The GRACO 205394 is a heavy-duty pneumatic grease pump designed for high-volume, industrial lubrication applications. It is constructed from robust materials including cast aluminum, steel, brass, and features corrosion-resistant coatings for longevity. This pump is intended for use with grease and is engineered to handle demanding environments, making it suitable for large-scale operations such as mining and agriculture.

Key Features:

• Pneumatic Piston Pump
• Fire-Ball® 425 Series, 120 lb (55 kg) drum capacity
• Cast aluminum air motor housing, steel, brass, aluminum, leather wetted parts, corrosion-resistant coatings (liquid salt nitriding, nickel plating, stainless steel, chrome)
• Maximum flow rate: 0.5 gpm (1.89 l/min)
• Maximum air inlet pressure: 150 psi (10.34 bar, 1034 kPa); Maximum working pressure: 7500 psi (517 bar, 51700 kPa)
• For use with grease; fits 120 lb (16 gallon) drums
• Large air motor for long pipe runs and high-volume dispensing
• Fewer moving parts for reduced downtime and lower repair costs
• Non-metallic poppet valves for superior sealing in dirty air environments
• In-line pump design maximizes seal life
• Corrosion-resistant construction for extended service life
• Durable, thick cast aluminum housing

Applications:
Ideal for industrial lubrication systems requiring high-volume grease dispensing, such as in mining, agriculture, manufacturing, and vehicle service centers. Suitable for environments where multiple dispenses occur simultaneously and where long pipe runs are required.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and compatibility with existing systems. Non-genuine parts may compromise safety and efficiency.
• Ensure the pump is mounted securely to a stable surface
• Connect air supply within the specified pressure range (40–150 psi)
• Use appropriate fittings and hoses rated for the maximum working pressure
• Regularly inspect seals and moving parts for wear and replace as needed
• Follow all safety guidelines and manufacturer recommendations during installation and maintenance
