Applications:
Ideal for transferring water, antifreeze, fuel, and other fluids in industrial, mining, agricultural, and hazardous environments where explosion-proof equipment is required.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and compatibility with existing equipment.
• Ensure all electrical installations comply with local regulations and ATEX requirements
• Verify correct porting (BSPT) and fluid compatibility before installation
• Regularly inspect diaphragms, seats, and balls for wear and replace as needed
• Follow manufacturer guidelines for wiring and motor control
• Use only recommended replacement parts (e.g., Santoprene seats, balls, diaphragms)
• Periodically check for leaks and tighten connections as necessary
• Clean pump internals after use with abrasive or slurry fluids
