The GRACO DFF666 Husky 2150 is a cast iron air operated double diaphragm (AODD) pump designed for reliable, high-volume fluid transfer in industrial applications. It is constructed with a cast iron fluid section for durability and is intended for use in demanding environments where robust, efficient, and maintenance-friendly pumping is required.

Key Features:

• Air Operated Double Diaphragm (AODD) Pump
• Husky 2150, 2" (51 mm) ANSI end-porting
• Cast Iron (fluid section), with options for other materials (aluminum, stainless steel, polypropylene, PVDF) in other variants
• Up to 150 gpm (568 lpm)
• Up to 120 psi (8.4 bar, 0.84 MPa)
• Compatible with a wide range of industrial fluids; suitable for use in various GRACO equipment and systems
• Stall-free low pulsation air valve for smooth and rapid changeover
• Up to 40% more efficient than previous models
• Up to 5 times longer diaphragm life compared to other AODD pumps
• Fewer parts than industry peers; complete air valve is externally accessible for fast, easy servicing without removing the pump
• Lube-free operation
• Epoxy-coated air section for tough environmental conditions
• Maximum pump speed: 145 cycles per minute
• Maximum suction lift: 20 ft (6.1 m) dry
• Maximum size pumpable solids: 0.25 in (6.3 mm)

Applications:
Ideal for industrial fluid transfer, including chemical processing, mining, agriculture, and other demanding environments requiring robust, efficient, and maintenance-friendly pumping solutions.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety. Non-genuine parts may compromise pump efficiency and longevity.
• Ensure proper alignment and secure mounting of the pump
• Use appropriate piping and fittings for the intended fluid and pressure
• Follow all safety guidelines during installation and maintenance
• Regularly inspect and maintain the air valve and diaphragms for optimal performance
• Consult the equipment manual for specific installation and maintenance procedures
