Bell & Gossett 90-3T Series 90 Centrifugal Pump 1HP

Run commercial HVAC water with Bell & Gossett 90-3T Series 90 centrifugal pump for high-efficiency three-phase boiler systems. Its 1 HP motor accepts 208–230 or 460 volts, while the NEMA 56J frame provides a defined motor-interface reference. The 175 psi maximum working pressure and 225°F operating-temperature limit help establish system boundaries. Confirm the pump curve, connections, phase rotation, and clearance before installation.

The 90-3T uses a Series 90 in-line centrifugal arrangement with a 1 HP three-phase motor and NEMA 56J frame. Its 208–230/460-volt configuration requires field verification before wiring, while the listed pressure and temperature limits guide connected-system review. The supplied specifications do not state flow, head, impeller diameter, seal construction, connection size, dimensions, or weight. Verify those details in the manufacturer’s technical documentation.
