The GRACO 649007 is an air-operated double diaphragm pump designed for reliable fluid transfer in industrial applications. It features a polypropylene (PP) center section and seats, PTFE balls, and a polyolefin (PO) diaphragm, making it highly resistant to strong chemicals such as alkalis, acids, and organic solvents. This pump is engineered for use in demanding environments where chemical compatibility and leak-free operation are essential.

Applications:
Ideal for transferring a wide range of chemicals, including aggressive fluids, in industries such as mining, agriculture, chemical processing, and general industrial maintenance. Suitable for applications requiring leak-free, low-maintenance, and reliable fluid transfer.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and compatibility with existing equipment. Non-genuine parts may compromise safety and efficiency.
• Ensure all connections are secure and properly aligned before operation
• Use appropriate thread sealant on NPT connections to prevent leaks
• Check for correct air supply and pressure settings as per manufacturer recommendations
• Regularly inspect diaphragm and valve components for wear and replace as needed
• Follow GRACO’s recommended maintenance schedule for best performance and longevity
