The GRACO 652856 is a stainless steel (SS) air-operated double diaphragm pump with a polypropylene (PP) center section, designed for high-volume fluid transfer in industrial applications. It is intended for use within GRACO equipment to handle a wide range of fluids, including those requiring chemical resistance and high flow rates.

Key Features:

• Air-operated double diaphragm pump
• Husky 3300, 3 in. BSPT
• Stainless steel (SS) pump with polypropylene (PP) center section, PTFE diaphragm and balls
• Up to 280–300 GPM (varies by configuration)
• Maximum fluid pressure: 0.7 MPa
• Compatible with a wide range of industrial fluids, especially those requiring chemical resistance
• CE (varies by configuration), ATEX available
• Stall-free low pulsation air valve for smooth and rapid changeover
• 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
• Expanded material offering for handling numerous applications

Applications:
Ideal for high-volume fluid transfer in industries such as mining, agriculture, chemical processing, and manufacturing. Suitable for handling abrasive, corrosive, or viscous fluids.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety. Non-genuine parts may compromise pump efficiency and longevity.
• 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 inlet and outlet port connections
• Ensure the equipment is properly grounded
