The GRACO 649577 is an air-operated diaphragm pump featuring a center flange and a 1" fluid outlet. Its fluid section is constructed from PVDF (Kynar), with a polypropylene (PP) center section, PVDF seats, PTFE balls, and an SP diaphragm. It is designed for reliable, chemical-resistant fluid transfer in industrial applications.

Key Features:

• Air-operated diaphragm pump
• Husky 1050, 1" outlet
• PVDF (Kynar) fluid section, PP center section, PVDF seats, PTFE balls, SP diaphragm
• Designed for use with compatible GRACO Husky 1050 pump systems
• Stall-free, low pulsation air valve for smooth and rapid changeover
