Bell & Gossett 179253LF E9004S 1.25AAB Series 90 Pump

Support 1-1/4-inch hydronic zoning with Bell & Gossett 179253LF E9004S, a 1/4 HP Series e-90 pump for high-efficiency boiler systems. Its single-phase motor accepts 115 or 208–230 V power, making it suitable for compatible commercial and institutional service panels. The 1.25AAB flanged configuration fits defined piping layouts, but confirm connection spacing, pump curve, and installation orientation before replacing an existing circulator.

The pump uses a stainless-steel shaft sleeve and maintenance-free sealed ball bearings within the Series e-90 close-coupled in-line arrangement. Those features reduce routine lubrication work while keeping the rotating assembly aligned during normal hydronic operation. The supplied data does not state flow, head, pressure, amp draw, seal material, physical dimensions, or weight, so verify the manufacturer’s submittal and leave enough clearance for flange inspection and motor service.
