Graco Fire-Ball 425 50:1 Grease Pump, 400 lb Stationary RAM Package #244905
The Graco #244905 is the Fire-Ball 425 50:1 stationary RAM package for 400 lb (180 kg) drums — the forced-feed bulk system for the hardest greases in the room. The RAM (assembly 257435) drives the follower plate down the drum under air pressure, force-feeding the pump instead of letting gravity and pump suction do the work: Graco's own bullets for the RAM packages are extreme-viscous grease, reduced waste, high-volume pumping, and clean drum changes. For hard NLGI #2 service, cold rooms, and greases that channel and bridge under a plain follower plate, this is the configuration that keeps the pump fed.
On the numbers, stated explicitly for this package in manual 309345H: 4,000 psi (276 bar) maximum fluid working pressure at 80 psi maximum air. Behind it sits the 50:1 Fire-Ball 425 — 9 lb/min free flow, 3.35 lb/min continuous duty, 4.25 in. air motor, up to 7,500 psi of pump fluid working pressure. The package arrives as a system: pump 205395, ram 257435, adapter kit 224266, ram plate seal kit 247335, pump mount kit 247337 and the 222076 dispense kit; the air gauge comes with the RAM controller per the catalog's footnote for this package.
What the Package Includes
- Fire-Ball 425 50:1 pump 205395 (400 lb drum pump)
- Ram assembly 257435, adapter kit 224266, ram plate seal kit 247335, pump mount kit 247337
- Dispense kit 222076 (4,000 psi): 3/8 in. × 6 ft fluid hose (109163), 6 ft coupled hose (205418), fittings 155470/155494, 1/2 in. × 6 ft air hose
- Air gauge included with the RAM controller per the catalog's footnote for this package
Not the Right Package If
- You want the 75:1 RAM — that is 244906 (pump 239730)
- Your grease flows fine under a plain follower plate — the stationary supply package 225781 is the simpler system at a simpler price
- You prefer an inductor-plate system over a ram — the topper-inductor package is 226018
- The drum rides in a truck — RAM packages are stationary; the 50:1 lube truck package is 222075
Questions Shops Ask
Why a RAM at all?
For extreme-viscosity grease and high-volume service. The ram force-feeds the follower plate down the drum — no channeling, no bridging, no starved pump — and Graco lists cleaner drum changes as a RAM benefit. If your current follower-plate setup starves on cold NLGI #2, this is the fix.
50:1 or 75:1 RAM — which one?
Both are 4,000 psi packages on the same ram 257435. The 50:1 moves more grease per minute (9 lb/min free flow vs 6.5); the 75:1 gives more cycles per pound (22.7 vs 15.1) and runs a 53 psi air limit against this package's 80 psi. Flow needs decide.
What air supply does it need?
A 1/2 in. NPT(F) inlet. Manual 309345H caps this package at 80 psi max air — 50:1 × 80 psi equals the kit's 4,000 psi rating. The draft's 150 psi figure was the pump's air-range top, not the package limit.
