The Graco Fire-Ball 425 is the pump of choice for demanding high volume applications, suited to fluid oil transfer over longer distances in truck workshops, service fleet facilities, mining, civil construction and in-plant applications where multiple dispense points run at the same time. A large 4.25 inch air motor supplies the power needed for long pipe runs and higher volume dispensing, and the range is offered in 3:1, 6:1 and 10:1 ratios to match the pressure and flow the job demands.
Features
Durable: Thick cast aluminium air motor housing offers strong durability.
Fewer Repairs: Fewer moving parts in the air motor assembly mean less downtime and low repair cost.
Extended Seal Life: The in-line pump design aligns the air motor piston and fluid piston rods to maximise seal life.
Reduce Downtime: Displacement rods have minimal wear thanks to a proprietary Graco manufacturing process.
Superior Sealing: Non-metallic poppet valves seal positively even in contaminated, dirty air environments for long life without repair.
Reduced Icing: A large air porting design uses compressed air efficiently for continuous operation and reduced icing.
Corrosion Resistant: Liquid salt nitriding, nickel plating, stainless steel, aluminium and chrome on key components extend component life.
