The Graco Fire-Ball 425 Air-Operated Pump is designed for high-volume fluid transfer applications requiring long-distance delivery and reliable performance.
It is commonly used in truck shops, fleet service facilities, and in-plant maintenance environments where multiple dispense points operate simultaneously.
Built for High-Volume Lubrication and Oil Transfer Applications
The Fire-Ball 425 is engineered for demanding lubrication systems where consistent flow, durability, and long service life are required.
It is suitable for:
High-volume oil transfer.
Fleet maintenance systems.
Industrial lubrication networks.
Multi-dispense point applications.
Features of the Graco Fire-Ball 425 Pump
Corrosion-Resistant Construction
Uses liquid salt nitriding, nickel plating, stainless steel, aluminium, and chrome on key components to extend service life.
Reduced Maintenance Design
Fewer moving parts in the air motor assembly help reduce downtime and lower repair costs.
Long-Life Displacement Rods
Proprietary Graco manufacturing processes reduce wear on displacement rods.
Efficient Air Usage
Large air porting design supports continuous operation and helps reduce icing during use.
