Bell & Gossett 179278LF E9031S 1.5AAB Series e90 Pump

Confirm large-loop compatibility with Bell & Gossett 179278LF E9031S, a Series e-90 pump listed for 1-1/2-inch flanged commercial HVAC circulation. The supplied listing identifies a 1 HP single-phase motor, but manufacturer reference data associates E9031S with different motor information. Resolve the horsepower and impeller details against the pump nameplate before ordering, then compare the verified unit with the actual system curve.

The supplied data identifies 115 or 208–230 V single-phase power, a 1.5AAB flanged configuration, stainless-steel shaft sleeve, and carbon, ceramic, and Buna-N mechanical seal. Flow, head, pressure, amp draw, dimensions, weight, and final motor data were not confirmed. Check the current submittal, flange spacing, suction conditions, and electrical requirements before installation.
