What are the characteristics and advantages of diesel engine fire pumps?

Electric motor fire pumps are used in various water environments, not only for ordinary water supply but also as a good helper for fire water. The electric motor fire pump is manufactured with good structure and technology, with a wide range of performance, simple operation and long-term use. The electric motor fire pump is aimed at various fire water environments, so the selection should also be based on the actual demand environment, performance parameters, etc.

The biggest difference between the diesel engine fire pump and the electric water pump is that it has its own independent power supply system, which can ensure the normal operation of the project without power or power supply. Its role is self-evident, and it can be said to be a great helper in fire emergency .

Fire sprinkler systems are an important part of life safety in buildings. International building codes allow some exceptions when buildings are “fully watered”, such as reducing rated spacing, reducing hydrant flow requirements, increasing exit travel distance, and increasing building height and area. These exceptions are allowed so that in the event of a fire, the sprinkler system will suppress the fire enough that occupants can safely evacuate the building and that the spread of the fire is contained before the fire department has fully arrived to extinguish it.
