12V Grease Pumps
A 12V grease pump runs off the battery platform a service truck or farm machine already has. No air line, no mains outlet — a cordless gun or a dual-voltage 12/24V DC pump unit feeds grease where the vehicle is, which is why mobile maintenance lives on this class of equipment.
IsoHiTech catalogs eight models here: 12V and 20V cordless grease guns, dual-voltage 12/24V DC pump units for progressive systems, and cartridge pumps for mobile mounting. Most dual-voltage members are also cataloged under the 24V pump category.
Choosing a 12V System
Start from what the lubricant has to reach — one bearing, or a full progressive circuit:
| Job | Type | Cataloged as |
|---|---|---|
| Point lubrication by hand, anywhere | 12V cordless gun | 12V gun, 8,000 PSI class, 400g cartridge |
| High-flow point work | 20V Li-ion gun | 20V gun, brushless platform |
| Progressive system on a machine | Dual-voltage pump unit | DZGK 24V/12V, IHI SK-505BM, CSK |
| Cartridge-mounted mobile lube | Cartridge pump | Bijur Delimon FS, 120 bar |
| Replacing a discontinued OEM pump | Direct replacement | P203 replacement, SKF Lincoln compatible |

12V Grease Pump FAQ
12V pump or cordless gun — which do I need?
A gun is for points you reach by hand: fast setup, one fitting at a time. A pump unit is for machines: it drives a progressive or single-line circuit on a timer, feeding many points whether anyone is there or not. Mobile trucks usually carry a gun and fit pumps to the machines they service.
What does dual voltage 12/24V mean?
The pump motor accepts either a 12V or 24V DC supply, so the same unit fits light vehicles (12V) and trucks or heavy machinery (24V). The DZGK, CSK, and SK-505BM units on this page are dual-voltage — also cataloged under 24V grease pumps.
Will a 12V pump run a progressive system?
Yes — the CSK and SK-505BM units are built for progressive circuits, feeding divider blocks that split the flow to every point. Match the pump’s pressure class to the block count and line length before ordering.
What kills battery grease guns early?
Cold grease and empty pumping. NLGI 2 grease at low temperature makes the motor work at stall; running the gun “to be sure” after the cartridge empties hammers the piston. Warm the pail, watch the level window, and the brushless platform outlasts the cheaper ones.
Can I get one pump to replace an obsolete OEM unit?
Often yes. The cataloged P203 replacement is a direct SKF Lincoln-compatible swap. For other discontinued units, send the machine and pump numbers through the contact page and IsoHiTech will confirm the equivalent in writing.
