Graco LD 50:1 Grease Package, 120 lb Drum, Mobile #25C548
This package is built for the shop that greases in drum quantities and away from the wall: the fleet shop rolling a 120 lb drum of chassis grease out to the yard, the lube truck whose grease supply is a drum, the service bay that wants drum-side grease with the whole station on wheels. Per the catalog's LD Series 50:1 pump pages, this line is built for lower-volume applications - up to 7,000 lb (3,175 kg) of grease per year - with typical applications in automotive dealerships, fast lube centers, service shops and lube trucks, and typical fluids up to NLGI #2 grease. The 50:1 ratio delivers 7,500 psi of working pressure through a 3 in air motor; the follower plate wipes the drum so the pump keeps priming as the level drops; the dolly base makes the full drum portable.

Questions Shops Ask
What is the difference between the 25C548 and the 26C170?
The 25C548 is the mobile dolly package with the 24H862 6 ft hose kit and portable base; the 26C170 is the stationary kit with fitting 157705, air regulator 24H420 and air filter 106148, and a 30 in whip with a 1/4 in x 3/8 in x 20 ft grease hose. Same pump, same 120 lb drum format, different mounting intent.
What is the difference between the 25C548 and the 25N618?
Both are mobile 120 lb packages, but the 25C548 carries the 6 ft 24H862 hose kit with no regulator, while the 25N618 carries a 1/4 in ID x 12 ft grease hose with fittings 165198/169970 and air regulator 24H420 - longer reach, bundled regulator.
Will it pump NLGI #2 grease?
Yes - NLGI #2 is the catalog's stated typical fluid ceiling for the LD Series 50:1 grease line.

Fitment & Setup
Compatibility: the pump is the 24G603, Graco's LD Series 50:1 grease pump for 120 lb drums - per the LD Series 50:1 pump specifications, 50:1 fluid pressure ratio, 3 in (76.2 mm) air motor effective diameter, 7,500 psi (517 bar) maximum fluid working pressure, 4.5 lb/min (2 kg/min) approximate free flow at 100 psi, 1/4 in NPT(F) air inlet and 1/4 in NPT(F) fluid outlet, 20 to 150 psi air operation - and the follower plate, cover, hose kit, valve, swivel and dolly are the matched hardware for the 120 lb drum configuration. Site prep: the grease drum itself, a compressed-air supply (the pump operates on 20 to 150 psi), and floor space to roll the loaded drum on its dolly. This mobile configuration has no hose reel - the 6 ft hose kit plus the grease valve is the reach.
Your grease comes in 35 lb (16 kg) pails - the 25C549 is the same mobile package built for the pail with pump 24G600, follower plate 24F901, cover 24F904 and the 35 lb drum dolly 131183. Your grease comes in 400 lb (180 kg) drums - the mobile 400 lb packages in the 400 lb table (24J054, 24J066) run pump 24G606 with the drum cart 24F915. You want the stationary drum-side kit with the air regulator and air filter - the 26C170 adds fitting 157705, air regulator 24H420 and air filter 106148, and carries a 30 in whip with a 20 ft grease hose. You want the 12 ft hose with the regulator bundled - the 25N618 in the same table carries a 1/4 in ID x 12 ft grease hose, fittings 165198/169970 and air regulator 24H420.
