Bell & Gossett Series 1531 Model 2BC Pump 3 HP 1750 RPM Motor

Description

Move low-flow circulation through quiet mechanical rooms with Bell & Gossett Series 1531 2BC, a 3 HP close-coupled pump listed for 1750 RPM three-phase operation. Its 2-1/2-inch suction and 2-inch discharge connections suit process water and secondary HVAC systems where the installer needs defined large-port geometry. Confirm the electrical data, impeller trim, suction conditions, and system curve before installation.

The four-pole motor drives a precision-trimmed impeller through the 2BC close-coupled assembly. The stainless-steel shaft sleeve provides the listed rotating-component detail, but flow, head, pressure, voltage, amp draw, dimensions, weight, and final impeller diameter were not supplied. Match the pump to the required operating point and provide proper pipe support and service clearance.
