Aussie has the power to help control fires

The current fire risk has been declared as the “worst fire season in history” not just on the East Coast but other states as well and this reminder to farmers and homeowners is to be alert and that early preparation is vital

The current fire risk has been declared as the “worst fire season in history” not just on the East Coast but other states as well and this reminder to farmers and homeowners is to be alert and that early preparation is vital With Australia’s farmland, country towns and even capital city edges facing a potentially catastrophic fire season, everybody needs to be prepared for the critical danger period ahead.

For many, the move to more efficient, capable fire-fighting equipment is a must.

Volunteer brigades around the country are preparing upgrades, and where appropriate to the latest technologies.

Australian Pump Industries is a leading supplier of portable lightweight fire pumps.

When we spoke to Chief Engineer John Hales, he weighed up some basics on what he has learnt through the evolution and development of the company’s pump range.

Capability is everything In a fire, having the ability to get the fire out fast is everything. It’s not how much pressure you have but how much water can be applied at pressure!

Australian Pump has been behind the push to improve the capability and pressure flow characteristics of their product range over the last 25 years.

During that time, they have developed pumps that can deliver more water at pressure, even going into production with a twin impeller high pressure pump with 76mm (3-inch) ports.

The company started with the concept of the Aussie Fire Chief.

That pump had a larger  diameter impeller.

The hydraulics combination of the heavy-duty impeller and volute is perfectly matched to either petrol or diesel engines produced by the world’s best manufacturers.

All units are carefully tested by the engineers from Yanmar, Honda and Kubota to ensure that there is plenty of reserved power to drive the product even in an extreme situation.

Pump design counts.

When Aussie developed the Fire Chief, they started out thinking about the application and opportunities for the design without worrying too much about cost.

“Price is a factor of course but we believe if you start out with a 76mm (3-inch) instead of a 51mm (2-inch) pump you ultimately wind up with more capability because of the ability to use bigger impellers and volutes.” said Hales.

“The trick is to make sure the balanced impellers and volute design does not over-load the engine,” he added.

The big belly body on the Fire Chief gave the company room to design a 190mm (7.5-inch) diameter impeller.

The huge impeller, weighing 2.5 times more than competitors, and made of top quality aluminium material, works in combination with a preciously machined volute.

The combination of impellers and volutes means the water passages produce more pressure but, deliver more water as well.

Water in … water out.

The company also worked to fit a bigger suction port into the pump.

“We built in a 51mm (2-inch) flanged, removable suction port that gives the user real advantages.” said Hales.

“The more water that can get into the pump provides the operator with an inherent advantage over small suction port pump.” he added.

Hales also went onto say that the larger port also means you can accommodate a bigger check valve to help the self-priming process.

That results in the Fire Chief lifting water through a vertical 7.6m (25ft) suction line.

“We see fire pumps with a 38mm (1.5-inch) suction inlet and 4 separate outlets.

How on earth can that pump ever be expected to push water through more than one outlet from a 38 mm (1.5-inch) suction.

It’s marketing gimmick not a practical solution.” said Hales.

Pump stability important

Getting the pump to sit firmly on a base can be a big thing in the panic and excitement of a bushfire situation.

Aussie started out with the Fire Chief with two steel skids with anti-vibration mounts to stabiles the pump.

“In the heat of the moment a tug on the delivery hose and topple the pump,” said Hales. “That can only happen if there’s no operating base on the machine.”

Recent developments of the Fire Chief in its Red Brigade configuration include a heavy-duty roll frame on anti-vibration mounts. That makes the pump even more stable.

The Fire Chief produces a whopping pressure of up to 100 PSI, equivalent to a 75m (246ft).

Flows are up to 450 litres/min maximum but the key performance figure is the duty point of operation.

“The Chief can pull 200 lpm at a 50 metre head” said Hales. “That’s substantially more than any of our competitors and makes the performance of third world cheap pumps that are flooding Australia look totally inadequate,” said Hales.

The expanding range

Today, after working closely with farmers, home owners and even national parks and fire-fighting authorities, Australian Pump has expanded the product line up to make pumps specifically suitable for the local market.

The range now includes both petrol and diesel drive machines, single and twin impellers and even the mighty Brigade Boss series that delivers huge flows at pressure.

These big pumps all come with roll frames with bases and anti-vibration mounts. The diesels come with galvanised steel, or more recently, stainless steel frames for protection against corrosion.

Five year warranty

Australian Pump is the only company that offers a 5-year warranty on their fire-fighting pumps.

“That’s because we believe in the product and know just how good it is” said Hales.

“That 5-year warranty is unique in the industry and has not been followed by any of our competitors. That tells you something.” he said.

Although Aussie Pumps products are made to the highest standards prices are competitive.

“We don’t believe in fake prices and fake discounts” said Hales “We have real prices and we sell through great distributors who support our philosophy.” added Hales.

A new catalogue, Aussie Pump Smart, is available for all those interested in “Fire Pumpology.”

The publication aims to help farmers and professionals select the right pump for any duty.

Check through the catalogue as it shows roughly 500 options, the biggest range not only in Australia but in the southern hemisphere.

“It makes pump selection easy,” said Hales.
