Move high-head commercial water with Bell & Gossett 172749LF 613T, a Series 60 three-phase circulator for secondary HVAC and hydronic heating. Its 208–230/460 V motor and 1-1/2-inch by 1-1/2-inch by 6-1/4-inch configuration suit larger commercial loops. The supplied listing identifies a 6-1/4-inch impeller, while Series 60 reference data associates the 613T with a different impeller diameter, so verify the trim before purchase.

The 3/4 HP maintenance-free pump uses sealed ball bearings within the Series 60 assembly. The supplied data does not state flow, head, pressure, amp draw, seal material, dimensions, weight, or final impeller diameter. Confirm the current submittal, flange spacing, phase rotation, flooded suction, and system curve before installation.
