5-Gallon Bucket Pumps
A 5-gallon bucket pump moves grease straight out of the pail it ships in — no decanting, no scooping, no air pockets in the grease. Bolt the pump onto the pail lid, connect drive or start stroking, and grease flows through a hose to the fitting. For workshops, fleets, and maintenance carts, it is the cheapest lubrication station that exists.
Six pumps are listed here: air-operated and electric grease units, the manual pail pump with follower plate, two fluid-transfer models for oils, and the 9120 air drum pump for the 120 lb drum one size up. The wider station range — 55-gallon drums and lift systems — sits in the grease dispenser category.
Choosing a 5-Gallon Bucket Pump
| Selection factor | What to check |
|---|---|
| Drive | Shop air: pneumatic, most output. No air: electric bucket pump. Nothing available: manual lever — slowest but indestructible. |
| Media | Grease pumps are built for NLGI 2 in 25–50 lb pails; oil and fluids transfer through the fluid-transfer models — keep each to its media. |
| Follower plate | A plate that descends with the grease level keeps air out and priming intact through the whole pail — standard on the manual unit, worth specifying on any high-use station. |
| Hose and coupler | Check included hose length and coupler type against your fittings before ordering; long runs eat pressure on manual units. |
| Duty | A few pails a year: manual. Daily workshop greasing: air or electric. Mobile service truck: electric on a bucket bracket. |

5-Gallon Bucket Pump FAQs
Will these fit a standard 5-gallon pail?
Yes — all pail-mount models here fit standard 5-gallon buckets as shipped by grease manufacturers (25–50 lb of NLGI 2). The 9120 is the exception: it is sized for 120 lb drums, listed here as the next container size up.
Air, electric, or manual — which bucket pump?
Shop air at the bench: the pneumatic pump delivers the most grease per dollar of equipment. No air line: the electric bucket pump. Infrequent use or field work without power: the manual lever pump — stroke effort is the price of total independence.
What does the follower plate actually do?
As grease is pumped out, the plate slides down the pail and stays seated on the grease surface. That seals the top, keeps air from channeling into the pump, and lets you use the entire pail without re-priming — which is why it is standard on the manual unit and recommended for any daily-use station.
Can I pump oil with a grease bucket pump?
Not well — grease pumps are high-ratio and slow-moving by design. For oils and fluids use the electric transfer models listed here, which self-prime and move liters per minute; grease and fluid duties each have their proper pump.
What if I need more than a pail can hold?
Move up in container size: the 9120 handles 120 lb drums, and the grease dispenser category covers 55-gallon systems and 200 L lift stations. Portable hand options for small jobs sit in the hand pump category.
