Graco LD 3:1 Oil Dolly Package, 120 lb Drum, Manual #25C551
This package is built for the shop that does not dispense from one fixed point: the lube truck topping off a fleet in the yard, the mobile mechanic rolling drum and station to the bay door, the small shop where one oil drum has to serve every lift. 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, where the 5:1 pumps trade flow for pressure. The manual meter means the tech reads the dial and stops the flow. The 15 ft hose in the 24H865 kit reaches around a pickup or a class-6 truck without moving the drum.

Questions Shops Ask
What is the difference between the 25C551 and the 25C553?
One cell: the meter. The 25C551 carries the manual meter 25C903; the 25C553 carries the preset meter 256216. 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.
How far does the hose reach?
The included 24H865 kit carries 15 ft of 1/2 in fluid hose - enough to work around a vehicle without rolling the drum; there is no reel on this configuration.

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 downtube, meter, hose kit and dolly base are the matched hardware for the 16 gal (120 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 the loaded dolly. There is no hose reel on this package - the 15 ft hose kit is the reach.
You want the fill to shut itself off - the 25C553 is the identical 3:1 120 lb dolly package with the preset meter 256216. Your drums are 55 gal (400 lb) - the 25C550 (manual meter) and 25C552 (preset meter) are the 3:1 dolly packages built for the larger drum with the drum-length steel downtube 16F886 and the 400 lb drum dolly 129645. You need pressure over flow - the 5:1 dolly packages (25C555, 25C557, 25C554, 25C556) 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.
