Applications:
Industrial fluid transfer, including antifreeze, detergents, resins, polymers, oils, hydraulic and transmission fluids, cutting oil, water, wastewater treatment, and ink

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety, and maintains warranty coverage.
• Ensure the pump is properly grounded when pumping conductive flammable fluids, as polypropylene and PVDF models are not conductive
• Follow all safety instructions in the manual
• Use appropriate fittings and hoses for the intended application
• Regularly inspect and maintain the pump for leaks and wear
• Regularly check and clean ball checks and air valve
• Inspect diaphragms and seats for wear and replace as needed
• Use only compatible fluids as specified in the manual
