The GRACO 652411 is a double diaphragm pump featuring a polypropylene center section and body, with stainless steel seats. It is designed for transferring a wide range of fluids in industrial applications, offering chemical resistance and durability for demanding environments.

Key Features:

• Air-operated double diaphragm pump
• Husky 3300, 3" (76.2 mm) flange
• Polypropylene center section and body, stainless steel seats, santoprene diaphragms and balls, PTFE manifold and seat seals
• Up to 300 GPM (1,135 LPM)
• Compatible with a wide range of industrial fluids, especially those requiring chemical resistance
• Four-bolt joint design for even sealing and leak-free operation
• Modular, stall-resistant air valve for smooth and rapid changeover
• One-piece center section reduces leaks and maintenance
• Heavy-duty construction for long service life
• Ease of maintenance and faster changeover with spring-loaded pilot valves
• Up to 5 times longer diaphragm life compared to other air-operated diaphragm pumps

Applications:
Ideal for transferring chemicals, solvents, and other aggressive fluids in industries such as mining, agriculture, manufacturing, and wastewater treatment. Suitable for applications requiring chemical resistance and high flow rates.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety. Non-genuine parts may compromise pump integrity and void warranties.
• Install the pump as close as possible to the material source to minimize suction requirements and maximize performance
• Use grounded, flexible fluid hoses to reduce the risk of static sparking
• Install a fluid drain valve near the fluid outlet and a shutoff valve in the fluid outlet line
• Follow torque instructions for manifold installation to prevent leaks
• Ensure the equipment is properly grounded to reduce static sparking risks
• Regularly inspect diaphragms, seats, and seals for wear
• Replace worn components with genuine GRACO parts
• Keep the pump clean and free from debris
• Follow manufacturer-recommended maintenance intervals
