The Graco Fire-Ball 300 (part number 203876, Series H26R) is a new, USA-made air-powered reciprocating piston pump with a 5:1 pressure ratio, designed for dispensing oil and other lubricants from bulk containers in automotive, fleet, and industrial lube room applications. As read directly from the nameplate label, the pump accepts a maximum air inlet working pressure of 180 psi (12 bar) and delivers a maximum fluid working pressure of 900 psi (62 bar), confirming the 5:1 ratio. The cast iron air motor section is paired with a flanged lower pump section and a steel follower tube; the unit mounts universally to standard drum lids or dispensing systems and ships new-in-box from Graco Inc., Minneapolis, MN, with serial number K507058. The Fire-Ball 300 platform is well-established in lube dispensing systems and is compatible with Graco drum cover kits, hose reels, and control valves designed for the Fire-Ball series.
