Bell & Gossett Series 80 Pump 4 x 4 x 7 With 1-1/2 HP 1750 RPM Motor

B&G Series 80 4x4x7 1.5HP

The Bell & Gossett Series 80 Model 4x4x7 is engineered for efficient low-head, high-volume circulation, utilizing a 7-inch impeller within a compact in-line volute. This mechanical configuration focuses on creating a smooth laminar flow path between the 4-inch suction and discharge ports, preventing the cavitation and turbulence that can occur in large-diameter piping. The rigid motor bracket ensures positive concentric alignment, protecting the pump casing from the structural fatigue associated with the vibration of high-flow commercial HVAC systems.

With a 1.5 HP 1750 RPM motor, this Series 80 model offers exceptional electrical efficiency for general service pumping. The motor insulation is rated for thermal stability up to 225°F, ensuring the internally flushed mechanical seal remains protected from radiant heat. By maintaining a steady torque-to-load ratio, the electrical drive reduces mechanical stress on the motor frame, which directly lowers maintenance costs and extends the operational lifespan of the internal bearing assemblies in standard commercial setups.
