A cracked or worn diffuser reduces hydraulic efficiency and can cause the pump to lose prime or deliver reduced flow. Match the part number stamped on your existing diffuser before ordering to confirm the correct HP rating for your SuperFlo.\u003c\/p\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse; margin: 20px 0; border: 1px solid #ccc;\"\u003e\n\u003ctr style=\"background-color: #f8f9fa;\"\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003ePentair Part Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e355617Z\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003eCompatible HP Ratings\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e1\/2 HP Full Rated; 3\/4 HP Full Rated; 1 HP Up Rated\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #f8f9fa;\"\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003eQuantity Included\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003eEach\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003ePro Tip\u003c\/h3\u003e\n\u003cp\u003eSuperFlo diffusers are HP-specific — the 1\/2 HP Full Rated and 1 HP Up Rated diffusers are not interchangeable with the 1 HP Full Rated version. Before ordering, confirm the HP rating and service factor stamped on your pump's motor nameplate matches the ratings listed above. When the pump is open for diffuser replacement, inspect the impeller and shaft seal at the same time — replacing worn components together avoids a second disassembly.\u003c\/p\u003e\n\n\u003c!-- wft:processed:manual:2026-04-06 --\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":53960113291539,"sku":"355617Z","price":96.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/0687\/5411\/files\/pentair-diffuser-superflo-pump-355617z-2.webp?v=1778794002","url":"https:\/\/poolaroo.com\/products\/pentairwaterpoolandspainc_355617z","provider":"Poolaroo","version":"1.0","type":"link"}
