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 115 V single-phase configuration and 1-inch flanged size suit smaller commercial and institutional DHW loops where circulation demand changes throughout the day. Confirm the auto-sensing claim, control requirements, and system curve against the current manufacturer submittal before installation.

The ECM motor operates within the supplied 115/208–230 V range and drives a full-diameter 5.25-inch impeller in the All-Bronze assembly. Manufacturer reference data identifies Be650S-ECM as a 1-inch, 115 V, 1/2 HP model. Flow, head, amp draw, seal material, dimensions, and weight were not provided, so verify the exact configuration and connection details before startup.
