SPECIALISED PUMPING AND WATER STORAGE SOLUTIONS ACROSS AUSTRALIA

Fire pumps function either by an electric motor or a diesel engine.  If the  building configuration requires power independent of the local electric power grid, a pump using an electric motor may utilize the installation of an emergency backup generator.

The fire pump starts when the pressure in the fire sprinkler or hydrant system drops below a predetermined threshold. A sprinkler system pressure drops significantly when one or more fire sprinklers are exposed to heat above their design temperature, and opens, releasing water.  A hydrant system pressure drops when a hydrant landing valve is opened and water is allowed to flow freely. Alternately, fire hose reels or other firefighting valves are opened, causing a pressure drop in the fire main.  System leaks are also a culprit! 

Fire pumps are needed when the local municipal water system (towns main) cannot provide sufficient pressure and/or flow to meet the hydraulic design requirements of the fire sprinkler or hydrant system. This usually occurs if the building is very tall, or in systems that require a relatively high pressure at the fire sprinkler in order to provide a large volume of water, such as in storage warehouses. Fire pumps are also needed if fire protection water supply is provided from a water storage tank.

Our in-house specialist diesel mechanic and skilled technicians can safeguard thorough testing and maintenance of your pumps, strictly adhering to Australian Standards AS1851.

We provide a start to finish solution to not only ensure your system is compliant, but to make sure the longevity of the equipment.  Fire pumps and tanks are extremely expensive items to replace - and having to do so through poor maintenance or simple, unavoidable errors can be not only frustrating but financially debilitating.

When fire pumps are required it is very likely that a fire water tank will be needed too.  Fire tanks are used for storage of water for firefighting purposes and range in size from small 10kl break tanks to Mega-Litre full capacity tanks. 

Water storage for fire protection is governed by the Australian Standards AS2304 with respect to design, capacity, construction, installation, commissioning and maintenance. Tanks have vastly different capacities to meet the specific site requirements and can be constructed in a number of different ways.  Such as:
