Manage district-heating flow with Bell & Gossett 104315 ecocirc XL 70-145, a cast-iron ECM circulator for high-head, high-flow secondary loops. Its 208–230 V single-phase motor, 70 feet maximum head, and 145 GPM maximum flow suit commercial hydronic systems where demand changes across the day. The push-button interface and LED status indicators simplify basic field checks. Confirm the flange layout and control wiring before installation.

The ECM motor adjusts pump output within the XL 70-145 operating range, while the cast-iron body suits compatible closed-loop heating and cooling systems. The supplied data does not state amp draw, exact dimensions, weight, port-to-port reach, or pressure rating, so verify the current submittal and approved system curve before startup. Leave access around the controls and motor for commissioning and service.
