Product information

With a large 4.25" (107.9 mm) air motor that delivers the power you need for long pipe and larger volume dispensing, the Fire-Ball 425 offers field-proven durability on many types of materials 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 fleet and manufacturing equipment maintenance where multiple dispensing operations are performed in succession.

  • Rugged – Unsurpassed rugged air motor housing made of extremely strong cast aluminium
  • Fewer repairs – Fewer moving parts in the air motor assembly means less downtime and lower repair costs
  • Extended seal life – In-line pump design with aligned air motor and fluid pistons maximises seal life
  • Less downtime – Graco's unique manufacturing process ensures that piston rods are virtually wear-resistant
  • Excellent sealing – plastic poppet valves provide a tight seal even in environments with contaminated "dirty" air, and ensure a long service life with little maintenance
  • Reduced icing – large air inlet ensures efficient use of compressed air for continuous pump operation without icing
  • Corrosion resistant – corrosion resistance and long service life of important components through salt bath nitriding, nickel plating, chrome plating and the use of stainless steel and aluminium
