The GRACO 15B491 is a fluoroelastomer ball designed for use in high-sanitation air-operated double diaphragm (AODD) pumps, such as those in the SaniForce™ series. It is intended to replace or upgrade the ball valve component within the pump, ensuring reliable sealing and chemical resistance in demanding applications.

Key Features:

• Ball valve component
• Fluoroelastomer (FKM)
• Designed for use in GRACO SaniForce™ and compatible AODD pumps
• High chemical resistance
• Durable, non-sticking material
• Suitable for high-sanitation environments
• Easy to replace as part of maintenance kits

Applications:
Used in food, dairy, beverage, and pharmaceutical industries where high sanitation and chemical resistance are required. Commonly installed in GRACO SaniForce™ and similar AODD pumps for reliable fluid transfer.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and compliance with industry standards. Non-genuine parts may compromise pump integrity and sanitation.
• Ensure pump is depressurized and isolated before installation
• Follow manufacturer’s instructions for disassembly and reassembly of the ball valve section
• Inspect all components for wear or damage during maintenance
• Use appropriate tools and safety precautions
• Regularly inspect ball and seat for wear or contamination
• Replace ball and seat as part of routine maintenance or when performance declines
• Clean all components thoroughly before reassembly
