A Diesel Engine Fire Fighting Water Pump is used as a backup fire-water pump, providing a source of water for firefighting in the event that treated fire-water storage tanks run empty. This type of fire-water pump is also commonly used for water transfer and other farm pump jobs that require pressurised water, such as boom spraying, stock watering, and machinery washdown.
There are many types of diesel fire fighting pumps to choose from. Some are able to deliver higher water pressure than others, which is important for the performance of the pump. The flow rate is another factor to consider, with higher flow rates allowing the pump to move more water in a shorter amount of time. Some models of fire fighting pump are available with twin impellers, which create more pressure than single-impeller pumps. This allows the pump to squirt water further and more quickly, although it does reduce the water flow volume.
Choosing the right water pump for your needs can be a daunting task with so many options available on the market. Generally, there are three main considerations when selecting a pump for your job: power, head, and flow rate. Each of these factors can affect the performance of the pump, and it is important to understand how each works before making a purchase.
The power of a diesel fire fighting pump is determined by its rated capacity and the maximum pressure it can achieve at its rated head. Ideally, the water pump should be rated for at least 150% of its rated capacity at its rated head, and it should maintain a residual pressure of about 10 barg (gauge pressure) at the hydraulically most remote hydrant.
In addition to the rated capacity and maximum pressure, you should also take into account the kW output of the diesel engine, which determines how much power the pump can produce. Typically, the more powerful the diesel engine, the higher the water pump’s rated capacity and maximum pressure.
When comparing different diesel fire fighting pumps, it is also important to note their flow rate and total head. Flow rate is the amount of water the pump can move in a minute, while total head refers to the height the water can be lifted from its initial source.
A large range of diesel fire fighting pumps are available, including both single and twin-impeller models. These models differ in terms of their water transfer capabilities and power consumption, and some can be purchased with or without a roll cage and with either electric or recoil start. They also come in a variety of hose connections, and some have bolt-on replaceable suction and discharge caps that are easy to remove and attach. They are made from durable cast aluminium and powder coated to help protect them from damage. Many models also have a high-quality Yanmar diesel engine, and some come with a warranty for added peace of mind.
