Bell & Gossett 1.5AD Series e-1531 Pump 7.5HP Motor

B&G e-1531 Close Coupled Pump 7.5 HP

The Bell & Gossett e-1531 (1.5AD) is a high-velocity close-coupled vertical pump engineered to facilitate rapid fluid circulation in space-constrained commercial mechanical rooms. The close-coupled design integrates the 7.5 HP motor directly to the pump casing, neutralizing the need for a separate coupling and eliminating the risk of field misalignment. This mechanical configuration optimizes space utilization while the reinforced foot-mounted casing maintains structural stability, ensuring that the 1.5-inch discharge receives consistent volume delivery under sustained heavy-duty operational loads.

Powered by a robust 7.5 HP motor, this e-1531 configuration executes maximum torque delivery to maintain steady pressure in demanding hydronic applications. The internal mechanical seal is engineered to sustain vacuum-tight performance up to 250°F, protecting the motor core from moisture and heat-induced degradation. By leveraging precision-balanced components and heavy-duty motor bearings, this unit minimizes mechanical vibration and stabilizes rotational frequency, providing extreme reliability for primary or secondary commercial circulation service.
