Fire-Ball 425 Pumps

The Fire-Ball 425 is perfect for fluid oil transfer in high volume and longer distance applications such as truck shop service fleet facilities and in-plant applications.

  • Corrosion-resistant design utilizes liquid salt nitriding, nickel plating, stainless steel, aluminum and chrome on key components for longer life
  • Few moving parts in the air motor assembly means less downtime and low repair cost
  • Displacement rods have minimal wear due to a proprietary Graco manufacturing process
  • Large air porting design provides efficient use of compressed air supply for continuous pump operation without icing
