Bell & Gossett 3AD Series e-1531 Pump 5HP Motor

Description

Secondary HVAC loops use Bell & Gossett 3AD Series e-1531 for commercial chilled-water circulation and compact close-coupled installation. Its 5 HP three-phase motor operates at 1750 RPM, while the 4 x 3 x 9.5 case, trimmed 7.5 to 8.25-inch impeller, and stainless steel shaft sleeve support compatible hydronic systems. Confirm the pump curve, phase rotation, suction conditions, and piping alignment before startup.

The Bell & Gossett e-1531 3AD uses a four-pole close-coupled configuration with a 4-inch suction, 3-inch discharge, and trimmed impeller. Its stainless steel shaft sleeve supports the rotating assembly, while verified data does not include voltage, amp draw, GPM, maximum head, seal material, operating temperature, dimensions, weight, thermal protection, or self-priming capability. Select the pump from the approved chilled-water curve and prevent suction-side air entry.
