The GRACO 189536 is a diaphragm made from Santoprene material, designed for use in GRACO 515 series air-operated double diaphragm (AODD) pumps. It serves as a critical sealing and flexing component within the pump, enabling the transfer of fluids while maintaining separation between the air and fluid chambers.

Key Features:

• Diaphragm
• 515, AODD
• Santoprene
• GRACO 515 series AODD pumps
• Durable Santoprene construction for chemical resistance and flexibility
• Designed for reliable operation in demanding industrial environments
• Ease of maintenance and replacement

Applications:
Used in industrial fluid transfer applications, including lubrication, chemical processing, and maintenance operations where reliable, chemical-resistant diaphragm performance is required.

Installation Notes:

• Using genuine GRACO diaphragms ensures optimal pump performance, longevity, and safety. Non-genuine parts may not meet the same quality or compatibility standards.
• Ensure the pump is depressurized and isolated from the system before installation
• Inspect the diaphragm for any defects prior to installation
• Follow the manufacturer’s recommended installation procedure for the specific pump model
• Regularly inspect and replace diaphragms as part of routine maintenance to prevent leaks and downtime
