What should be paid attention to in the selection of fire pump

There is a combination equipment that uses diesel as fuel for firefighting, but it is usually used as a backup firefighting facility, because it can only be started automatically when the firefighting signal comes, and the electric water pump fails or the power supply is cut off, that is, the diesel engine firefighting pump set. It is very different from the electric fire pump in that it has its own independent power supply and storage system.

Fire pumps work by drawing water from a water source (such as a dedicated water tank or municipal supply) and pressurizing it before delivering it to the fire sprinkler system or hose lines.

1. The function of the diesel fire pump is very powerful. We can set the control time during use, such as: preheating, pre-lubricating or timing start. The use of high-tech has made some complicated and time-consuming things easier in the past. The preheating setting greatly reduces the preparation time for rescue, allowing firefighters to rescue the first time. In the face of disasters, time is money and time. is life.
2. The head and flow can be controlled by adjusting the speed of the engine, and the height and size of the water flow become easier to control. When the nozzle is in a stable state, by controlling the engine, we can accurately spray the water source at the fire point to extinguish the fire, which also reduces the difficulty of rescue for firefighters.

The small EEJ fire pump set is suitable for low buildings. The fire pump set consists of two ISW electric pumps and one CDL jockey pump.
