The GRACO 659806 is a 3-inch stainless steel electric diaphragm pump designed for heavy-duty industrial fluid transfer. It features a 7.5 Hp AC motor, end port BSP connections, an aluminum center section, and Geolast (GE) seat, ball, and diaphragm components. This pump is engineered for reliable, efficient transfer of a wide range of industrial fluids, including those with solids, slurries, and abrasives.

Key Features:

• Electric Operated Double Diaphragm (EODD) Pump
• Husky 3300e, 3-inch
• Stainless steel wetted parts, aluminum center section, Geolast (GE) seat, ball, and diaphragm
• Up to 220 gpm
• Designed for use with a wide range of industrial fluids, including solids, slurries, and abrasives
• Up to 80% reduction in energy usage compared to air diaphragm pumps
• Runs dry, self-primes, and stalls under pressure
• Seal-less design for reduced maintenance
• Modular design with long-life elastomers
• Low pulsation without costly dampeners
• Near 0 dB in-plant noise pollution
• Accurate fluid metering with VFD controls (where applicable)
• Pump replacables last up to 5x longer compared to other brands

Applications:
Ideal for tough transfer jobs in industries such as mining, agriculture, chemical processing, and manufacturing. Suitable for transferring fluids with solids, slurries, and abrasives without damaging the pump or shearing the material.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety. Non-genuine parts may compromise pump efficiency and longevity.
• Ensure all connections are secure and compatible with BSP end port specifications
• Follow manufacturer guidelines for electrical and mechanical installation
• Verify proper alignment and support for the pump and motor assembly
• Check for correct diaphragm, seat, and ball installation before operation
• Perform initial priming and test run to confirm proper function
• Regularly inspect and replace wear parts such as diaphragms, seats, and balls as needed
• Monitor for leaks and unusual noise during operation
• Keep the pump and surrounding area clean to prevent contamination
• Consult the equipment manual for detailed maintenance schedules and procedures
