The GRACO Python Pneumatic Chemical Injection Pump is a robust, stainless steel pump designed for the precise injection of chemicals such as corrosion inhibitors, methanol, and scavengers in industrial applications. It is intended for use within GRACO equipment to deliver reliable, high-pressure chemical dosing in demanding environments.

Key Features:

• Pneumatic Chemical Pump
• Python, 1-1/4 in Air Motor, 3/16 in Plunger (Note: 3/16 in Plunger not found in official specs; closest official models use 1/4 in or 1/2 in Plunger. For A25143, assume 3/16 in as per your query, but confirm with GRACO for accuracy.)
• Stainless Steel
• Corrosion Inhibitors, Methanol, Scavengers
• ATEX Approved
• Stainless steel construction for corrosion resistance
• Chromex-coated plunger rod for durability
• HNBR seals for chemical compatibility
• Designed for high reliability and ease of maintenance
• ATEX certification for use in explosive atmospheres

Applications:
Used for injecting chemicals such as corrosion inhibitors, methanol, and scavengers in industrial, oil & gas, and process applications where precise chemical dosing and safety in hazardous environments are required.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and safety in hazardous environments. Non-genuine parts may compromise performance and safety.
• Mount the pump vertically using the inlet port at the bottom, as indicated by the flow arrow
• Ensure the inlet plumbing is strong enough to support the pump’s weight
• Install a y-strainer or chemical filter before the pump inlet to prevent debris from reaching the pump seals
• Connect the air supply with appropriate shutoff valves, filters, and regulators as per the installation diagram
• Consult the GRACO manual for specific installation and maintenance procedures
• Regularly inspect and maintain seals and plunger rod
• Use only compatible chemicals as specified
• Follow all safety guidelines for ATEX-certified equipment
• Replace filters and strainers as needed to prevent contamination
