The GRACO 246775 Mini Fire-Ball® 225 3:1 Universal Size Oil Pump is a compact, pneumatic piston pump designed for medium-pressure, low-volume oil transfer applications. It is constructed with corrosion-resistant materials including cast aluminum, stainless steel, nickel plating, and chrome on key components. This pump is intended for use with petroleum- and synthetic-based oils (motor, gear, and ATF) within GRACO lubrication equipment.

Key Features:

• Pneumatic Piston Pump
• Mini Fire-Ball 225, 3:1 Universal Size
• Cast aluminum air motor housing, stainless steel, nickel plating, chrome on key components
• Free flow rate @ 100 psi: 8.3 gpm (32 L/min)
• Maximum working pressure: 540 psi (37 bar / 3.7 MPa)
• Petroleum- and synthetic-based oils (motor, gear, and ATF)
• Durable, thick cast aluminum air motor housing
• Fewer moving parts for less wear and reduced downtime
• Extended seal life due to in-line pump design
• Minimal wear on displacement rods (proprietary GRACO process)
• Non-metallic poppet valves for superior sealing, even with contaminated air
• Large air porting for efficient compressed air use and reduced icing
• Corrosion-resistant design for longer life

Applications:
Medium-pressure, low-volume oil transfer in automotive, industrial, and maintenance environments. Suitable for use with motor, gear, and automatic transmission fluids.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and compatibility with GRACO equipment.
• Ensure compressed air supply meets maximum air inlet pressure (180 psi) and consumption (20 SCFM) requirements
• Check compatibility with intended oil type before installation
• Follow manufacturer guidelines for hose and line installation (supports line lengths up to 250 ft)
• Regularly inspect seals and moving parts for wear and contamination
• Use only recommended oils and fluids
• Maintain clean air supply to prevent contamination
• Perform routine maintenance as per equipment manual
• Replace worn or damaged parts with genuine GRACO components
