Bell & Gossett 90-37S Series 90 Centrifugal Pump 1HP

Build high-head building circulation with Bell & Gossett 90-37S Series 90 centrifugal pump for single-phase multi-story HVAC systems. Its 1 HP motor accepts 115 or 208–230 volts, while the 2-inch AA flange and 7-inch bronze impeller define the supplied hydraulic arrangement. The 175 psi maximum working pressure provides a clear system limit. Confirm the pump curve, flange pattern, voltage, and clearance before installation.

The 90-37S uses a 7-inch bronze high-head impeller in a Series 90 in-line centrifugal assembly. Its single-phase motor accepts 115 or 208–230 volts, and the 2-inch AA designation identifies the flanged piping interface. The supplied specifications do not state flow, head, RPM, seal construction, bearing design, dimensions, or weight. Verify those details against the manufacturer’s documentation before ordering.
