Applications:
Used for evacuating and transferring fluids in industrial, mining, agricultural, and maintenance environments. Suitable for handling fluids with small solids and for remote or automated operation.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and longevity of the equipment.
• Read all instruction manuals, tags, and labels before operating the equipment.
• Use the equipment only for its intended purpose and within specified pressure and temperature limits.
• Ensure proper lubrication of moving parts during assembly and maintenance.
• For remote operation, use CycleFlo or an external valve control system as required.
• Regularly inspect and maintain diaphragms, seats, and balls to prevent leaks and ensure reliable operation.
