Fire pump is one of the fire-fighting equipment, its function is mainly used to transport water or other fire-extinguishing liquid for fire-fighting. Pumping water with equipment such as fire pumps has a very high water delivery efficiency. There are many types of fire pumps, and the air pumping methods of different fire pumps are also different. Sprinklers, fire hydrants, and water cannons and window sprays commonly used in business have the same pump-starting principle, but the fire-fighting linkage principle is different.

Regular maintenance is crucial to ensure the reliability of outdoor fire pumps. This includes checking and changing engine oil, inspecting and cleaning intake strainers, testing pump operation, and ensuring all hoses and connections are in good condition. Additionally, regular testing and inspection by qualified professionals are recommended.

The diesel pump + jockey pump can be started normally in case of power failure. Jockey pump ensures the presence of liquid in the fire pipeline. When a fire occurs, the diesel pump starts to work within ten seconds to control the fire.
