Hoffman 161052 Boiler Feed Duplex Pump 50HBFD-1520

Hoffman 161052 50HBFD-1520 Duplex

The Hoffman 161052 Model 50HBFD-1520 is a high-capacity duplex boiler feed unit designed for large-scale steam applications. This mechanical system features a 50-gallon heavy-gauge receiver and two independent centrifugal pumps. The duplex configuration provides 100% redundancy, ensuring the boiler never experiences a low-water condition if one pump requires service. The mechanical architecture is optimized for 1750 RPM, delivering 15 GPM at 20 PSI per pump, with a large-volume tank that allows for the thermal stabilization of return water before it is injected back into the boiler.

Equipped with two 1/3 HP motors, the 161052 utilizes a dual-float switch arrangement to manage the electrical load. This setup allows for lead-lag operation, where the second pump can be electrically activated if the boiler demand exceeds the capacity of the primary pump. Consistent electrical synchronization reduces mechanical stress across the drive assemblies, maximizing the MTBF for critical heating infrastructure in schools, hospitals, and industrial facilities.
