Description
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 manufacturers guidelines for maintenance intervals
