The GRACO DG2666 is a remote air-operated double diaphragm (AODD) pump designed for robust fluid transfer applications. It features a polypropylene fluid section, aluminum center section, and Santoprene seats, balls, and diaphragm for chemical resistance and durability. This pump is intended for use in industrial environments requiring reliable, lube-free operation and compatibility with a wide range of fluids.

Key Features:

• Air-Operated Double Diaphragm Pump (AODD)
• Husky 2150, 2" NPT (51 mm)
• Polypropylene fluid section, aluminum center section, Santoprene seats, balls, and diaphragm
• Up to 150 gpm (568 LPM)
• Up to 120 psi (8.4 bar, 0.84 MPa)
• Compatible with a wide range of industrial fluids, especially those requiring chemical resistance
• Up to 5 times longer diaphragm life compared to other air-operated diaphragm pumps
• Fewer parts than industry peers; air valve is externally accessible for quick, easy servicing without uninstalling the pump
• Lube-free operation
• Epoxy-coated air section for tough environmental conditions
• Stall-free, low pulsation air valve for smooth operation

Applications:
Ideal for transferring aggressive, abrasive, or viscous fluids in industries such as mining, agriculture, chemical processing, and general industrial applications. Suitable for remote installations where robust, reliable pumping is required.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and compatibility with existing equipment. Non-genuine parts may compromise safety and efficiency.
• Ensure proper alignment and secure mounting of the pump
• Use appropriate piping and fittings for the intended fluid and pressure
• Follow GRACO’s recommended maintenance schedule for diaphragm and valve inspection
• Check for leaks and proper air supply before operation
• Refer to the GRACO Husky 2150 manual for detailed installation and maintenance procedures
