Applications:
Industrial fluid transfer, including antifreeze, detergents, motor oil, hydraulic fluid, cutting oil, water, and wastewater in mining, agriculture, and manufacturing environments[5].

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and compatibility with existing equipment.
• Ensure proper alignment and secure mounting of the pump
• Use recommended air supply pressure (up to 125 psi)
• Check and maintain seals and diaphragms regularly
• Follow manufacturer guidelines for fluid compatibility and maximum solid size
• Inspect air and fluid connections for leaks before operation
• Regularly inspect and replace diaphragms and seals as needed
• Clean pump internals to prevent clogging from solids
• Monitor air consumption and cycle rate for signs of wear
• Use only compatible fluids and avoid exceeding maximum operating temperature
