The GRACO 189309 is a diaphragm plate, typically constructed from a durable material (exact material not specified in available sources), designed for use as a fluid side plate in GRACO diaphragm pumps. Its primary function is to support and secure the diaphragm within the pump assembly, ensuring proper fluid transfer and pump reliability.

Key Features:

• Plate, Diaphragm
• Compatible with select GRACO diaphragm pumps (e.g., QUANTM™ Industrial Models such as i30 (QTC), i80 (QTD), i120 (QTE))
• Supports diaphragm for reliable pump operation
• Engineered for ease of maintenance and replacement
• Designed for professional industrial use

Applications:
Used in industrial fluid transfer applications, particularly in GRACO diaphragm pumps for reliable and efficient fluid handling. Not for use with hygienic (sanitary) applications or gasoline.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and longevity of the pump system.
• Refer to the specific GRACO pump manual for detailed installation instructions
• Ensure all components are clean and free of debris before assembly
• Use appropriate tools and follow torque specifications for secure installation
• Inspect diaphragm and plate for wear or damage during maintenance
