A fire fighting pump is a device used to deliver water at high pressure. The pump may be powered by gas or diesel engines and is commonly belt-driven. It is important to know how to operate the pump correctly to get the most out of it. Volunteer firefighters often lack the opportunity to attend as many training classes and on-the-job experiences as their full-time counterparts, so it is essential that they understand the ins and outs of how to use the fire department’s pumps.
A good fire fighting pump will be designed for ease of operation and maintenance. For example, it should have easy-to-read gauges for the maximum head and the suction and discharge pressures. Moreover, the pump should have a robust roll bar frame and ergonomically positioned handles for ease of handling and maneuverability. It should also be easily transportable from the water source to the site where it will be used.
Another feature to look for in a fire fighting pump is its self-priming capability. This means that the pump will be able to retain and hold water after it is first primed, even when it is not being used. It is also important to look for a pump with a solid, sturdy construction and that has a lot of metal components. This will be more durable and will stand up to the demands of the fire fighting industry.
In terms of flow rates, it is a good idea to find out whether the pump is rated for transfer or high pressure spray/delivery. A transfer pump will move large volumes of water quicker than a high pressure fire fighting pump but at a lower PSI capacity. High pressure fire fighting pumps can deliver higher volume and a wider coverage area for spraying and are available with both petrol and diesel engine options.
It is also worth noting that a fire fighting pump’s pressure will be compromised by friction loss when the water moves long distances in pipes and hoses. It is a good idea to have access to a fire hose friction loss chart or cheat sheet so that the pump operator can calculate and predict the nozzle pressure they will be getting after friction losses are factored in.
One of the most critical functions of a fire fighting pump is its ability to be easily starting. When buying a fire fighting pump, look for options such as an electric or recoil starter that is simple to operate. Also, it is a good idea to buy a pump that has a warranty that will protect you from any damage or defects during the time you own and operate the pump. Lastly, it is a good idea to choose a pump that is backed by a national network of accredited agents throughout the country in case you need help or maintenance. This will give you peace of mind and will ensure that your pump is always ready to perform when it is called upon.
