Drive primary boiler circulation with Bell & Gossett 90-11T Series 90 centrifugal pump for high-volume three-phase hydronic systems. Its 1-1/2 HP motor operates at 208–230 or 460 volts, while the 3-inch flanged connection and 5-1/4-inch bronze impeller suit larger commercial piping. The stainless steel shaft sleeve provides an additional service detail for replacement comparison. Confirm the system curve, flange pattern, electrical supply, and lifting access before installation.

The 90-11T uses a 5-1/4-inch bronze impeller in a Series 90 in-line centrifugal assembly, driven by a 1-1/2 HP three-phase motor. Its 3-inch flanged connection identifies the piping interface, while the stainless steel shaft sleeve provides a specified wear-surface component for inspection. The motor accepts 208–230 or 460 volts, requiring phase and voltage verification. The supplied specifications do not state flow, head, RPM, seal materials, dimensions, weight, or pressure.

- Value: Matching the existing piping and electrical service can reduce retrofit work and boiler-room downtime.
- Audience: Fits boiler technicians, commercial HVAC contractors, central-plant engineers, and industrial maintenance buyers.

Applications & Use Cases

Use this pump in high-volume three-phase hydronics and primary boiler loops that match its electrical and hydraulic requirements. Check the 3-inch flange dimensions, gasket fit, pipe supports, valve clearance, shaft centerline, and lifting path before installation. The supplied data does not include overall dimensions, weight, flow, head, or pressure, so verify the manufacturer’s submittal before purchase.

Warranty & Support

- Warranty Terms: Warranty duration, coverage, exclusions, and registration requirements require confirmation from the authorized seller.
- Service Requirements: Confirm whether authorized service is required for warranty claims before purchase.
- Model Verification: Match Bell & Gossett 90-11T and SKU 179018LF to the seller’s order documentation.

Verify phase and voltage, align the flanges, support the connected piping, purge air, inspect strainers, and check the shaft sleeve during service. Select the operating point from the actual boiler-loop curve because flow and head are not supplied here.
