• Air-Operated Double Diaphragm Pump
• Husky 1590, 1-1/2" NPT
• PVDF housing, aluminum center section, PVDF seats, fluoroelastomer balls and diaphragms
• Maximum free flow delivery: 100 gpm (378.5 lpm)
• Maximum fluid working pressure: 120 psi (8.4 bar, 0.84 MPa)
• Industrial fluids, aggressive chemicals, corrosive liquids
• Patented, high-reliability closed center air valve
• Online serviceable
• Epoxy-coated air section for tough environments
• Durable construction for harsh industrial use

Applications:
Industrial fluid transfer, chemical processing, wastewater, and other applications requiring resistance to aggressive or corrosive fluids.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and compatibility with existing equipment.
• Ensure proper alignment of pump and piping
• Use appropriate gaskets and seals for chemical compatibility
• Follow manufacturer’s torque specifications for connections
• Regularly inspect diaphragms and seals for wear and replace as needed
• Perform routine inspections of diaphragms, balls, and seats
• Clean pump internals after use with aggressive chemicals
• Lubricate moving parts as recommended by GRACO
• Keep air supply clean and dry to prevent valve issues
