If you live on acreage, a farm or the bush–urban fringe, the right fire pump is one of the most important bits of gear you'll own this summer. When a fire is coming and the mains drop to a dribble or the power goes out, your pump, your hoses and your water supply are what stand between your home and the embers.
First things first: the safest option is always to leave early. But if you do choose to stay and defend, you need the right equipment, set up properly and tested well before the day you need it. That decision belongs in a bushfire survival plan that's built, written down and shared with everyone in the household, not made when the smoke appears.
This guide covers what matters when choosing a fire pump for the 2026/27 season: how fire pumps differ from transfer pumps, diesel vs petrol, single vs twin impeller, how to set it up, and the checks to do before you ever need it.
Before you compare brands or prices, run through this list:
Transfer pumps move lots of water at low pressure. Honda's WB20 transfer pump is rated at 620 L/min but only 32 m of head. Add hose friction, a rise to the roofline and nozzle pressure, and there's little left at the business end.
Maximum Head (m): Fire Pumps Vs A Transfer Pump
Manufacturer maximum head. Orange = fire pumps (our product pages), teal = Honda WB20 (Honda).
CSIRO's Bushfire best practice guide rates diesel pumps the best option, since diesel is less prone to vapour stoppages, less flammable and generally more fuel efficient. Petrol is a Category 2 flammable liquid, while diesel sits in the least volatile Category 4 (WorkSafe Qld).
| Factor | Petrol fire pump | Diesel fire pump |
|---|---|---|
| Start-up | Recoil (pull) start | Key start with recoil backup (Yanmar model below) |
| Fuel storage safety | More volatile (Category 2); goes stale | Less volatile (Category 4) |
| Fuel tank | 3.1–3.6 L on the pumps below | More fuel efficient under load, longer run time |
| Weight | 24–28.2 kg, one-person lift | 70 kg, usually fixed in place |
| Maintenance | Simple; stale fuel is the usual culprit | Robust; keep the battery charged |
| Cost | Lower upfront | Considerably higher |
| Best for | House blocks, small holdings, portability | Larger properties, long run times |

The impeller is the spinning disc inside the pump body that flings water outwards and builds pressure.
If your water sits well below the house, look at a twin impeller such as the Bianco Vulcan BIA-2HP15ABS twin stage fire pump. For flatter blocks, a good single impeller does the job, and the single impeller pumps in our recommendations below are rated to 60–74.5 m of head.
Flow (L/min) is how much water comes out. Head (metres) is how high the pump can push it, which doubles as a pressure rating: 1 m of head is about 9.81 kPa, so 74.5 m is roughly 730 kPa. Maximum head comes at almost no flow and maximum flow at almost no head, so no pump hits both at once.
Maximum Flow Rate (L/min)
Manufacturer maximums from our product pages. Output at the nozzle is lower.
NSW RFS pumping doctrine (Use of Water and Water Chemical Mixes) gives handy rules of thumb: about 350 kPa at a standard nozzle, about 100 kPa of friction loss per 30 m of hose in typical RFS use, and 10 kPa per metre the nozzle sits above the pump. For example:
Extra outlets split the flow. The same doctrine allows no more than about 100 L/min through a 25 mm line or 250 L/min through a 38 mm line in pump relays. Leave headroom.
The easiest way to cover both ends is a matched kit, such as the Water Master 1.5" Fire Hose Kit or the Bianco BIA-FFHK Fire Fighting Hose Kit.
A fire pump is a tool inside your plan, not a replacement for one. Before summer, sit down with everyone in the household and agree on:
Your state fire service (CFA, RFS, CFS, QFES, DFES, TFS) has free templates to help you write it down. In NSW, you can build yours online at myfireplan.com.au. Do it, then practise it.
The CFA's planning template says to test pumps and hoses and check you've got enough clean fuel. Before summer:
Before every start, take 30 seconds to check:
The Bureau of Meteorology declared El Niño on 16 June 2026. In its 15 September update, the Bureau called it firmly established at strong levels, likely to strengthen through spring and persist into autumn 2027 (BoM). Around half of the climate models the Bureau surveys suggest it could peak among the strongest El Niño events since 1950.
El Niño is often linked with drier, warmer conditions, although the Bureau stresses that strength doesn't always match impact. Large parts of the country have been wetter than usual since January 2026 (BoM), and all that growth turns to fuel as it dries. As the NSW RFS puts it, grass and crops become more susceptible to fire as they dry out (cure).
The Bureau's long-range forecast shows above-average temperatures likely for most of Australia, and below-average October–December rainfall likely for parts of southern NSW, Victoria and Tasmania. AFAC's Spring 2026 Seasonal Bushfire Outlook flags heightened risk across northern and south-eastern NSW, south-east Queensland, north-eastern Tasmania, parts of WA, SA and Victoria, and much of the NT. The World Meteorological Organization puts the odds of El Niño lasting through summer at close to 100%.
So buy, service and test now. Leave it until the first smoky week and you're competing with everyone else for pumps, parts and a mechanic.
Our current fire pumps, with specs from our product pages:

Best for a house plus sheds, running two lines. Honda GX200 petrol, 570 L/min, 74.5 m, 27 kg.
Australian-assembled with a 2-year pump warranty. Honda GX160 petrol, 390 L/min, 74.5 m, 6 m suction lift, 28.2 kg.
Best for larger properties and long run times. Yanmar L70N diesel, key/recoil start, 640 L/min, 60 m, 70 kg.
4 m suction hose with strainer, 6 m 3/4" delivery hose with nozzle.
A fire pump also earns its keep outside fire season: filling troughs and tanks, washing down machinery and sheds, and moving water around the property.
It's better than nothing, but it won't give you the pressure to reach the roofline or push water through long hose runs. For defending a home, use a fire pump.
Yes. CSIRO lists pools, dams and tanks as good backup sources when set up with pumps and hoses (CSIRO). Keep the strainer submerged and the suction hose short.
Victoria's Bushfire Management Overlay requires at least 10,000 L per dwelling, and the CFA recommends 20,000 L where there's no hydrant. Check your state's requirements.
No. Mains pressure and power can both fail during a fire. A petrol or diesel pump on a dedicated water supply is far more reliable.
Only if your water sits well below the house or you're running long uphill hose lines. For most flatter blocks, a good single impeller pump does the job.
Run it under load for about ten minutes every couple of months, and do a full check before summer.
Close to your water supply, on a stable base, shielded from radiant heat, and somewhere you can reach safely.
No, but a pump can feed roof sprinklers. Either way, you still need a water reserve, fittings and a plan.
Decide that in your bushfire survival plan, well before summer. The NSW RFS says your safest option is to leave early.
Sort your water, match the pump to your block and test it before the first hot, windy day. Browse our range of:
