Diesel engine fire pump is a common fire fighting equipment, especially suitable for use in places without electricity supply. The diesel engine fire pump uses a diesel engine as a power source to convert the work of the pump into hydraulic power to achieve a certain flow and pressure. It is mainly used in building fire protection, engineering fire protection, water source fire extinguishing and other fields.

Since the operation of the electric water pump is inseparable from electricity, and the power supply is often cut off at the scene of a fire accident or the power supply is automatically closed due to a fire. Even if we are equipped with a dual power supply switching device, it is really impossible to ensure that the power grid must be normal when the fire alarm signal comes. Therefore, starting and running a diesel engine fire pump completely disconnected from the grid becomes the preferred equipment for backup fire protection facilities! The driving power of diesel engine fire pumps is completely different from that of electric water pumps, so their daily protection and treatment are also different in many places!
