The GRACO A22206 is a pneumatically operated, double-acting chemical injection pump designed for high-pressure, high-flow chemical injection applications. It features a 2-1/2 inch air motor and a 1/2 inch Chromex-coated plunger, with HNBR seals for chemical resistance. The pump is constructed primarily from stainless steel and is intended for use in demanding industrial environments where reliable, continuous chemical injection is required.

Key Features:

• Pneumatic, double-acting chemical injection pump
• Python XL-DA, 2-1/2 in Air Motor, 1/2 in Plunger
• Stainless steel (wetted parts), Chromex-coated plunger, HNBR seals
• Designed for chemical injection in industrial applications; not for use with sour gas or in explosive atmospheres
• CE Approved
• Double-acting operation for continuous flow and increased efficiency
• Self-priming and anti-locking to prevent air entrapment and stalling
• Simple design for quick seals replacement and ease of maintenance
• Vertical installation for reduced footprint
• Environmentally friendly with options for gas recovery and reduced 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 of stroke

Applications:
Chemical injection in oil and gas, mining, industrial processing, and other applications requiring reliable, high-pressure chemical delivery.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and compatibility with existing systems.
• Install the pump vertically to minimize footprint and ensure proper operation
• Connect fluid lines securely from the pump outlet to the injection point
• Install a fluid pressure relief valve on the outlet side for safety
• Ensure all connections are tight and leak-free before operation
• Regularly inspect and replace seals as needed for continued reliability
• Regularly check and replace seals to prevent leaks and maintain efficiency
• Monitor for signs of wear or damage, especially in harsh environments
• Use only recommended replacement parts and lubricants
• Consult the manual for specific maintenance intervals and procedures
