GRACO 238108 – Fire-Ball 425, 6 1 Universal Oil Pump, 1100 PSI

GRACO 238108 – Fire-Ball 425 Series 6:1 Universal Size Oil Pump, 1100 PSI

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.
