Small diesel fire pump system consist of diesel engine, motor pump and jockey pump. It mainly used in warehouses, docks, airports, petrochemical, power plants, liquefied gas, textiles, ships, oil tankers, government embassies, military bases, administrative buildings, port commercial buildings, high-rise buildings, hotels, offices, hospitals, correctional institutions, nursing homes, schools and other occasions of a fire service.

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.

Fire pump systems are comprised of various components, each playing a critical role in ensuring their proper function. Some of the key components include:

Fire Pump: This is the heart of the system, responsible for pressurizing the water and sending it to the fire protection devices.

Controllers: Controllers monitor the system, automatically starting the pump in response to a fire alarm signal and providing system status information.

Suction and Discharge Piping: Properly designed piping is essential for efficient water flow. Suction piping brings water to the pump, while discharge piping carries it to the fire protection devices.

Pressure Relief Valves: These safety valves release excess pressure to prevent damage to the system.

Valves: Various valves control water flow within the system, allowing for isolation, testing, and maintenance.

These components work in concert to provide reliable water distribution in case of a fire.
