Bell & Gossett 90-11T Series 90 Centrifugal Pump 1-1/2HP

B&G 179018LF Series 90 Model 90-11T 1-1/2 HP Pump

The Bell & Gossett 179018LF (Series 90, Model 90-11T) is a high-capacity Lead-Free (LF) close-coupled centrifugal pump engineered to facilitate massive fluid distribution in expansive commercial architectures. Its robust in-line volute is calibrated to stabilize high-velocity flow while neutralizing the hydraulic noise common in 1-1/2 HP systems. By prioritizing a lead-free internal architecture, this unit facilitates rapid thermal circulation and maintains structural stability, ensuring that large-scale district potable water and heating systems receive reliable pressure delivery without the maintenance requirements of traditional coupled pumps.

Driven by a high-torque 1-1/2 HP Three-Phase (T) motor, the 179018LF executes superior rotational stability and balanced electrical consumption across all phases. The close-coupled configuration eliminates the need for field alignment, utilizing a precision-ground shaft that connects directly to the non-ferrous impeller. By leveraging industrial-grade bearings and a specialized mechanical seal, this configuration minimizes mechanical stress and stabilizes rotational frequency, providing maximum uptime and reliability for continuous-duty commercial service.
