Designed specifically for integration with H-41 series pumps, the \u003cstrong\u003e816301-325K\u003c\/strong\u003e ensures consistent fluid circulation while resisting corrosion. By replacing a worn or damaged impeller, you prevent cavitation and reduce motor strain, keeping your circulation loop operating at its peak potential.\u003c\/p\u003e\u003cp\u003eThe impeller functions by utilizing centrifugal force to accelerate the fluid from the pump suction to the discharge outlet. As the motor spins the shaft, the impeller blades generate the pressure differential required to move heat transfer fluids through your hydronic infrastructure. Its non-ferrous construction provides durability against typical mineral buildup and oxidation often found in closed-loop systems.\u003c\/p\u003e\u003ch4\u003eKey System Performance Baselines:\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Composition:\u003c\/strong\u003e Corrosion-resistant non-ferrous alloy for extended service life.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHydraulic Precision:\u003c\/strong\u003e 4.25\" diameter geometry optimized for H-41 pump housings.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation Efficiency:\u003c\/strong\u003e Direct-fit replacement allows for rapid maintenance and reduced system downtime.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e⚠️ \u003cstrong\u003eApplication Profile:\u003c\/strong\u003e Primarily utilized in commercial and residential hydronic heating loops, chilled water systems, and primary-secondary pumping configurations requiring H-41 model pump assemblies.\u003c\/p\u003e","brand":"Armstrong","offers":[{"title":"Default Title","offer_id":43133733666910,"sku":"816301-325K","price":244.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0663\/7151\/8558\/files\/816301_325K_image_ebc728cc-1a0a-4d31-a700-a22d2c8fea78.png?v=1786108812","url":"https:\/\/nationalboilersupply.com\/products\/armstrong-816301-325k-4-25-non-ferrous-impeller-for-h-41-pumps","provider":"National Boiler Supply","version":"1.0","type":"link"}
