Description

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.
