Graco LD 3:1 Oil Dolly Package, 400 lb Drum, Preset #25C552
This package is built for the mobile shop that buys oil by the 55 gal drum and has to account for it: the fleet yard charging every quart to a unit number, the lube route whose fill tickets have to match the meter, the truck shop rolling the full-drum station between bays. The preset meter means the tech dials the quantity and the meter stops the fill. The 3:1 ratio is the volume choice of the LD oil line - per the LD Series oil pump specifications, 7.8 gal/min approximate free flow at 100 psi with 450 psi maximum fluid working pressure. The 15 ft hose in the 24H865 kit finishes the reach around the vehicle without rolling the drum.

Questions Shops Ask
What is the difference between the 25C552 and the 25C550?
One cell: the meter. The 25C552 carries the preset meter 256216; the 25C550 carries the manual meter 25C903. Everything else - pump, downtube, hose kit, dolly - is identical.
Why does the regulator have to be ordered separately?
The LD pump's thermal relief function requires a self-relieving air regulator; Graco's table directs you to order regulator 24H420 or filter-regulator 133215 separately rather than bundling it.
What does the preset meter do?
The tech dials the quantity and the meter shuts the fill at the set point - the accountability choice when oil tickets have to match the meter reading.

Fitment & Setup
Compatibility: the pump is the 24G576, Graco's LD Series 3:1 oil pump - 3:1 ratio, 450 psi maximum fluid working pressure, 7.8 gal/min approximate free flow at 100 psi, 1/4 in air inlet and 1/2 in fluid outlet per the LD Series oil pump specifications - and the included drum-length steel downtube, meter, hose kit and dolly base are the matched hardware for the 55 gal (400 lb) drum configuration. Site prep: the oil drum itself, a compressed-air supply (the 3:1 pump operates on 20 to 150 psi) with the separately ordered self-relieving regulator in the line, and floor space to roll a loaded 400 lb drum on its dolly. There is no hose reel on this package - the 15 ft hose kit is the reach.
You want your techs to run the fill by hand - the 25C550 is the identical 3:1 400 lb dolly package with the manual meter 25C903. Your drums are 16 gal (120 lb) - the 25C551 (manual meter) and 25C553 (preset meter) are the 3:1 dolly packages for the smaller drum with the universal cut-to-length PVC downtube 16F878 and the 120 lb drum dolly 131184. You need pressure over flow - the 5:1 dolly packages (25C554, 25C556 for this drum size) run the 24G588 pump at 750 psi. You want the reel-equipped cart format - the mobile cart packages (24H751 series on the 3:1 side) put an LDX hose reel and the 55 gal drum cart 24F915 under the same pump line.
