The GRACO A22204 is a pneumatic chemical injection pump designed for reliable, high-pressure chemical transfer in industrial settings. It features a 2-1/2 inch air motor, a 3/8 inch ceramic-coated plunger, and FFKM seals for chemical resistance. This pump is intended for use in non-hazardous locations and is suitable for applications requiring robust, continuous flow operation.

Key Features:

• Pneumatic Chemical Pump
• Python XL-DA, 2-1/2 in Air Motor, 3/8 in Plunger
• Ceramic-coated plunger, FFKM seals, Chromex rod coating (note: product listing specifies ceramic-coated plunger, but standard XL-DA 2-1/2 in models list Chromex coating; confirm with supplier for A22204 specifics)
• Maximum working pressure: 30.6 MPa (306 bar, 4400 psi)
• Designed for non-hazardous location chemical injection applications
• CE Approved
• Double acting: pumps fluid in both directions of the stroke for increased flows
• Self-priming and anti-locking: prevents air from being trapped inside the air motor and stalling the pump
• Simple pump design for quick seals replacement
• Ease of serviceability
• Reliable, continuous flow operation
• Environmentally friendly with less fugitive emissions

Applications:
Chemical injection in industrial, manufacturing, and processing environments where high-pressure, reliable chemical transfer is required. Suitable for non-hazardous locations.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety. Non-genuine parts may compromise pump efficiency and longevity.
• Install pump vertically for reduced footprint and optimal performance
• Ensure proper alignment and secure mounting
• Use appropriate fittings and hoses rated for the maximum working pressure
• Follow manufacturer’s guidelines for air supply and fluid connections
• Regularly inspect seals and plunger for wear and replace as needed
• Perform routine inspections and maintenance as recommended by GRACO
• Replace seals and other wear parts with genuine GRACO components
• Keep the pump clean and free from debris
• Monitor for leaks and unusual noises
