Bell & Gossett 179009LF 90-6S Pump 3/4 HP Motor

Description

Commercial hydronic circulation uses Bell & Gossett 179009LF Series 90 90-6S for secondary zone control and compatible HVAC loops. Its 3/4 HP single-phase motor accepts 115 or 208 to 230 V, while the 2-inch flanged connection and 5-1/4-inch bronze impeller support commercial water circulation. Confirm the carbon, ceramic, and Buna-N seal compatibility, system curve, and suction conditions before startup.

The Series 90 90-6S uses a close-coupled high-head configuration with cast iron bronze-fitted construction. Its mechanical seal combines carbon, ceramic, and Buna-N materials, while the supplied data does not include GPM, maximum head, amp draw, RPM, operating temperature, dimensions, weight, thermal protection, or self-priming capability. Match the pump to the secondary-loop duty point and support connected piping independently.
