The GRACO 187716 is a diaphragm component designed for use in GRACO air-operated diaphragm pumps. It is a critical wear part that separates the air and fluid sections of the pump, ensuring reliable and leak-free operation. The material is not explicitly stated in available documentation, but similar GRACO diaphragms are typically made from elastomeric materials such as Buna-N or PTFE for chemical resistance and durability.

Key Features:

• Diaphragm
• Elastomeric (likely Buna-N or PTFE, based on similar parts)
• Compatible with GRACO air-operated diaphragm pumps (e.g., Herkules 338 series)
• Designed for reliable, leak-free separation of air and fluid sections
• Engineered for chemical resistance and long service life
• Easily replaceable for maintenance

Applications:
Used in GRACO air-operated diaphragm pumps for transferring a wide range of fluids in industrial, agricultural, and maintenance applications.

Installation Notes:

• Using genuine GRACO diaphragms ensures optimal pump performance, safety, and longevity. Non-genuine parts may compromise reliability and void warranties.
• Always follow the manufacturer’s instructions for diaphragm replacement
• Ensure the pump is depressurized and isolated from fluid and air sources before servicing
• Inspect related components (O-rings, seals) for wear and replace if necessary
• Use appropriate tools and safety equipment during installation
