GRACO FIRE-BALL 300 STUBBY OIL PUMP
$3,073.40
The Graco Fire-Ball 300 5:1 has been the benchmark in industrial oil pumps for decades. Renowned for its rugged design and long service life, this pump is trusted in heavy-duty environments where uptime and reliability are critical. With fewer moving parts and premium engineering, the Fire-Ball delivers consistent performance, reduced maintenance, and superior productivity.
Ideal for high-pressure, medium-volume oil transfer applications, the Fire-Ball 300 is perfectly suited to automotive dealerships, fast lube centres, fleet maintenance facilities, and service workshops.
Key Features & Benefits
- Reliable Oil Flow – A 76.2 mm (3″) differential air motor combined with a double-acting pump design ensures accurate, continuous fluid delivery.
- Heavy-Duty Durability – Thick cast aluminium air motor housing provides strength and long-lasting performance in demanding environments.
- Low Maintenance Costs – Fewer moving parts mean fewer breakdowns, reduced downtime, and lower repair expenses.
- Extended Seal Life – Precision in-line pump design aligns the air and fluid pistons, maximising seal longevity.
- Proven Reliability – Proprietary Graco manufacturing minimises displacement rod wear for long-term operation.
- Superior Sealing – Non-metallic poppet valves maintain positive sealing, even in dirty air conditions, extending pump life without repair.
- Reduced Icing – Large air porting design optimises compressed air efficiency, enabling continuous operation and minimising icing.
- Corrosion-Resistant Build – Key components treated with liquid salt nitriding, nickel plating, stainless steel, and chrome for maximum protection.
