• Aluminum, 316 stainless steel, polypropylene, PVDF, or ductile iron
• Up to 150 gpm (568 lpm)
• Up to 120 psi (8.4 bar, 0.84 MPa)
• Compatible with a wide range of industrial fluids, including those with solids up to 0.25 in
• Lube-free operation
• Epoxy-coated air section for tough environmental conditions
• Available with standard or remote air valve
• Stall-free, low pulsation air valve for smooth operation
• High efficiency and reliability
• Easy maintenance and long diaphragm life

Applications:
Ideal for transferring fluids with solids in industrial, mining, chemical, and agricultural applications. Suitable for use in harsh environments where corrosion resistance and durability are required.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety. Non-genuine parts may compromise pump efficiency and longevity.
• Ensure proper alignment of inlet and outlet connections
• Use appropriate thread type (NPT or BSP) as required
• Check for leaks after installation
• Follow recommended maintenance schedules for diaphragm and valve inspection
• Use compatible fluids and avoid exceeding maximum solids size (0.25 in)
