The casting is gray iron and shows the typical as-cast finish with a machined bore hub featuring a keyway and bolt-circle flange for positive torque transmission on the pump shaft. Worthington (a Dresser Industries \/ FLOWSERVE lineage brand) and its Thelco product line were widely used in industrial centrifugal pumps across HVAC, water supply, and general industrial service; part number 953543 is associated with that pump family and requires a final OD trim to 9-5\/16 inches on a lathe prior to installation to match the specific pump casing clearance.\u003ctable style=\"width:100%;border-collapse:collapse;margin-top:16px;\"\u003e\n\u003ctr style=\"background:#56555b;\"\u003e\u003cth style=\"text-align:left;padding:8px 12px;color:#fff;font-size:13px;\" colspan=\"2\"\u003eProduct Specifications\u003c\/th\u003e\u003c\/tr\u003e\n\u003ctr style=\"background:#f5f5f5;\"\u003e\n\u003ctd style=\"padding:6px 12px;font-size:13px;font-weight:600;color:#333;border-bottom:1px solid #eee;width:40%;\"\u003eBrand\u003c\/td\u003e\n\u003ctd style=\"padding:6px 12px;font-size:13px;color:#555;border-bottom:1px solid #eee;\"\u003eThelco Worthington\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#ffffff;\"\u003e\n\u003ctd style=\"padding:6px 12px;font-size:13px;font-weight:600;color:#333;border-bottom:1px solid #eee;width:40%;\"\u003eMPN\u003c\/td\u003e\n\u003ctd style=\"padding:6px 12px;font-size:13px;color:#555;border-bottom:1px solid #eee;\"\u003e953543\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f5f5f5;\"\u003e\n\u003ctd style=\"padding:6px 12px;font-size:13px;font-weight:600;color:#333;border-bottom:1px solid #eee;width:40%;\"\u003eImpeller Type\u003c\/td\u003e\n\u003ctd style=\"padding:6px 12px;font-size:13px;color:#555;border-bottom:1px solid #eee;\"\u003eClosed (shrouded), centrifugal\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#ffffff;\"\u003e\n\u003ctd style=\"padding:6px 12px;font-size:13px;font-weight:600;color:#333;border-bottom:1px solid #eee;width:40%;\"\u003eAs-Supplied OD (Untrimmed)\u003c\/td\u003e\n\u003ctd style=\"padding:6px 12px;font-size:13px;color:#555;border-bottom:1px solid #eee;\"\u003e~10 in (untrimmed, as cast)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f5f5f5;\"\u003e\n\u003ctd style=\"padding:6px 12px;font-size:13px;font-weight:600;color:#333;border-bottom:1px solid #eee;width:40%;\"\u003eRequired Trim OD\u003c\/td\u003e\n\u003ctd style=\"padding:6px 12px;font-size:13px;color:#555;border-bottom:1px solid #eee;\"\u003e9-5\/16 in (per handwritten note on casting)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#ffffff;\"\u003e\n\u003ctd style=\"padding:6px 12px;font-size:13px;font-weight:600;color:#333;border-bottom:1px solid #eee;width:40%;\"\u003eMaterial\u003c\/td\u003e\n\u003ctd style=\"padding:6px 12px;font-size:13px;color:#555;border-bottom:1px solid #eee;\"\u003eGray cast iron\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f5f5f5;\"\u003e\n\u003ctd style=\"padding:6px 12px;font-size:13px;font-weight:600;color:#333;border-bottom:1px solid #eee;width:40%;\"\u003eHub Bore Feature\u003c\/td\u003e\n\u003ctd style=\"padding:6px 12px;font-size:13px;color:#555;border-bottom:1px solid #eee;\"\u003eKeyed bore w\/ bolt-circle flange\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"HereComesDataBoi","offers":[{"title":"Default Title","offer_id":67707795734743,"sku":"4553t108B","price":173.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0736\/0626\/7095\/files\/thelco-worthington-953543-centrifugal-pump-impeller-1.jpg?v=1791391721","url":"https:\/\/dansdiscounttools.com\/products\/thelco-worthington-953543-untrimmed-cast-iron-centrifugal-pump-impeller","provider":"Dan's Discount Tools","version":"1.0","type":"link"}
