That clearance is the only thing stopping discharge pressure from bleeding back into the suction side inside the pump. As the ring wears the gap opens, recirculation increases, and the pump moves less water for the same power. On a commercial installation that shows up as reduced turnover and a higher electricity bill long before anything makes a noise.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eThe horsepower reference\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eOur source lists the application as 7.5\/20HP CSPH\/CCSPH and does not say whether that describes a range or two ratings. We have carried it exactly as written rather than interpret it. Match part number 16830-0120 against your own pump before ordering, since our facts do not carry ring dimensions to check against.\u003c\/p\u003e","brand":"Sta-Rite","offers":[{"title":"Default Title","offer_id":48629121384660,"sku":"STA-101-1479","price":135.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_7b38b549-aa06-43fe-805d-28b3df79e27c.jpg?v=1788759884","url":"https:\/\/www.activepoolsupply.com\/products\/wear-ring-2","provider":"Active Pool Supply","version":"1.0","type":"link"}
