Applications:
Industrial fluid transfer, vehicle service (oil evacuation, oil transfer), water, antifreeze, and fuel transfer in mining, agriculture, and other heavy-duty environments
Installation Notes:
- Using genuine GRACO parts ensures optimal performance, reliability, and safety. Non-genuine parts may compromise pump efficiency and longevity.
- Ensure proper alignment of inlet and outlet connections
- Use appropriate thread sealant or gaskets for leak-free installation
- Follow recommended air pressure and flow settings for optimal performance
- Regularly inspect diaphragms, seats, and balls for wear and replace as needed
- Refer to the specific installation manual for vertical outlet models to ensure correct orientation and mounting
- Periodically check for leaks and tighten connections as necessary
- Replace diaphragms and seals according to the maintenance schedule
- Clean pump internals if handling fluids with suspended solids
- Lubricate moving parts as recommended by GRACO
