The GRACO D5B336 is an air-operated double diaphragm pump with a polypropylene (PP) center section, stainless steel (SS) seats and balls, and a Santoprene (SP) diaphragm. It is designed for reliable, leak-free transfer of fluids in industrial and maintenance applications, particularly where corrosion resistance and chemical compatibility are required.

Key Features:

• Air-operated double diaphragm pump
• Husky 515 PP 1/2 in. (13 mm) BSP Standard Pump
• Polypropylene (PP) center section, stainless steel (SS) seats and balls, Santoprene (SP) diaphragm
• Up to 15 gpm (57 lpm)
• Maximum fluid working pressure: 100 psi (7 bar, 0.7 MPa)
• Compatible 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
• Reliable air valve for years of dependable performance
• Split manifold option available for pumping multiple fluids without mixing

Applications:
Ideal for transferring fluids in industrial, maintenance, and lubrication systems, including applications in mining, agriculture, and manufacturing where chemical resistance and reliability are essential.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and longevity of the pump, as well as compatibility with existing GRACO equipment.
• Ensure all connections are tight and leak-free before operation
• Follow manufacturer guidelines for air supply pressure (operates on as little as 20 psi/1.4 bar)
• Regularly inspect and maintain air valve and ball checks for reliable performance
• Use appropriate personal protective equipment during installation and maintenance
• Regularly check for leaks and wear on diaphragms and seals
• Clean pump components as recommended to prevent clogging and ensure smooth operation
• Replace worn or damaged parts with genuine GRACO components
