Applications:
Ideal for fluid transfer in industries such as mining, agriculture, chemical processing, and general industrial applications where robust, reliable, and portable pumping is required.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and longevity of the pump.
• Install an air regulator and gauge to control fluid pressure
• Use a minimum 1/2 inch (13 mm) ID electrically conductive air hose
• Install bleed-type master air valves close to the pump and upstream from accessories
• Ensure the air-line filter is installed to remove dirt and moisture from the compressed air supply
• Ground the entire fluid system when pumping conductive flammable fluids
• Regularly inspect and service the air valve and ball checks
• Monitor air supply for contaminants and moisture
• Follow manufacturer guidelines for diaphragm and seal replacement
