For over 75 years, Lockwood Products has been designing high quality custom boiler feed systems while providing superior customer service at an economic price. The packaged atmospheric-pressure storage tank blends makeup water, condensate returns, and water treatment chemicals before being pumped to the steam boiler. Horizontal and vertical boiler feed systems can be fully customized to meet each customer’s specific needs.
Horizontal Boiler Feed Systems
Lockwood horizontal boiler feed systems are offered as a standard for all boiler applications in simplex, duplex, and triplex configurations. In a standard boiler feed system setup, the storage tank combines makeup water, condensate returns, and water treatment chemicals before pumping the now blended water to the steam boiler. The system’s packaged atmospheric pressure storage tanks are built for commercial and industrial steam systems. To provide enough NPSH for water temperatures up to 200°F, the storage tank is elevated over the feedwater pumps. Vertical multistage centrifugal feedwater pumps are recommended for most commercial and industrial applications, as they perform well for low-flow, high-pressure pumping applications. Makeup water controls can be a mechanical, float/probe type with solenoid valve or modulating with an electronic control valve, and steam preheat packages are available to elevate water temperature prior to sending makeup water to the boiler. All storage tanks come standard with reinforced tank connections and receivers constructed with heavy steel plating and two integrated vents. The tank itself is constructed of carbon steel but can be upgraded to stainless steel for increased system life and system pumps can be selected for either intermittent service or continuous as specified. In addition to these options, a thermometer with separable well, gauge glass, and pump suction piping with a shutoff valve and strainer are available.
Vertical Boiler Feed Systems
Lockwood vertical boiler feed systems provide capacities up to 750 BHP. In a standard boiler feed system setup, the storage tank combines makeup water, condensate returns, and water treatment chemicals before pumping the finished product to the steam boiler. To provide enough NPSH for water temperatures up to 200°F, the storage tank is elevated over the feedwater pumps. Vertical multistage centrifugal feedwater pumps are recommended for most commercial and industrial applications, as they perform well for low-flow, high-pressure pumping applications. Makeup water controls can be a mechanical, float/probe type with solenoid valve or modulating with an electronic control valve, and steam preheat packages are available to elevate water temperature prior to sending makeup water to the boiler. All storage tanks come standard with carbon steel but can be upgraded to stainless steel for increased system life. In addition to these options, control panels, isolation valves, check valves, pressure gauges, and thermometers are available as optional accessories.
Type BMX Boiler Feed Systems
Lockwood Type BMX boiler feed systems are close coupled centrifugal pumps supporting capacities up to 125 BHP and discharge pressures at up to 40 PSIG. The floor mounted receivers on this system support up to 209-gallons. The system includes a bronze internal makeup valve. Optional accessories to this product include control panels, isolation valves, pressure gauges, check valves, and thermometers.
Type VCM
Lockwood Type VCM boiler feed systems are centrifugal pumps attached to a heavy duty, welded, carbon steel receiver available in rectangular configurations with capacities ranging from 100 to 500 gallons.
