Bell & Gossett Be9001S Series e90 Bronze Inline Pump 1AAB

Bell & Gossett Be9001S Bronze

The Be9001S is constructed with a high-grade bronze volute and a 4.5-inch impeller to ensure corrosion resistance in potable water and boiler feed applications. The mechanical design focuses on maintaining laminar flow at a steady 1725 RPM, which prevents the erosive effects of turbulence on the bronze surfaces. This material integrity, combined with a precision-balanced impeller, eliminates the vibration that leads to cavitation and mechanical seal leakage, ensuring the pump maintains structural stability and pressure consistency throughout its service life.

Driven by a 0.25 HP single-phase motor, this unit provides efficient torque for low-head circulation tasks. The electrical system includes integrated thermal overload protection to prevent the motor from exceeding the 250°F threshold, which is vital for preserving the integrity of the EPR/Carbon/Silicon-Carbide mechanical seal. By maintaining a stable electrical cycle, the motor reduces heat generation, protecting the internal bearings from thermal breakdown and ensuring a long Mean Time Between Failure (MTBF) in open and closed-loop potable systems.
