Bell & Gossett 179006LF 90-4S 1-1/2 HP Motor

Large residential HVAC uses Bell & Gossett 179006LF Series 90 90-4S for high-flow hydronic boosting and building circulation. Its 1-1/2 HP single-phase motor accepts 115 or 208 to 230 V, while the cast iron bronze-fitted body, ODP motor, and sealed ball bearings support compatible HVAC loops. Confirm the system curve, 2-inch connection, motor voltage, and suction conditions before startup.

The Series 90 90-4S uses a close-coupled in-line centrifugal configuration with cast iron bronze-fitted construction. Its maintenance-free sealed ball bearings reduce lubrication requirements, while the ODP enclosure requires a dry, ventilated installation area. Verified data does not include GPM, maximum head, amp draw, RPM, seal material, operating temperature, dimensions, weight, thermal protection, or self-priming capability, so follow the approved pump documentation.
