The GRACO 649388 is a center flange for the Husky 1050 PVDF air-operated double diaphragm pump. It is constructed from PVDF (polyvinylidene fluoride), a highly chemical-resistant thermoplastic, and is designed to provide a secure connection and reliable flow path within the pump assembly. This part is intended for use in industrial fluid transfer applications where chemical compatibility and durability are required.

Key Features:

• Pump center flange
• Husky 1050 PVDF
• PVDF (polyvinylidene fluoride)
• GRACO Husky 1050 series pumps
• Chemical-resistant PVDF material
• Center flange design for secure pump assembly
• Durable construction for industrial environments

Applications:
Industrial fluid transfer, chemical processing, and applications requiring chemical-resistant pump components.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of the pump system.
• Ensure the pump is depressurized and isolated from the system before installation.
• Inspect the flange and mating surfaces for damage or contamination.
• Follow GRACO’s recommended torque specifications for flange bolts.
• Use appropriate gaskets and seals as specified in the manual.
