separate items. Both are cheap, both are already exposed once the wet end is open, and a hardened o-ring will leak past a brand new diffuser.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":48634020495572,"sku":"PAC-101-7227","price":91.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_324bcc34-2c25-4335-bb87-1c41a7e91cee.jpg?v=1788824813","url":"https:\/\/www.activepoolsupply.com\/products\/diffuser-1-2-hp-thru-1hp","provider":"Active Pool Supply","version":"1.0","type":"link"}
