The GRACO A25352 is a pneumatic chemical injection pump designed for reliable, high-pressure chemical dosing in industrial environments. Constructed primarily from stainless steel, it is engineered for use with corrosion inhibitors, methanol, and scavengers, making it ideal for wells with low gas pressure. The pump features a Chromex-coated plunger and HNBR seals for enhanced durability and chemical resistance.

Key Features:

• Pneumatic Chemical Pump
• Python XL, 3-1/2 in Air Motor, 1/2 in Plunger
• Stainless Steel (wetted parts and main body)
• Maximum Flow Rate: 170 GPD
• Maximum Working Pressure: 8700 psi (60 MPa)
• Corrosion inhibitors, methanol, scavengers
• ATEX Approved
• Chromex-coated plunger rod for wear resistance
• HNBR seals for chemical compatibility and durability
• Three stroke adjustment positions for precise dosing
• Easy to operate and maintain
• Environmentally friendly with 97% recoverable exhaust gas
• Reduced emissions of volatile methane
• Available with bracket or pedestal mounting

Applications:
Ideal for chemical injection in wells with low gas pressure, including oil and gas, mining, and industrial processing environments where reliable, high-pressure chemical dosing is required.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and compatibility with existing equipment.
• Ensure proper alignment and secure mounting (bracket or pedestal)
• Connect air supply according to specifications (maximum air inlet pressure: 100 psi)
• Verify compatibility of chemical media with pump materials and seals
• Follow manufacturer guidelines for maintenance intervals and seal replacement
• Regularly inspect for leaks and wear, especially in harsh environments
