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

The ECM motor adjusts output within the XL 70-145 performance range, while the cast-iron body suits compatible closed-loop heating and cooling systems. Manufacturer reference data identifies the model as a 2 HP, 208–230 V single-phase pump with a 55 W to 1400 W power range. Verify amp draw, dimensions, weight, port reach, operating pressure, and service clearance against the current submittal before startup.
