The GRACO 659038 HUSKY PUMP, 3300A-E A04CA2SSPTPTPT is a heavy-duty, 3-inch aluminum electric diaphragm pump designed for high-efficiency fluid transfer in demanding industrial environments. It features PTFE diaphragms and is intended for use in applications requiring reliable, high-volume pumping of various fluids, including those with high viscosity or containing solids.

Key Features:

• Electric diaphragm pump
• 3300A-E, 3-inch (76.2 mm) connection
• Aluminum center section with PTFE diaphragms
• Up to 300 gpm (1,135 lpm)
• Maximum working pressure: 125 psi (0.86 MPa, 8.6 bar) for aluminum center section
• Compatible with a wide range of fluids, including high-viscosity and solids-containing materials
• ATEX induction motor available (for hazardous environments)
• Stall-free low pulsation air valve for smooth operation
• One-piece center section eliminates leaks and reduces maintenance
• Up to 5 times longer diaphragm life compared to other air-operated diaphragm pumps
• Modular stall-resistant air valve design
• Heavy-duty construction for reliability and long service life
• High-speed gear ratio for improved efficiency

Applications:
Ideal for industrial fluid transfer, including mining, agriculture, chemical processing, and bulk material handling. Suitable for pumping high-viscosity fluids and those containing solids up to 1/2 inch (13 mm) in size.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and longevity of the pump. Non-genuine parts may compromise reliability and void warranties.
• Ensure proper alignment and secure mounting to prevent vibration and leaks
• Use appropriate fittings and hoses rated for the intended pressure and fluid
• Follow all safety instructions and local regulations during installation
• Regularly inspect diaphragms and seals for wear and replace as needed
• Consult the manual for specific wiring and electrical requirements for electric models
• Perform routine inspections of diaphragms, seals, and valves
• Keep the pump clean and free from debris
• Lubricate moving parts as recommended by the manufacturer
• Monitor for leaks and unusual noises during operation
