Designed specifically for Series HV and Series 2 pumps, this replacement component ensures your circulating system operates at the correct flow and head pressure. By replacing a worn or damaged impeller with part \u003cstrong\u003e118668\u003c\/strong\u003e, you restore factory-specified pump efficiency and prevent cavitation, vibration, and premature wear on the motor bearings.\u003c\/p\u003e\u003cp\u003eThis impeller functions by utilizing centrifugal force to move fluid from the pump inlet to the discharge, maintaining consistent pressure across the system architecture. As the motor rotates the shaft, the impeller blades translate mechanical energy into kinetic energy, pushing the heating or cooling medium through the plumbing network. Proper geometry of the impeller is critical for achieving the design curve of the pump, ensuring that energy consumption remains minimized during high-demand cycles.\u003c\/p\u003e\u003ch4\u003eKey System Performance Baselines:\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlow Optimization:\u003c\/strong\u003e Restores factory-rated GPM capacity to support efficient heat distribution.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHydraulic Balance:\u003c\/strong\u003e Precision-engineered design reduces turbulence and internal fluid friction.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Service Life:\u003c\/strong\u003e Constructed to withstand the mechanical stress of continuous duty cycling.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnergy Efficiency:\u003c\/strong\u003e Helps maintain system pump curves to minimize electrical draw on circulating motors.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e⚠️ \u003cstrong\u003eApplication Profile:\u003c\/strong\u003e Primarily utilized in commercial and industrial HVAC hydronic heating systems, chilled water loops, and liquid transfer applications where Series HV and Series 2 pump housings are currently installed.\u003c\/p\u003e","brand":"Bell \u0026 Gossett","offers":[{"title":"Default Title","offer_id":43136065568862,"sku":"118668","price":187.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0663\/7151\/8558\/files\/118668_image_68a5c36e-e1f7-4aa3-bda5-b7a624c40cab.png?v=1786124896","url":"https:\/\/nationalboilersupply.com\/products\/bell-gossett-118668-impeller-for-series-hv-and-series-2-pumps","provider":"National Boiler Supply","version":"1.0","type":"link"}
