The GRACO 656399 is an electric diaphragm pump featuring a PVDF (polyvinylidene fluoride) fluid section and an aluminium centre section. It is designed for reliable, efficient transfer of aggressive chemicals and fluids in demanding industrial environments.

Key Features:

• Electric diaphragm pump
• Husky 2150F-E, 2" (51 mm) ANSI end-porting
• PVDF fluid section, aluminium centre section, Santoprene seats
• Designed for use with aggressive chemicals and fluids; compatible with GRACO Husky 2150 series equipment
• Durable PVDF construction for chemical resistance
• Aluminium centre section for strength and corrosion resistance
• Santoprene seats for reliable sealing
• Designed for ease of maintenance and reliability
• Externally accessible air valve (on air-operated models; not directly applicable to electric version, but similar design philosophy may apply)

Applications:
Ideal for transferring aggressive chemicals, acids, and solvents in industries such as chemical processing, mining, agriculture, and manufacturing. Suitable for applications requiring robust, corrosion-resistant pumping solutions.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and compatibility with existing equipment. Non-genuine parts may compromise safety and efficiency.
• Ensure all connections are secure and compatible with the pump’s material and chemical resistance requirements
• Follow manufacturer guidelines for electrical and fluid connections
• Regularly inspect seals and seats for wear and replace as needed
• Consult the equipment manual for specific installation and maintenance procedures
