• Maximum Working Pressure: 6.9 MPa (1000 psi); Maximum Air Inlet Pressure: 13.79 bar (200 psi)
• Corrosion Inhibitors, Methanol, Scavengers
• CE Approved
• Chromex-coated plunger rod for enhanced durability
• HNBR seals for chemical resistance
• Maximum continuous cycle rate: 60 cycles per minute
• Designed for vertical mounting
• Easy access for maintenance and service

Applications:
Industrial chemical injection, well-site chemical dosing, corrosion inhibitor injection, methanol injection, scavenger injection

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance. Non-genuine parts may compromise safety and equipment longevity.
• Mount the pump vertically from the 1/4 female NPT inlet port (bottom of pump)
• Ensure 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 pump seals
• Connect air supply with appropriate shutoff valve, filter, regulator, and lubricator as per typical installation diagram
• Verify all connections and pressure settings before operation
• Regularly inspect and replace seals as needed
• Check for leaks and proper operation
• Clean or replace filters to prevent contamination
• Follow manufacturer’s recommended maintenance schedule
