• Duplex chemical injection pump
• Wolverine Advanced, 3/8 in plunger, 12 VDC, 1/11 HP (67 Watt) motor
• 316 stainless steel wetted parts, HNBR seals
• Compatible with aggressive chemicals; HNBR, FKM, FKM-ETP, and FFKM seals available across the line
• Easily replaceable seals (less than 10 minutes)
• Precision stroke adjustment (1/2 in to 1 in)
• Modular, serviceable design
• Long-lasting, adjustable fluid packing
• Low friction drivetrain for electrical efficiency
• Designed for years of operation before simple repairs

Applications:
Used for injecting corrosion inhibitors, methanol, scavengers, and other chemicals at well sites and pipelines to protect from corrosion, plugging, and freezing. Suitable for oilfield, pipeline, and industrial environments.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance. Non-genuine parts may compromise safety and equipment longevity.
• Follow manufacturer guidelines for electrical and mechanical installation
• Ensure proper grounding and electrical safety for hazardous locations
• Regularly inspect and maintain seals and wetted parts
• Use appropriate chemical-compatible seals for the application
• Consult the manual for specific wiring and setup instructions
• Replace seals as needed, typically every 6–12 months or as indicated by wear
• Monitor injection rates and adjust stroke as required
• Keep the pump and surrounding area clean and free from debris
• Check for leaks and unusual noises during operation
