Armstrong 2011 inverted bucket steam trap is a flagship product in Armstrong International 2000 Series, designed for industrial steam systems and providing reliable condensate removal and steam retention. As an all-stainless-steel inverted bucket steam trap, it combines energy efficiency, easy installation, and long service life for heating, drying, and process control applications in high-pressure environments. For high-performance steam trap requirements, Armstrong 2011 is an ideal choice.

Product Specifications and Technical Parameters

Armstrong 2011 steam trap uses the inverted bucket principle, automatically opening and closing based on the density difference between condensate and steam. This ensures efficient drainage with minimal steam loss. Detailed specifications are listed below:

• Model: 2011 (including 2011C variant).

• Materials: All wetted parts are stainless steel, providing excellent corrosion resistance and durability for demanding industrial environments.

• Pipe connections: 1/2” or 3/4” (15-20 mm), with a 360° universal connector for convenient in-line installation.

• Maximum operating pressure: 400 psig (28 barg), suitable for high-pressure steam systems.

• Capacity: Up to 880 lb/hr (400 kg/hr), efficiently handling high condensate flow rates.

• Dimensions and installation: Approximately 50 mm face-to-face removal length; 635 mm bolt clearance required for installation. The lightweight, compact design is suitable for applications with limited space.

• Durability: Resistant to freeze damage and requires no additional protection. Tamper-resistant sealed packaging helps ensure safe, reliable operation.

Product Advantages

Armstrong 2011 stainless steel inverted bucket steam trap delivers strong performance in energy savings, installation convenience, and maintenance cost reduction:

• Energy-efficient operation: Based on the density-difference principle, it rapidly discharges condensate and air, reducing steam loss and improving system efficiency. Compared with conventional steam traps, it can significantly reduce energy consumption.

• Easy installation and replacement: Equipped with an IS-2 connector or standard connector, it supports fast in-line replacement without interrupting piping operation. The 360° rotatable design accommodates various installation orientations.

• Corrosion resistance and durability: The all-stainless-steel construction resists chemical corrosion and high temperatures. Freeze resistance supports reliable operation in cold environments.

• Expandable compatibility: Can be integrated with Armstrong Pop Drain drainage systems, TrapAlert™ monitors, and SteamEye™ remote steam monitoring to enhance intelligent system management.

• Cost effectiveness: The lightweight design reduces transportation costs, while long service life reduces replacement frequency. Suitable for food processing, chemical processing, pharmaceutical, and HVAC systems.

These advantages make Armstrong 2011 a preferred product for steam management systems. See the maintenance guide: Armstrong Steam Trap Service Guide.

Applications

Armstrong 2011 inverted bucket steam trap is widely used in industrial applications, including:

• Steam heating systems: Such as heat exchangers, dryers, and cooking equipment, ensuring efficient heat transfer.

• Process control: Chemical plants, pharmaceutical production areas, and food processing lines requiring high-pressure steam management.

• HVAC and buildings: Steam supply systems in commercial buildings requiring reliable condensate drainage.

• High-pressure environments: Operation up to 200 PSI (for specific submodels), suitable for heavy industrial applications.

When a steam system requires efficient condensate removal, Armstrong 2011 provides a customizable solution. Refer to the application catalog: Armstrong Steam Trap Range.
