[0002] Diesel engine fire pumps have the characteristics of high flow and high head, and the diesel engine has good starting characteristics and fast starting speed. It does not need to be in standby mode all the time, which is energy-saving and efficient. Diesel engine fire pumps are usually used as backup facilities. They start automatically when the electric water pump fails or the power is cut off. They are mainly suitable for various fire fighting conditions such as fire hydrants and sprinklers. They are also widely used in warehouses, airports, petrochemicals and other occasions.
