Product information

With a large 4.25" (107.9 mm) air motor that delivers the power you need for long pipelines and higher volume dispensing, the Fire-Ball 425 offers field-proven durability for many material 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 fleet maintenance and manufacturing facilities where multiple dispensing operations occur simultaneously.

  • Robust - Unrivalled robust air motor housing made from extremely strong cast aluminium
  • Fewer repairs - Fewer moving parts in the air motor assembly means less downtime and therefore lower repair costs
  • Longer seal life - Inline pump design with aligned air motor pistons and material pistons maximises seal life
  • Less downtime - Graco's unique manufacturing process ensures virtually wear-resistant piston rods
  • Excellent sealing - Plastic disc valves seal positively even in environments with polluted "dirty" air and ensure a long service life with low maintenance requirements
  • Less icing - The large air inlet guarantees efficient utilisation of compressed air for continuous pump operation without icing
  • Corrosion-resistant - Corrosion resistance and long service life of important components thanks to salt bath nitriding, nickel plating, chrome plating and the use of stainless steel and aluminium
