The GRACO 659040 is a 3-inch aluminum electric diaphragm pump, powered by a 7.5 HP ATEX motor, designed for industrial fluid transfer. It features a robust aluminum construction and is intended for reliable, energy-efficient pumping of a wide range of industrial fluids, including those with solids or abrasives.

Key Features:

• Electric Operated Double Diaphragm (EODD) Pump
• Husky 3300e, 3-inch
• Aluminum center section and body, TPE (thermoplastic elastomer) diaphragms and seats, acetal balls
• Up to 220 gpm
• Designed for industrial fluid transfer, compatible with solids, slurries, and abrasives
• ATEX motor (explosion-proof)
• Up to 80% energy reduction vs. pneumatic pumps
• Runs dry, self-primes, and stalls under pressure
• Seal-less design for reduced maintenance
• Low pulsation without costly dampeners
• Near 0 dB in-plant noise pollution
• Modular design with long-life elastomers
• Accurate fluid metering with VFD controls (optional)
• Robust construction for handling tough transfer jobs

Applications:
Ideal for industrial fluid transfer in environments requiring explosion-proof equipment, including mining, chemical processing, and manufacturing. Suitable for transferring solids, slurries, and abrasive materials without damaging the pump or shearing the material.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety, especially in hazardous environments.
• Install the pump as close as possible to the material source to maximize performance
• Minimize suction requirements for best results
• Use grounded, flexible fluid hoses to reduce static sparking risk
• Install a fluid drain valve near the fluid outlet
• Install a shutoff valve in the fluid outlet line
• Follow torque instructions for inlet/outlet port connections
• Regularly inspect diaphragms and elastomers for wear
• Ensure all connections are secure and leak-free
• Follow manufacturer’s guidelines for maintenance intervals
