Bell & Gossett 179322LF (Be9012S) e-90 Series 2" All-Bronze In-Line Centrifugal Pump
Engineered for high-efficiency fluid circulation and long-lasting corrosion resistance, the Bell & Gossett 179322LF (Model Be9012S) is a close-coupled in-line centrifugal pump designed for commercial HVAC hydronic heating, cooling, potable water, and boiler recirculation applications. Featuring a 2" flanged connection, a 1/2 HP ODP motor, and a 4.25" impeller, this All-Bronze unit delivers quiet, continuous performance across medium-capacity liquid circulation loops.
The e-90 series utilizes a close-coupled design built on a standard NEMA 56J motor platform, eliminating the need for a separate bearing frame, coupler, or stub shaft. Its back-pull-out construction allows internal servicing without disturbing system piping connections. Equipped with a 303 stainless steel shaft, double-sealed ball bearings, and a unitized EPR/Carbon/Silicon-Carbide mechanical seal, this pump ensures superior durability and leak-free operation up to 175 PSI.
Key System Performance Baselines:
- All-Bronze Construction: Cast bronze volute and impeller provide maximum corrosion resistance in potable water and open hydronic systems.
- Back-Pull-Out Design: Internal pump assembly and motor remove easily from the rear of the casing without disconnecting piping.
- Close-Coupled Efficiency: Compact footprint mounts directly into horizontal or vertical pipe lines with no external coupling alignment required.
- Durable Mechanical Seal: Factory-fitted with a unitized EPR/Carbon/Silicon-Carbide mechanical shaft seal rated up to 250°F.
⚠️ Application Profile: Ideal for commercial hydronic heating, chilled water cooling, potable hot water circulation, pressure boosting, and boiler recirculation lines requiring 2" flanged connections up to 175 PSI operating pressure.
