Bell & Gossett Ecocirc XL N 20-35 104450LF is a high‑efficiency, stainless‑steel body circulating pump with an electronically commutated motor, designed for hydronic heating and cooling loops as well as potable‑water service. The N designation indicates a stainless steel pump body suitable for potable water pumping, and the 20–35 model name denotes a head range of 20–35 ft (about 6.1–10.7 m) at its rated operating point. It is a flanged, lead‑free unit with NPT connections in 1/2, 1, 1‑1/4, or 1‑1/2 in sizes, powered by a 115‑V, single‑phase 1/12‑HP ECM motor that draws roughly 6–85 W (0.1–1.3 A) depending on demand. The pump is rated for indoor use (IP44) with a maximum working pressure of 175 psi and supports a liquid temperature range from 14°F to 230°F, with domestic hot water installations typically recommended up to 149°F; overall dimensions are approximately 9.94 in long, 7.2 in wide, and 6.38 in high, making it suitable for tight mechanical rooms and closed‑loop systems.
