Bell & Gossett 179270LF E9021S 1AAB Series e90 Pump

Description

Commercial HVAC recirculation uses Bell & Gossett 179270LF E9021S for secondary systems requiring compact 1-inch flanged circulation. Its 1/3 HP single-phase motor accepts 115 or 208 to 230 V, while the Series e-90 high-efficiency configuration supports compatible commercial hydronic loops. Confirm the 225°F temperature limit, mechanical seal, flange alignment, and system curve before startup.

The E9021S uses a 1AAB pump size with a carbon, ceramic, and Buna-N mechanical seal. Its close commercial circulation format suits secondary HVAC systems, but verified data does not include GPM, maximum head, amp draw, RPM, impeller material, dimensions, weight, thermal protection, or self-priming capability. Match the pump to the operating point and maintain adequate fluid conditions before installation.
