The \u003cstrong\u003e110116MF-202\u003c\/strong\u003e model, part of the Armstrong H‑41 LV series, features a less‑volute design that minimizes turbulence and extends motor life.\u003c\/p\u003e\n\u003cp\u003eThe pump utilizes a centrifugal impeller housed in a reduced‑volume volute, allowing water to accelerate through the impeller and exit at a steady pressure. The streamlined flow path reduces cavitation risk and improves overall hydraulic efficiency.\u003c\/p\u003e\n\u003ch4\u003eKey System Performance Baselines:\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlow Capacity:\u003c\/strong\u003e Up to 30 GPM at 75 psi for reliable heat distribution.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePower Consumption:\u003c\/strong\u003e Approximately 115 W, supporting energy‑efficient operation.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNoise Level:\u003c\/strong\u003e Operates below 45 dBA, providing a quiet residential environment.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Compatibility:\u003c\/strong\u003e Rated for 120 V single‑phase power.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e⚠️ \u003cstrong\u003eApplication Profile:\u003c\/strong\u003e Ideal for residential boiler circulators, small‑scale commercial HVAC, and retrofits of existing low‑voltage hydronic loops.\u003c\/p\u003e","brand":"Armstrong","offers":[{"title":"Default Title","offer_id":43123655245918,"sku":"110116MF-202","price":1453.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0663\/7151\/8558\/files\/110116MF_202_image_b97f9ff6-9148-439d-b85b-67497027ad77.png?v=1786017312","url":"https:\/\/nationalboilersupply.com\/products\/armstrong-110116mf-202-h-41-lv-pump-less-volute","provider":"National Boiler Supply","version":"1.0","type":"link"}
