The GRACO A25500 is a pneumatically operated chemical injection pump designed for high-pressure chemical dosing applications. It features a 2-1/2 inch air motor, a Chromex coated 1/4 inch plunger, and FKM (Fluoroelastomer) seals. This pump is ATEX approved, making it suitable for use in potentially explosive atmospheres. It is intended for reliable, continuous chemical injection in demanding industrial environments.

Key Features:

• Pneumatic chemical injection pump
• Python XL, 2-1/2 in air motor, 1/4 in plunger
• Chromex coated plunger, FKM seals, robust metal housing
• Capable of operating up to 12,000 psi
• Designed for integration with GRACO chemical injection systems and compatible with a wide range of chemicals
• ATEX approved
• Double-acting operation for continuous flow and prevention of air locking (note: double-acting is a feature of Python XL-DA, not standard Python XL; for A25500, confirm with manual as it may be single-acting)
• High efficiency air valve minimizes fugitive emissions
• Proven Merkur® air motor technology
• Easy to operate and maintain
• Reliable performance in harsh environments
• Environmental temperature range: -40° to 176°F (-40° to 80°C)

Applications:
Ideal for chemical injection in oil and gas, mining, water treatment, and other industrial processes requiring precise, high-pressure chemical dosing.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and compliance with industry standards.
• Follow all instructions in the GRACO equipment manual for installation and maintenance
• Ensure proper alignment and secure mounting of the pump
• Use appropriate fittings and hoses rated for the intended pressure and chemical compatibility
• Regularly inspect seals and plunger for wear and replace as needed
• Maintain clean and dry compressed air supply to the air motor
• Perform routine maintenance checks as recommended by GRACO
• Keep spare seals and plungers on hand for quick replacement
• Monitor pump performance and address any leaks or irregularities promptly
