Graco Fire-Ball 300 5:1 Oil Pump, 55 Gal Drum, Cover Mount #203857
Graco's Fire-Ball 300 5:1 oil pump is the industry's mainstay lubrication pump, built with fewer moving parts to extend uptime and lower repair costs. A 3 in. differential air motor drives a double-acting piston design for reliable, accurate dispense in high-pressure, medium-volume oil transfer applications like automotive dealerships, fast lube centers, and fleet service shops.
The 203857 is configured for a 55 gal. (400 lb) drum with cover mount - it installs through a standard drum cover rather than the drum's bung opening. Non-metallic poppet valves keep sealing tight even with contaminated shop air, and corrosion-resistant plating on key components extends service life well beyond typical pump designs.

Compatibility & Fitment
Sized for a standard 55 gal. (400 lb) drum with cover mount installation (not a bung-mount drum - see the 204254 for the bung-mount version of this same pump). 3/8 in. NPT female air inlet requires a regulated shop air line up to 180 psi max. 1-1/2 in. NPT female fluid inlet draws from the drum; 1/2 in. NPT female fluid outlet connects to your dispense hose and valve (ordered separately). A 2 in. NPT bung adapter is available separately if you need to convert a bung-style drum to accept this cover-mount pump.
Warranty
Graco backs this equipment with its standard 1-year warranty against defects in material and workmanship from the date of sale.
