The diesel engine fire pump has the characteristics of good startability, strong overload capacity, compact structure, convenient maintenance, simple use, and high degree of automation. It is a fire-fighting equipment with reliable performance. It can completely meet the fire water supply in various occasions of warehouses, docks, airports, petrochemicals, power plants, liquefied gas stations, textiles and other industrial and mining enterprises.

Fire pumps are not always running; they typically start automatically when a drop in water pressure is detected in the fire protection system.

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.

1. The performance of the fire pump should meet the flow and pressure requirements of the fire water supply system.
2. The power of the driver equipped with the fire pump should meet the requirements of the power required for operation at any point on the performance curve of the selected pump’s flow and lift.
3. When a motor-driven fire pump is used, a dry-installed fire pump with the motor should be selected.
4. The fire pump should be installed dry, and the pump should be placed outside the pool, and the submersible pump cannot be directly placed in the water for water absorption.

Dual power fire pump consists of an electric motor driving fire pump, a diesel engine driving fire pump, a common fire pump controller, pressure vessel, standard fittings and base frame.

1. Make sure all valves are open and the system is in good working order.
