The GRACO A25408 is a pneumatically operated chemical injection pump designed for high-pressure, continuous flow applications. It features a 4-1/2 inch air motor, a Chromex coated 5/8 inch plunger, and FKM-ETP seals. This pump is engineered for reliable chemical injection in demanding industrial environments and is CE approved for use in regulated markets.

Key Features:

• Pneumatic chemical injection pump
• Python XL, 4-1/2 in Air Motor, 5/8 in Plunger
• Chromex coated plunger, FKM-ETP seals, robust metal housing
• Capable of operating up to 12,000 psi (see instruction manual for exact maximums for this configuration)
• Designed for integration with GRACO chemical injection systems and compatible with a wide range of chemicals
• CE Approved
• Double-acting operation for continuous flow and prevention of air locking (for XL-DA models; standard XL is single-acting but similar in robustness)
• High efficiency air valve minimizes fugitive emissions
• Easy to operate and maintain
• Reliable performance in harsh environments (-40° to 176°F / -40° to 80°C)
• Low noise operation (sound pressure: 70.2 dBA for 4.5 in. air motor)

Applications:
Chemical injection in oil & gas, mining, agriculture, and industrial processes requiring precise, high-pressure fluid delivery.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and warranty compliance.
• Follow all instructions in the GRACO Python XL instruction manual for installation and setup
• Ensure proper alignment and secure mounting of the pump
• Use recommended fittings and adapters for fluid and air connections
• Prime the pump according to manufacturer guidelines before operation
• Regularly inspect seals and plunger for wear and replace as needed
