• Reliable, robust construction for demanding environments
• Easy maintenance and long diaphragm life

Applications:
Ideal for transferring chemicals, solvents, and other aggressive fluids in industrial, manufacturing, and processing environments. Suitable for applications requiring chemical resistance and reliable, low-maintenance operation.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and compatibility with existing equipment.
• Ensure proper alignment and secure mounting of the pump
• Use appropriate fittings and hoses rated for the intended fluid and pressure
• Install a fluid pressure relief valve at the pump outlet to prevent overpressurization and potential damage
• Regularly inspect and maintain diaphragms, balls, and seals for wear and proper function
• Follow manufacturer guidelines for installation and maintenance
• Use only recommended replacement parts and accessories
• Monitor air supply and fluid pressure to avoid exceeding maximum ratings
