The GRACO 197648 is a replacement diaphragm for GRACO air-operated diaphragm pumps. The specific material is not detailed in available sources, but GRACO diaphragms are commonly made from TPE (thermoplastic polyester elastomer), rubber, or other elastomers depending on the pump model. This part is intended to maintain the sealing and pumping function within GRACO diaphragm pump assemblies, ensuring reliable fluid transfer in lubrication and maintenance systems.

Key Features:

• Diaphragm (pump component)
• Designed for use in GRACO air-operated diaphragm pumps; check pump model for exact fit
• Essential for maintaining pump integrity and preventing leaks
• Designed for easy replacement and maintenance
• Supports reliable, continuous operation in demanding environments

Applications:
Used in GRACO air-operated diaphragm pumps for transferring fluids such as lubricants, fuels, and other compatible liquids in industrial, mining, and agricultural settings.

Installation Notes:

• Using genuine GRACO diaphragms ensures optimal performance, safety, and longevity of the pump. Non-genuine parts may compromise system reliability and void warranties.
• Always follow the pump manufacturer’s instructions for diaphragm replacement
• Inspect the diaphragm and related seals for wear or damage before installation
• Ensure the pump is depressurized and isolated from the system before servicing
• Use appropriate tools and safety equipment during installation
• Regularly inspect diaphragms for signs of wear or fatigue
• Replace diaphragms as part of routine maintenance to prevent unexpected downtime
• Keep spare diaphragms on hand for critical applications
