Electric AdBlue® pumps come in two main families: low-voltage DC pumps (12 V or 24 V) and mains-powered 240 V pumps. Both move AdBlue from a container into a vehicle. The right choice depends less on the pump itself and more on where you dispense, how much you move and what power is available.
12 V and 24 V pumps: made to move
DC pumps run from a vehicle or equipment battery. That makes them the natural choice when the AdBlue has to travel to the machine rather than the other way around.
Where they suit:
- Service utes and trucks carrying an IBC or small tank to machines on site.
- Farms topping up tractors and headers in the paddock.
- Construction crews moving between jobs.
- Remote locations with no mains power.
Things to watch:
- Match the pump voltage to the vehicle. Many trucks run 24 V, while utes and light vehicles are 12 V.
- Use cable of the right gauge for the distance and fit an inline fuse. Undersized cable causes voltage drop and a sluggish pump.
- Check the duty cycle. Many compact DC pumps are rated for a set number of minutes on, then a rest.
- Secure the container properly. A full IBC weighs about 1,150 kg and must be restrained on a vehicle.
240 V pumps: built for fixed sites
Mains-powered pumps suit depots, workshops and yards where vehicles come to a fixed dispensing point. They are often part of a permanent set-up with a hose reel, meter and filter.
Where they suit:
- Transport depots filling many vehicles each day.
- Workshops that top up customer vehicles.
- Bulk tank installations.
- Service stations and card-operated dispensers.
Things to watch:
- Any fixed wiring or new power outlets must be installed by a licensed electrician.
- Protect the pump and electrics from weather, especially if the IBC or tank is outdoors.
- Position the power supply so leads are not run across walkways or through puddles.
Side-by-side comparison
| 12 V / 24 V | 240 V | |
|---|---|---|
| Power source | Vehicle or equipment battery | Mains outlet or fixed wiring |
| Best for | Mobile and remote use | Fixed depots and workshops |
| Installation | Simple; battery clamps or loom | May need an electrician |
| Typical duty | Intermittent top-ups | Frequent or continuous fills |
| Main risk | Flat battery, voltage drop | Weather exposure of electrics |
Flow rates vary widely by model in both groups. Always read the rated flow and duty cycle on the manufacturer's spec sheet instead of judging by voltage.
What stays the same whichever you choose
The power supply is only one part of the decision. Whatever pump you choose, the rules for AdBlue handling do not change:
- Compatible materials only. The pump body, seals, hose and fittings must suit AdBlue: stainless steel, polypropylene, HDPE, PTFE, EPDM or fluoroelastomer. Avoid brass, aluminium, copper and galvanised parts.
- Dedicated equipment. Never use a pump that has handled diesel, oil or coolant, even after flushing.
- Filtration. An inline filter after the pump helps protect nozzles, meters and vehicles, particularly on bulk tanks and dusty sites.
- Don't run dry. Many AdBlue pumps are diaphragm type and tolerate brief dry running, but long periods without fluid shorten their life. Shut off when the container is empty.
Some operations use both: a fixed 240 V system at the depot and a 12 V kit on a service ute for machines that cannot come in.
Thinking about the next few years
It is worth choosing with growth in mind. A single 12 V kit on a ute can work well for a small fleet, but if you expect to add vehicles, a fixed 240 V point in the yard may save time later. Equally, a depot that starts sending service crews out to machines may find a 12 V kit a useful addition rather than a replacement. If you are unsure, list how many vehicles fill at the depot each week and how many are topped up in the field. The larger number usually tells you where to start.
One thing you can do today: check the voltage of the vehicle you plan to mount a DC pump on. Look at the battery label or the owner's manual. Ordering a 12 V pump for a 24 V truck, or the reverse, is a common and avoidable mistake.
