Designed specifically for the 1600 series in-line pumps, this replacement component ensures precise flow rates and consistent system pressure by restoring the pump's internal geometry. The \u003cstrong\u003e1611-001SRP\u003c\/strong\u003e impeller assembly is built to withstand high system temperatures, preventing the cavitation and energy loss often associated with worn or degraded pump internals.\u003c\/p\u003e\u003cp\u003eThis impeller operates within the 1600 series pump housing to move fluid effectively while minimizing turbulence. When paired with the signature cool-bearing cartridge design, this stainless steel assembly helps protect the pump’s rotating elements from thermal stress. By maintaining a tight clearance between the impeller and the volute, it ensures the pump performs to its original manufacturer specifications, thereby extending the total service life of your circulator setup.\u003c\/p\u003e\u003ch4\u003eKey System Performance Baselines:\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurable Construction:\u003c\/strong\u003e High-grade stainless steel build provides superior resistance to corrosion and erosion in closed-loop systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOptimized Flow:\u003c\/strong\u003e Precision-engineered for 4.0\" to 4.75\" diameter applications to ensure calibrated hydraulic output.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnergy Efficiency:\u003c\/strong\u003e Restores pump performance to factory levels, reducing the electrical load required to overcome friction and fluid resistance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThermal Reliability:\u003c\/strong\u003e Engineered to integrate seamlessly with the 1600 series cool-bearing cartridge to mitigate heat transfer to critical motor components.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e⚠️ \u003cstrong\u003eApplication Profile:\u003c\/strong\u003e Ideal for commercial and residential hydronic heating, chilled water cooling, and domestic water recirculation systems utilizing Taco 1600 Series In-Line Pumps.\u003c\/p\u003e","brand":"Taco","offers":[{"title":"Default Title","offer_id":43125856305246,"sku":"1611-001SRP","price":417.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0663\/7151\/8558\/files\/1611_001SRP_image_26489640-91ca-4775-9053-659a32b67c5a.png?v=1786040946","url":"https:\/\/nationalboilersupply.com\/products\/taco-1611-001srp-stainless-steel-impeller-assembly-4-0-4-75","provider":"National Boiler Supply","version":"1.0","type":"link"}
