As a critical replacement component for Bell \u0026amp; Gossett pumping equipment, this 7-inch impeller ensures your system maintains consistent pressure and flow rates, effectively minimizing cavitation risks and excessive motor wear. By installing the \u003cstrong\u003eBell \u0026amp; Gossett P85520\u003c\/strong\u003e, you restore factory-spec performance to your circulation pump, ensuring longevity across your heating or cooling infrastructure.\u003c\/p\u003e\u003cp\u003eThe impeller functions as the rotating heart of the centrifugal pump, converting rotational energy from the motor shaft into kinetic energy to propel fluid through the pipe network. The 1-1\/4\" bore diameter provides a secure, precision fit onto the shaft, while the durable bronze construction offers superior resistance against corrosion and debris-related erosion common in closed-loop hydronic applications.\u003c\/p\u003e\u003ch4\u003eKey System Performance Baselines:\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Composition:\u003c\/strong\u003e High-grade bronze for enhanced corrosion resistance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrecise Geometry:\u003c\/strong\u003e 7-inch diameter designed for optimal fluid displacement.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShaft Compatibility:\u003c\/strong\u003e Engineered with a 1-1\/4\" bore for stable, vibration-free operation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReliability:\u003c\/strong\u003e Genuine OEM construction ensures seamless integration with existing housing.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e⚠️ \u003cstrong\u003eApplication Profile:\u003c\/strong\u003e Suitable for commercial and residential hydronic heating systems, chilled water loops, and light industrial fluid transfer systems requiring reliable, steady-state circulation.\u003c\/p\u003e","brand":"Bell \u0026 Gossett","offers":[{"title":"Default Title","offer_id":43136919535710,"sku":"P85520","price":1169.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0663\/7151\/8558\/files\/P85520_image_5f0e38c9-aecc-478d-999b-d9e9d36a260c.png?v=1786155557","url":"https:\/\/nationalboilersupply.com\/products\/bell-gossett-p85520-bronze-7-impeller-with-1-1-4-bore","provider":"National Boiler Supply","version":"1.0","type":"link"}
