Description
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
