Sterling 5000 Series Boiler Feed Units In Stock

Receivers are constructed from heavy 3/16" steel, available in 125–714 gallon sizes, with narrow tanks (up to 250 gallons) designed to fit standard doorways. Each unit features 3450 RPM close-coupled stainless shaft motors, a mechanical make-up water valve with stainless float (rated to 45 PSI, PRV required above), and bronze-fitted centrifugal pumps. Boiler-level controls manage pump operation, with automatic make-up when condensate is delayed. The “SterlSeal” ceramic seal runs on the bronze impeller hub, isolating the motor shaft from condensate and rated to 250°F. Isolation valves are standard, with pumps designed for a wide range of pressures and easy servicing.
