The GRACO 238108 is a robust, air-operated piston oil pump designed for high-volume fluid transfer in demanding industrial environments. It features a large 4.25-inch air motor and is constructed from corrosion-resistant materials including aluminum, steel, polyurethane, and nitrile. This pump is intended for use in applications requiring reliable, high-volume oil dispensing, such as truck fleet service facilities and in-plant operations where multiple dispense points are needed.

Key Features:

• Air-operated piston oil pump
• Fire-Ball® 425 Series, 6:1 ratio
• Corrosion-resistant: liquid salt nitriding, nickel plating, stainless steel, aluminum, chrome on key components; wetted parts: aluminum, steel, polyurethane, nitrile
• Approx. 69 liters per minute (LPM) at 100 psi air; also listed as 6 gallons per minute (GPM)
• Maximum fluid pressure: 1100 PSI; Air operating range: 40–180 PSI
• Universal size for multiple fluid types; suitable for long pipe runs and high-volume dispensing
• Durable cast aluminum air motor housing
• Fewer moving parts for less downtime and low repair cost
• In-line pump design maximizes seal life
• Non-metallic poppet valves for positive sealing, even with contaminated air
• Large air porting for efficient compressed air use and reduced icing
• Extended seal life and minimal wear on displacement rods

Applications:
Ideal for high-volume oil transfer in truck fleet service facilities, in-plant operations, and other industrial settings requiring multiple simultaneous dispense points and long pipe runs.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and longevity of the pump, as well as compatibility with GRACO equipment and systems.
• Ensure proper alignment of air and fluid connections
• Use recommended air supply pressure (40–180 PSI)
• Follow manufacturer guidelines for maintenance intervals
• Inspect seals and wetted parts regularly for wear and contamination
• Use only compatible fluids as specified by GRACO
• Regularly check for air leaks and proper lubrication
• Monitor pump cycles and avoid exceeding maximum recommended speed
• Keep air supply clean and dry to prevent contamination and icing
• Replace worn seals and components with genuine GRACO parts
