The GRACO 650555 is an air-operated double diaphragm pump designed for industrial fluid transfer. It features a PVDF (polyvinylidene fluoride) pump body, PVDF seats, PTFE (polytetrafluoroethylene) balls, and a PO (polyolefin) diaphragm. The pump is intended for handling corrosive or aggressive chemicals and is commonly used in chemical processing, water treatment, and other industrial applications where chemical resistance and reliability are critical.

Key Features:

• Air-operated double diaphragm pump
• Husky 1050
• PVDF pump body, PVDF seats, PTFE balls, PO diaphragm, aluminum center section, IEC 90 gearbox, end flange
• Maximum free flow delivery: 50 gpm (189 lpm)
• Maximum fluid working pressure: 125 psi (8.6 bar, 0.86 MPa); Maximum air pressure: 80 psi (0.55 MPa)
• Designed for use with corrosive and aggressive chemicals; compatible with a wide range of industrial fluids
• Stall-free low pulsation air valve for smooth and rapid changeover
• High chemical resistance due to PVDF and PTFE materials
• Robust construction for demanding industrial environments
• Easy maintenance and serviceability
• Reliable performance with minimal downtime

Applications:
Chemical processing, water treatment, industrial fluid transfer, handling corrosive or aggressive chemicals, and other applications requiring chemical-resistant pumps.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and longevity of the pump. Non-genuine parts may compromise chemical resistance, reliability, and warranty coverage.
• Ensure all connections are secure and leak-free before operation
• Follow GRACO’s recommended installation procedures for air and fluid lines
• Use appropriate gaskets and seals for chemical compatibility
• Regularly inspect and maintain diaphragms, seats, and balls for wear and tear
• Consult the equipment manual for specific installation and maintenance instructions
