Fire-Ball 425 high-volume oil pump designed for demanding environments requiring continuous duty operation. Built with durable, non-corrosive air motor design featuring stainless steel, aluminum and chrome metal parts for long life. Double-acting pump provides reliable fluid flow with no metal-to-metal contact, ensuring the pump withstands harsh environments while reducing downtime and maintenance costs.
With a large 4.25 inch (107.9 mm) air motor to supply the power you need for long pipe runs and higher volume dispensing, the Fire-Ball 425 delivers field-proven durability for multiple fluid types and exceptional cost savings that are hard to beat!
The Fire-Ball 425 is the pump of choice for your most demanding high volume applications – an ideal choice for applications such as truck fleet service facilities and in-plant applications where multiple dispenses happen at the same time.
Durable – Thick cast aluminum air motor housing offers unmatched durability.
Fewer Repairs – Fewer moving parts in the air motor assembly means less downtime and low repair cost.
Extended Seal Life – In-line pump design aligns the air motor piston and fluid piston rods to maximize seal life.
Reduce Downtime – Displacement rods have minimal wear due to a proprietary Graco manufacturing process.
Superior Sealing – Non-metallic poppet valves offer positive sealing performance, even with contaminated “dirty” air environments for long life without repair.
Reduced Icing – Large air porting design provides efficient use of compressed air supply for continuous pump operation and reduced icing.
Corrosion-Resistant – Corrosion-resistant design utilizes liquid salt nitriding, nickel plating, stainless steel, aluminum and chrome on key components for longer life.
