What a 24V Portable Grease Pump Does
A 24V portable grease pump is a powered lubrication tool you carry to the machine instead of plumbing the machine to a pump. It draws grease from its own reservoir and delivers it through a hose at 10,000 to 12,000 PSI, depending on the model, so it can push NLGI #2 grease into pins, bushings, and bearings that would stall a manual lever gun.
Output runs from 70 to 120 grams per minute depending on the model, fast enough for daily service rounds without flooding small fittings. It suits manufacturing lines, construction equipment, automotive bays, and agricultural machinery: anywhere grease points are spread out and a fixed system is not justified.

Portable Pump vs Cordless Gun vs Fixed Systems
Three tools cover mobile greasing, and they split by how much grease you move:
- A cordless grease gun suits a few points per day and rides in a toolbox.
- A 24V portable pump suits service rounds with many points, larger reservoirs, or stubborn fittings that need sustained pressure.
- A fixed automatic system suits machines that must be greased on a schedule without an operator.
If the machine is a vehicle, or stays in one place and needs unattended timed lubrication, that is the job of the 24V DC automatic grease pump rather than a handheld unit. For drum-based work back at the bench, a fixed electric grease pump moves more grease per session. The wider trade-offs between manual, battery, air, and electric options are mapped in the complete guide to grease pumps.
Features That Vary by Model
Within the 24V portable range, the configuration splits by model, so confirm the exact unit before ordering:
- Reservoir capacity up to 600cc on some models.
- LED work light for fittings in dark housings.
- Built-in stand so the pump stays upright between points.
- Adjustable flow for matching output to small fittings.
- Digital grease meter for recording how much each point receives.
- Carrying handle or shoulder strap for field work.
Both rechargeable lithium-ion battery versions and corded 24V versions exist. Battery models favor field service away from outlets; corded models favor bay work where a 24V supply is close and sessions run long.

Limits to Know Before You Buy
- Specs vary by model. The pressure and flow figures are ranges across the line, not a guarantee for every unit. Confirm the rating of the exact model when you order.
- NLGI #2 is the ceiling. Stiffer greases are outside the design. If your application needs a harder grease, choose equipment rated for it.
- Built for intermittent work. Sustained high-output running builds heat. Plan service rounds with pauses rather than continuous pumping sessions.
- It wins where there is no air. In a shop with a compressor, an air-operated pump usually moves more grease per hour. The 24V portable earns its place in the field, in yards, and in buildings without an air supply.
Frequently Asked Questions
How do I choose between a portable pump, a cordless grease gun, and an air-operated pump?
Match the tool to volume and utilities. A cordless gun fits occasional points and a tool bag. An air-operated pump fits shops with a compressor and heavy daily volume. A 24V portable pump covers the middle: regular multi-point rounds where no air line is available.
What pressure can a 24V portable grease pump reach?
Depending on the model, 10,000 to 12,000 PSI. That is enough to open stubborn fittings and push grease into tight pins and bushings.
Which grease can I use?
Greases up to NLGI #2 consistency. Harder greases exceed the design and should not be run through the pump.
How fast does it deliver grease?
Output varies by model from 70 to 120 grams per minute, enough for routine service rounds without flooding small fittings.
Battery or corded: which should I pick?
Battery models suit field service away from power. Corded models suit bays and benches where a 24V supply is nearby and sessions run long.
How much grease does the reservoir hold?
Some models hold up to 600cc. Capacity varies across the range, so check the figure for the exact model you are considering.
Can it run continuously all day?
It is designed for intermittent duty. Long continuous high-output sessions build heat, so work in rounds with pauses rather than nonstop pumping.
What maintenance does it need?
Keep the hose, coupler, and reservoir clean, use the correct grease, and check the power lead or battery contacts regularly.
Is it suitable for construction and agricultural equipment?
Yes. That is a core use case: machines parked in yards or fields where neither an air supply nor a fixed system is available.
