How to Improve Fire Pump System Reliability and Safety through Proper Selection

Fire pump sets are often required when the local water system cannot provide sufficient pressure to meet the design hydraulic requirements of the fire sprinkler system. This typically occurs in multi-story buildings or systems that require relatively high terminal pressures at fire sprinklers in order to release large volumes of water, such as storage warehouses. A fire pump is also required if the water supply is provided from above-ground or underground storage tanks.

Diesel engine fire pump is also called “engineering diesel engine fire pump set”. The diesel engine fire pump set has the characteristics of good starting characteristics, strong overload capacity, compact and reasonable structure, convenient maintenance, simple and reliable use, etc. The unit is equipped with protection functions such as overspeed, low oil pressure, three start failures, high water temperature, low oil level, and low battery voltage. 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 part of the applied water supply and are powered by electricity, diesel. They activate when the pressure in the fire sprinkler system drops below a certain level and provide a flow of water to the sprinkler system at very high pressure, which is then discharged onto the fire.

If the fire pump is corroded, it should be inspected by a qualified professional. Depending on the extent of the corrosion, the pump may need to be repaired or replaced. The professional may also need to inspect the entire system for any other potential issues. In some cases, a fire pump may need to be replaced if the corrosion is severe and cannot be repaired.

Start and stop, with the advantages of flexibility and small footprint.

Fire pumps play a pivotal role in fire protection systems by ensuring a reliable and pressurized water supply for firefighting efforts. When a fire breaks out, immediate access to water at a sufficient flow and pressure is critical to containing and extinguishing the flames. In many cases, the water supply provided by municipal water mains may not be adequate, necessitating the use of fire pumps to boost water delivery to firefighting equipment.

Fire pumps are especially crucial in large industrial or commercial buildings, as they ensure that every corner of the facility has access to water for firefighting. Without fire pumps, there might be inadequate pressure or flow, resulting in a delayed response, potentially leading to greater fire damage.

Yes, firefighting pumps are often used in conjunction with water tanks, lakes, rivers, or other water sources to ensure a constant and adequate water supply during firefighting operations. Portable water tanks or drafting equipment can be employed to access water from non-traditional sources when necessary.

EDJ series fire pump sets are mainly installed in fire trucks, fire extinguishing systems or other fire fighting facilities, and are special pumps used to transport liquids such as water or foam solution.
The fire pump set includes a main pump connected to the electric motor, a backup pump connected to the diesel engine, jockey pump, pressure vessel, controller for manual or automatic operation of the system and standard accessories mounted on the base.
