The GRACO D73GGG is an air-operated diaphragm pump, constructed primarily from aluminum, designed for reliable fluid transfer in industrial applications. It is intended for use within GRACO equipment to handle a variety of fluids, including those requiring robust and corrosion-resistant materials.

Key Features:

• Air-operated diaphragm pump
• 1040A (1" NPT inlet/outlet)
• Aluminum
• Compatible with various industrial fluids; requires grounded fluid hoses
• Stall-free, low pulsation air valve for smooth operation
• Easy maintenance with accessible components
• Reliable for continuous duty cycles
• Push-type connectors for flexible air line connections

Applications:
Industrial fluid transfer, including handling of chemicals, oils, and other compatible fluids. Suitable for environments requiring robust and corrosion-resistant pumps.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety. Non-genuine parts may compromise pump efficiency and longevity.
• Connect air line to pump as per instructions
• Use grounded fluid hoses for safety
• Connect 1/4" O.D. tubing to push-type connectors on air motor; other sizes/types may be used by replacing connectors
• Ensure air pressure at connectors is at least 30% of air motor pressure for proper operation
• Screw fluid fitting into pump inlet securely
• Avoid fluid inlet pressure exceeding 25% of outlet working pressure to prevent inefficient operation
• Regularly inspect and replace worn seals and diaphragms
• Ensure all connections are secure and leak-free
• Follow manufacturer guidelines for lubrication and cleaning
