Applications:
Ideal for tough transfer jobs in industries such as mining, agriculture, chemical processing, and manufacturing. Suitable for handling viscous, abrasive, or solid-laden fluids.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety. Non-genuine parts may compromise pump efficiency and longevity.
• Ensure proper alignment and secure mounting to prevent vibration and leaks
• Follow electrical safety guidelines for 240V AC motor installation
• Use appropriate piping and fittings for BSP end ports
• Check for correct diaphragm and ball material compatibility with the fluid being transferred
• Regularly inspect and maintain seals and diaphragms to prevent leaks and extend service life
• Periodically check for wear on diaphragms, balls, and seats
• Lubricate moving parts as recommended by the manufacturer
• Monitor for unusual noise or vibration, which may indicate maintenance needs
• Follow the manufacturer’s guidelines for cleaning and replacing components
