Fire Fighting Pumps
Don't leave the safety of your family and your home to chance. With increasing temperatures, it's becoming a necessity to become fire ready by equipping your home and workplace with the best safety equipment, and that includes a fire fighting pump. Fire pumps supply water at a much faster rate than you could ever supply by hand, making this an essential tool in your summer fire plan. A fire fighting pump can also be used to fill a swimming pool with water, irrigating a garden, draining a flooded area, or washing down farm machinery.
A regular garden hose dispenses water at 30 to 40 PSI. Check the specifications of the fire pumps you are considering. For fighting fires, irrigation, and equipment washing, you need approximately 100 PSI. If the specs don't mention the PSI, then you can multiply the "maximum head metres" by 1.42 to get a PSI value.
Fire fighting pumps also come in different flow rates. For residential use, somewhere between 200L to 1000L per minute is a good range, depending on the distance you need to pump the water and how much water you want to pump. You also need to consider any incline between where the fire pump will be located, and where you need the water to go. If you need to fight a fire uphill from your pump location, then you will require a higher "maximum head" value. The maximum head value indicates the height at which you will have zero water flow, so a maximum head of 40 means that trying to pump water 40 metres above the pump location won't work -- you'll have zero water flow.
Try to ensure that your fire fighting pump has a high quality build and engine, and includes a self-priming capability so there are no air blockages, which ensure that your pump is always ready to go. Consider whether you want a fixed or mobile pump. Also consider whether the pump is petrol, diesel, or electrical -- although it's important that you have a reliable back-up generator if you choose an electric-powered fire pump. Whether you get a single impeller pump or a twin impeller -- that's the rotor used to increase the pressure and flow of the water -- you can be safe in the knowledge that you are one step ready for fire season.
