The GRACO 189744 PLATE, DIAPHRAGM is a fluid side plate component designed for use in GRACO diaphragm pumps. It is constructed from metal (as indicated by the configuration matrix for certain pump models), and its primary function is to serve as a critical interface between the diaphragm and the fluid chamber, ensuring proper sealing and efficient fluid transfer within the pump assembly.

Key Features:

• Plate, Diaphragm (fluid side)
• 189744
• Compatible with select GRACO QUANTM™ and other industrial diaphragm pump models (see configuration matrix for details)
• Critical sealing interface for diaphragm pumps
• Designed for reliable performance in industrial fluid transfer applications
• Ease of maintenance as part of standard pump service kits

Applications:
Used in industrial diaphragm pumps for transferring a wide range of fluids, including lubricants, chemicals, and other process fluids, across various industries such as mining, agriculture, and manufacturing.

Installation Notes:

• Using genuine GRACO parts ensures optimal pump performance, longevity, and safety. Non-genuine parts may compromise seal integrity and pump reliability.
• Always follow the manufacturer’s instructions for installation and maintenance.
• Inspect the plate and diaphragm for wear or damage before installation.
• Ensure all seals and fasteners are properly seated and tightened to manufacturer specifications.
• Refer to the equipment manual for specific torque values and assembly procedures.
