Bell & Gossett Series 1531 Model 2E Pump 7-1/2 HP 1750 RPM Motor

Description

District cooling uses Bell & Gossett 1531 Model 2E for higher-head pumping at low RPM in commercial HVAC loops. This 7.5 HP close-coupled pump operates at 1750 RPM with a 9.5-inch nominal impeller, 3-inch suction, and 2-inch discharge connection. Confirm the 175 PSI working-pressure rating, motor phase, suction conditions, and system curve before startup.

The Bell & Gossett Series e-1531 2E uses a close-coupled four-pole configuration with large-volute construction for district cooling service. Its 3 x 2 case arrangement supports the listed suction and discharge sizes, while verified data does not include voltage, amp draw, GPM, maximum head, seal material, operating temperature, dimensions, weight, thermal protection, or self-priming capability. Match the pump to the approved hydraulic curve and support connected piping independently.
