Diesel engine fire pump has high efficiency, long operating life and high reliability. It can be used in independent fire water supply systems, and can be used in fire protection and living shared water supply systems. It can also be used in construction, municipal, industrial and mining, water supply and drainage, ships, field operations and other occasions .

The main reason to have a fire pump is to work with the fire protection system in case the water supply does not have sufficient pressure. High structures or large warehouses that carry large amounts of water require the help of a fire pump. It increases the pressure of the water flowing into the fire suppression system, allowing the system to release the maximum amount of water while extinguishing the fire.
