• Compatible with a wide range of fluids due to expanded material offerings; suitable for use with various GRACO equipment and industrial systems
• Offered in ATEX configuration for hazardous environments (not all models; check specific part number for certification)
• 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
• Overall improved efficiency (up to 40% more efficient)
• Highest fluid flow rate in its class

Applications:
Industrial fluid transfer, chemical processing, mining, agriculture, and other demanding environments requiring robust, efficient, and reliable pumping solutions.

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/outlet port connections
• Ground the system to reduce static sparking risk
• Regularly inspect diaphragms and valves for wear
• Ensure proper grounding and hose connections
• Follow manufacturer’s maintenance schedule and guidelines
