The GRACO D52D07 is an air-operated double diaphragm pump featuring a polypropylene center section, urethane duckbill seats, and a Buna-N diaphragm. It is designed for reliable, leak-free transfer of fluids in industrial applications, especially where chemical compatibility and safety are priorities.

Key Features:

• Air-operated double diaphragm pump
• Husky 515, 1/2" NPT
• Polypropylene center section, urethane duckbill seats, Buna-N diaphragm
• Up to 15 gpm (56.7 lpm)
• Maximum fluid working pressure: 100 psi (0.7 MPa)
• Designed for use with a wide range of industrial fluids, especially those requiring chemical resistance
• Stall-free low pulsation air valve for smooth and rapid changeover
• Bolt-through fluid cover design eliminates leaks and enhances safety
• No mechanical seals to cause fluid leaks or failures
• Runs quietly at less than 85 dBa with remote muffler capability
• Easy-to-service air valve and ball checks
• Operates on as little as 20 psi (1.4 bar, 0.14 MPa) air supply
• Split manifold option for pumping multiple fluids without mixing
• Reliable air valve for years of dependable performance

Applications:
Ideal for transferring chemicals, solvents, and other industrial fluids in environments requiring chemical resistance and leak-free operation. Suitable for use in manufacturing, processing, and maintenance applications across various industries.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety. Non-genuine parts may compromise pump integrity and void warranties.
• Ensure all connections are secure and leak-free before operation
• Use appropriate thread sealant for NPT connections
• Check air supply pressure and ensure it is within the recommended range (minimum 20 psi)
• Inspect diaphragms and seats regularly for wear and replace as needed
• Follow manufacturer guidelines for maintenance intervals and procedures
• Regularly inspect and maintain air valve and ball checks for optimal performance
• Use remote muffler for reduced noise in sensitive environments
• Consider split manifold option if pumping multiple fluids to prevent cross-contamination
