Bell & Gossett B603S Series 60 Centrifugal Pump 1/2HP

Circulate potable water with Bell & Gossett B603S Series 60 centrifugal pump for high-flow domestic hot-water systems. Its 1/2 HP single-phase configuration uses an all-bronze lead-free body, a 1-1/2-inch by 1-1/2-inch by 5-1/4-inch arrangement, and an ODP motor. NSF-372 and Safe Drinking Water Act references support the supplied application. Confirm voltage and curve before installation.

The B603S uses an all-bronze body with a single-phase motor in the supplied Series 60 configuration. Its pump size identifies the 1-1/2-inch piping arrangement, while the supplied specifications do not state voltage, flow, head, RPM, seal materials, dimensions, weight, pressure, or temperature. Verify the nameplate, compliance documents, and manufacturer’s current submittal before ordering.
