Bell & Gossett 1EF158LF Be650S-ECM AB Series e-60 Pump 1/2 HP

Adjust domestic hot-water circulation with Bell & Gossett 1EF158LF Be650S-ECM, a 1/2 HP all-bronze ECM pump for variable-speed potable-water service. Its single-phase motor accepts 115 V power, while the 1-inch flanged configuration suits smaller commercial and institutional loops. The supplied listing identifies auto-sensing voltage, but the manufacturer reference should be checked for the exact Be650S-ECM electrical configuration before purchase.

The ECM motor varies speed from approximately 350 to 1725 RPM within the Series e-60 assembly. The all-bronze body and full-diameter 5.25-inch impeller are identified in the supplied data, but flow, head, amp draw, seal material, dimensions, and weight were not provided. Confirm the 115 V supply, flange size, potable-water suitability, control settings, and system curve before installation.
