Bell & Gossett 90-40T Series 90 Centrifugal Pump 1-1/2HP

B&G 179055LF Series 90 Model 90-40T 1-1/2 HP Pump

The Bell & Gossett 179055LF (Series 90, Model 90-40T) is a massive-capacity Lead-Free (LF) close-coupled centrifugal pump designed to facilitate maximum thermal distribution in expansive commercial infrastructures requiring 3-phase power. Its robust in-line volute is calibrated to stabilize high-velocity flow while neutralizing hydraulic noise in high-output systems. By prioritizing a lead-free internal architecture and a powerful 1-1/2 HP motor, this unit facilitates rapid fluid circulation and maintains structural stability, ensuring that large-scale district potable water and heating systems receive reliable pressure delivery without the maintenance requirements of coupled pumps.

Driven by a high-torque 1-1/2 HP Three-Phase (T) motor, the 179055LF 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 connecting directly to the 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 in demanding environments.
