The diesel engine fire pump is usually used as a backup facility, so it will only start automatically when the fire signal comes, and when the electric water pump fails or the power supply is cut off. When it has a device for starting the pump at ultra-low pressure, its matching electric water pump control cabinet should also have a device for starting the pump at ultra-low pressure, and the lower limit of the two pumps should have a certain pressure difference.

Setting up the fire pump control system correctly is crucial to ensure the pump operates efficiently and reliably during emergencies. Here are the general steps to set up the fire pump control

Fire fighting pumps are used in a wide range of settings, including residential, commercial, industrial, and wildland firefighting situations. They are also used in fire trucks, aircraft firefighting systems, and marine firefighting applications.

Last month our customer from Ecuador ordered 2 sets EDJ fire pump set from our factory. The gpm and bar he needs is 350gpm@135psi, and he will use these two fire pump system in his factory.

Diesel engine fire pump is suitable for high-lift and high-flow fire-fighting water supply environment or as a backup fire-fighting water supply pump. The reason is that the diesel engine has strong power and can be used with large-flow fire-fighting deep well pumps, and the diesel engine fire pump has the characteristics of self-start after power failure. It can provide emergency water supply and is a good choice in fire pumps.

First of all, check whether the oil level is normal and cannot reach the oil mark line on the normal surface. If it is not, we must replenish it in time, but remember one thing, it cannot exceed the amount of the oil quantity indicator line.

Secondly, check the radiator. The water is appropriate. If it is not added in time, the water that needs to be added must be clean water, as long as it is clean water, or tap water is fine. Why not use groundwater, because impurities in groundwater can easily form scales in the water tank, which affects the cooling effect and is also prone to failure. In winter, we drive to preheat the car, add coolant to the car, and the fire pump is no exception. The weather in the north is very cold, so add the coolant to the fire pump according to the actual temperature.

Finally, check the installation of each part of the fire pump, such as whether they are stable, the connection between the screw and the screw, if there is any looseness, tighten the screw in time. To clean the fire pump, soak a canvas or dry cloth and wipe slowly on the body or on surfaces made of grease or dust.

Fire pumps should be tested on a regular basis according to national and local regulations. Common testing frequencies are monthly, quarterly, annually, and five-yearly, with different tests conducted at each interval.
