The GRACO Husky 15120 is an air-operated double diaphragm pump constructed primarily from polypropylene, with a polypropylene center section and seats, FKM balls, and PTFE overmolded diaphragms. It is designed for reliable, efficient fluid transfer in demanding industrial applications, including handling high-viscosity materials and abrasive fluids.

Key Features:

• Air-operated double diaphragm pump
• Husky 15120, 1.5 in (38 mm) ANSI/DIN flange
• Polypropylene (center section, seats), FKM balls, PTFE overmolded diaphragms
• Up to 120 gpm (454 lpm) with 2-piece bolt-through diaphragms; up to 115 gpm (435 lpm) with overmolded diaphragms
• Maximum fluid working pressure: 125 psi (8.6 bar, 0.86 MPa); Air pressure operating range: 20–125 psi (1.4–8.6 bar)
• Suitable for a wide range of fluids, including high-viscosity and abrasive materials; available in polypropylene and PVDF
• Stall-free low pulsation air valve for smooth, rapid changeover
• One-piece center section reduces leaks and maintenance
• Up to 5 times longer diaphragm life compared to other air-operated diaphragm pumps
• Lube-free operation
• Compact, portable size
• Expanded material offering for diverse applications

Applications:
Ideal for fluid transfer in industrial, chemical, mining, and agricultural settings, especially where high flow rates, reliability, and resistance to corrosive or abrasive fluids are required.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety. Non-genuine parts may compromise pump efficiency and longevity.
• Ensure all connections are secure and leak-free before operation
• Use appropriate protective equipment as recommended by the fluid and solvent manufacturer (e.g., protective eyewear, hearing protection, respirators, protective clothing, gloves)
• Check diaphragm and ball condition regularly to maintain maximum suction lift and flow rate
• Follow all safety instructions and warnings in the product manual
• Store and operate the pump within recommended temperature ranges to prevent damage
• Regularly inspect diaphragms, balls, and seats for wear or damage
• Replace worn or damaged parts promptly with genuine GRACO components
• Clean the pump and associated piping as needed to prevent buildup and ensure efficient operation
