The GRACO A22420 is a pneumatic chemical injection pump designed for high-flow, high-pressure chemical injection applications. It features a Chromex-coated plunger and TFE/P seals, ensuring durability and chemical resistance. This pump is intended for use in industrial environments where reliable, continuous chemical transfer is required.

Key Features:

• Pneumatic Chemical Injection Pump
• Python XL-DA, 4-1/2 in Air Motor, 1 in Plunger
• Chromex-coated plunger, TFE/P seals
• Designed for chemical injection applications in non-hazardous locations
• CE Approved
• Double acting: pumps fluid in both directions of the stroke for continuous flow
• Self-priming and anti-locking: prevents air from stalling the pump
• Simple design for quick seals replacement and ease of serviceability
• Vertical installation for reduced footprint
• Environmentally friendly: recoverable exhaust gas with kit, less fugitive emissions
• Adjustable packing seals for better sealing and increased pump life
• Poppet style check valves for reliable operation
• Hollow pump rod design allows flow in both directions

Applications:
Suitable for chemical injection applications requiring higher flows at high pressures, such as in industrial, mining, and agricultural settings.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety in chemical injection systems.
• Install pump vertically to minimize footprint and ensure proper operation
• Use appropriate tools and follow manufacturer guidelines for installation
• Regularly inspect and replace seals as needed for maintenance
• Consider adding a gas recovery kit for environmentally friendly operation
• Follow all safety procedures when handling chemicals
• Ensure compatibility of pump materials with the chemicals being transferred
