Description Fire-Ball® 425 Series 10:1 Universal Size Oil Pump Part Number: 205626 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.
