Boiler feed units for steam control
Ensure your boiler systems operate efficiently with a reliable water supply maintenance solution that integrates seamlessly with existing steam control processes, optimizing temperature control and preventing disruptions in your industrial heating operations.

The 4200 Series Boiler Feed Units from Sterlco® are designed to enhance the efficiency of your industrial heating and steam systems. These cast iron units effectively pump and maintain the water supply for boilers, crucial for HVAC systems, industrial processing, and power generation. The units feature atmospherically vented tanks, ranging from 6 to 120 gallons and can be paired with robust Sterlco® J & G centrifugal pumps. These pumps are engineered to handle hot condensate up to 200°F, equipped with durable cast iron housings and brass impellers for longevity.
Ideal for maintaining water supply and temperature control, the 4200 Series is crucial in industries like chemical processing and food and beverage. Their automatic operation integrates smoothly into existing systems, using energy-efficient 3450 RPM motors and offering customizable configurations. The units’ flexibility allows for simplex or duplex construction, optional electric alternators, and variety in motor types, making them adaptable to your specific operational needs. With heavy-duty components and optional features such as NEMA 12 Control Panels, these units promise low maintenance and high reliability essential for continuous industrial operations.
