Bell & Gossett 179252LF E9003S 1AAB Series 90 Pump

Keep compact commercial hydronics moving with Bell & Gossett 179252LF E9003S, a 1/2 HP Series e-90 pump for 1-inch flanged HVAC booster and circulation applications. Its single-phase motor accepts 115 or 208–230 V, while the bronze impeller and close-coupled arrangement suit compatible commercial piping. The 225°F maximum operating temperature gives installers a clear heating-system limit. Confirm the pump curve before installation.

The motor drives a 5-1/4-inch bronze impeller inside the 1AAB close-coupled in-line configuration. The supplied data does not state flow, head, pressure, amp draw, seal material, dimensions, or weight, so the pump should be matched to the actual system resistance rather than horsepower alone. Verify flange spacing, flooded suction, voltage, and air-purging requirements before startup.
