Applications:
Ideal for transferring fluids, slurries, and abrasives in industrial environments such as mining, agriculture, and manufacturing. Suitable for applications requiring robust, low-maintenance, and energy-efficient fluid handling.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and longevity of the pump. Non-genuine parts may compromise safety and efficiency.
• Ensure proper alignment and secure mounting of the pump
• Verify electrical supply matches pump requirements (240/415V AC)
• Check all connections for leaks before operation
• Follow GRACO’s recommended maintenance schedule for diaphragm and ball replacement
• Consult the equipment manual for specific installation and maintenance procedures
• Regularly inspect wetted parts for wear and replace as needed
• Monitor pump performance and address any unusual noise or vibration promptly
• Keep the pump and surrounding area clean to prevent contamination
