The GRACO Fire-Ball® 425 Series 50:1 400 lb. (181 kg) Grease Pump is a robust, industrial-grade piston pump designed for stationary supply applications. It is constructed with cast steel (CS) and leather components, engineered for reliable, high-volume grease dispensing in demanding environments.

Key Features:

• Piston Pump Package
• Series 425, 50:1 ratio, 400 lb. (181 kg) capacity
• Cast steel (CS), leather
• Maximum air working pressure: 150 psi (1.03 MPa); Maximum working pressure: 27.6 MPa
• Industrial grease
• Large air motor for high power and long pipe runs
• Durable cast aluminum air motor housing
• Fewer moving parts for reduced downtime and repair costs
• Superior sealing with non-metallic poppet valves for long life in dirty air environments
• Extended seal life due to in-line pump design
• Corrosion-resistant design with liquid salt nitriding, nickel plating, stainless steel, aluminum, and chrome on key components

Applications:
Ideal for high-volume, industrial grease dispensing applications, especially where multiple dispenses occur simultaneously or long pipe runs are required. Suitable for use in mining, agriculture, and other heavy-duty environments.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and compatibility with existing equipment.
• Ensure proper alignment of air motor piston and fluid piston rods for maximum seal life
• Use recommended air pressure (up to 150 psi) for safe and efficient operation
• Regularly inspect and maintain seals and valves to prevent contamination and ensure longevity
• Follow all safety guidelines and manufacturer recommendations during installation and maintenance
