400gpm@90psi EDJ Fire Pump Set

Electric fire pumps are used in various water environments, not only to meet the general water supply but also to be a good helper for fire-fighting water. The electric fire pump is manufactured with good structure and workmanship. It has a wide range of performance, and is easy to use and operate for a long time. The motor fire pump is aimed at various fire water environments, so the selection should also be based on the actual demand environment, performance parameters, etc.

The engine cooling system of the diesel engine fire pump adopts double closed-loop heat exchangers. The system has the advantages of high cooling efficiency and little impact on the ambient temperature of the pump room. The cooling water flow direction is controlled by a ball valve from the pump outlet pipe to the heat exchanger, so that the cooling water temperature of the machine body is between 85 and 95 °C. If the water temperature is too high, you can increase the opening of the ball valve, increase the heat dissipation capacity of the heat exchanger, and reduce the temperature of the engine cooling water.

Fire pump refers to a clean water pump used for fire water supply, and a single water pump with a treatment medium temperature lower than 80 degrees and non-corrosive. The pump unit is a joint operation of multiple fire pumps to ensure the quantity and stability of water supply. The electric fire pump set adopts multiple fire pumps powered by electric motors. The general fire water supply environment is equipped with one electric and one diesel fire pump as the reserve water pump to ensure sufficient emergency water consumption. The main components of the electric motor fire pump set are the motor and the pump body. The subdivision of the pump body is the pump casing, impeller, pump shaft, bearing, coupling, sealing form, water pipe, etc. The specific fire pump model is determined according to the environment and performance requirements. At the same time According to the material quotation required by the customer, accurate selection is conducive to on-site use and reduces failure problems.

Fire water pump refers to the water supply pump used to ensure the system pressure and water volume in the fire water supply system. The fire pump transfers energy to the water through the rotation of the impeller, thereby increasing the kinetic energy and pressure energy of the water, and transporting it to the fire extinguishing equipment to meet the water volume and water pressure requirements of various fire extinguishing equipment. Such as fire hydrant pumps, sprinkler pumps, fire transfer pumps, etc.

Diesel fire pumps are ideal for applications where a separate pump room already exists or where the pump room is located on an exterior wall. Facilities using diesel fire pumps include warehouses, aircraft hangars and industrial facilities. Since they have a larger footprint than electric fire pumps, they are not suitable for installations where space is small. Unlike diesel pumps, electric fire pumps can be located inside buildings. Office buildings and apartments are often equipped with electric fire pumps. In addition, upper floors sometimes install an additional electric fire pump above ground or basement to increase water pressure.

The fire-fighting water provided by most fire-fighting water sources needs to be pressurized by fire-fighting water pumps to meet the requirements for water pressure and water volume during fire-fighting, which is an important part of fire-fighting. In daily use, we often encounter fire pumps vibrating or making abnormal noises. What is the problem?
1. The installation is not firm and the fasteners are loos

2. Wear between impeller and seal ring

3. Improper installation of pump body and pump shaft

4. Cavitation causes abnormal sound inside the pump
