Replacing the **08-999-049-011** wear ring on the **Series eHSC** pump restores optimal seal performance and prevents overheating.\u003c\/p\u003e\u003cp\u003eThe wear ring forms a tight clearance with the impeller hub, directing the pump’s internal flow to sweep away heat and particles. This self‑flushing action eliminates the need for external flush lines, keeping the seal cool and free of contaminants.\u003c\/p\u003e\u003ch4\u003eKey System Performance Baselines:\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeal Life Extension:\u003c\/strong\u003e Proper wear‑ring geometry ensures consistent seal cooling and lubrication.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeat Management:\u003c\/strong\u003e Maintains optimal pump temperature by facilitating fluid flushing.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDebris Clearance:\u003c\/strong\u003e Provides a reliable path for particles to exit, protecting the seal.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReliability Boost:\u003c\/strong\u003e Reduces risk of seal failure caused by clogging or overheating.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e⚠️ \u003cstrong\u003eApplication Profile:\u003c\/strong\u003e Ideal for HVAC water‑to‑water chillers, commercial boiler feed‑water loops, and industrial cooling‑tower recirculation systems requiring continuous seal protection.\u003c\/p\u003e","brand":"Bell \u0026 Gossett","offers":[{"title":"Default Title","offer_id":43112698937438,"sku":"08-999-049-011","price":2968.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0663\/7151\/8558\/files\/08_999_049_011_image_e3ac5667-c2d7-4e43-be89-f9000dd85173.jpg?v=1785946696","url":"https:\/\/nationalboilersupply.com\/products\/bell-gossett-08-999-049-011-series-ehsc-impeller-wear-ring","provider":"National Boiler Supply","version":"1.0","type":"link"}
