The GRACO 654517 Husky 15120 is a polypropylene air-operated double diaphragm pump featuring a polypropylene center section, stainless steel seats, and fluoroelastomer balls and diaphragm. It is designed for reliable, efficient, and low-maintenance transfer of a wide range of fluids in industrial applications.

Key Features:

• Air-operated double diaphragm pump
• Husky 15120, 1-1/2 in (38.1 mm) ANSI center and end-porting options
• Polypropylene center section, stainless steel seats, fluoroelastomer balls and diaphragm
• Maximum free flow delivery: 5.0 gpm (18.9 lpm) (Note: Some sources list much higher flow rates for larger models or different configurations; for this specific part, 5.0 gpm is documented for Husky 15120 plastic pumps). However, GRACO’s main product page lists up to 120 gpm (454 lpm) for Husky 15120, but this may refer to larger or different configurations. For this specific part (654517), use 5.0 gpm (18.9 lpm) as per the detailed specification.
• Maximum fluid working pressure: 100 psi (7 bar, 0.7 MPa) (Note: Some sources list up to 125 psi (8.6 bar, 0.86 MPa) for Husky 15120, but this may depend on configuration and materials). For this specific part (654517), use 100 psi (7 bar, 0.7 MPa) as per the detailed specification.
• Compatible with a wide range of fluids, especially corrosive and abrasive liquids, due to polypropylene and fluoroelastomer construction
• Stall-free low pulsation air valve for smooth and rapid changeover
• One-piece center section eliminates leaks and reduces maintenance
• Up to 40% more efficient than other double diaphragm pumps
• 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 transferring corrosive, abrasive, or viscous fluids in industries such as chemical processing, water treatment, mining, agriculture, and general industrial applications. Suitable for applications requiring reliable, low-maintenance fluid transfer with minimal pulsation.

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 tight and leak-free before operation
• Use appropriate gaskets and seals for the intended fluid
• Follow GRACO’s recommended maintenance schedule for diaphragm and ball inspection
• Install in a location with adequate ventilation and access for maintenance
• Check for proper alignment and secure mounting to prevent vibration and wear
