• Air-operated double diaphragm pump
• Husky 2150, 2 in. (51 mm) NPT
• Stainless steel center section, stainless steel seats, PTFE balls, PO diaphragm
• Up to 150 gpm (568 lpm)
• Up to 120 psi (8.4 bar, 0.84 MPa)
• Compatible with a wide range of fluids, including corrosive and abrasive liquids
• Stall-free low pulsation air valve for smooth, rapid changeover
• Up to 40% more efficient than comparable pumps
• Up to 5 times longer diaphragm life
• Fewer parts than industry peers, externally accessible air valve for easy servicing
• Lube-free operation
• Epoxy-coated air section for tough environmental conditions
• Maximum pumpable solids: 0.25 in (6.3 mm)
• Maximum suction lift: 20 ft (6.1 m) dry

Applications:
Ideal for industrial fluid transfer, including handling corrosive, abrasive, or viscous liquids in mining, agriculture, chemical processing, and other demanding environments.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety, and maintains warranty coverage.
• Ensure the pump is properly grounded before operation to prevent fire and explosion hazards
• Follow torque specifications: 190–220 in-lb (22–25 N·m) for stainless steel models
• Assemble all parts as shown in the manual, ensuring arrows on fluid covers point toward the outlet manifold
• Clean and inspect all parts for wear or damage before reassembly
• Use medium-strength (blue) thread locker on threads as recommended
• Regularly inspect and replace worn or damaged parts
• Keep the air section clean and free from excessive lubrication
• Service the air valve externally without removing the diaphragm pump for faster maintenance
