The GRACO DB5888 is an air-operated double diaphragm pump featuring a PVDF (polyvinylidene fluoride) fluid housing, aluminum center section, and flouroelastomer (FKM) seats, balls, and diaphragm. It is designed for reliable, high-flow transfer of aggressive or corrosive fluids in industrial applications.

Key Features:

• Air-Operated Double Diaphragm Pump
• Husky 1590, 1-1/2" NPT
• PVDF fluid housing, aluminum center section, FKM (flouroelastomer) seats, balls, and diaphragm
• Up to 100 gpm (378.5 lpm)
• Maximum fluid working pressure: 120 psi (8.4 bar, 0.84 MPa)
• Compatible with a wide range of aggressive and corrosive fluids due to PVDF and FKM materials
• Patented, high-reliability closed center air valve
• Externally accessible air valve for easy servicing without uninstalling the pump
• Up to 5 times longer diaphragm life compared to other air-operated diaphragm pumps in its class
• Fewer parts than industry peers for easier maintenance
• Compact, portable size

Applications:
Ideal for transferring aggressive, corrosive, or abrasive fluids in industries such as chemical processing, mining, agriculture, and general industrial maintenance. Suitable for applications requiring high flow rates and resistance to harsh chemicals.

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 tight and leak-free before operation
• Follow manufacturer guidelines for air supply and pressure settings
• Regularly inspect and maintain the air valve and diaphragm for optimal performance
• Use appropriate personal protective equipment when handling aggressive fluids
