Graco Fire-Ball 300 50:1 Grease Pump, 400 lb Drum #239888
Graco's Fire-Ball 300 50:1 grease pump is built for high-pressure, high-viscosity grease applications where a 5:1 or 15:1 pump can't keep up. A 3 in. differential air motor and double-acting piston design deliver up to 8,400 psi of fluid pressure - well suited to long hose runs, cold grease, or heavy-duty undercarriage lubrication in fleet and service shops.
The 239888 mounts on a full 400 lb. (180 kg) drum, matching the highest-volume application in this pump family, and ships as a bare pump that pairs with a separately ordered dispense valve and hose. Non-metallic poppet valves resist wear even with contaminated shop air, and corrosion-resistant plating extends service life.
