horizontal multistage centrifugal pump is multistage single suction sectional centrifugal pump with excellent hydraulic model, it has advantages of high-efficiency, energy-saving, wide performance range, operating safely and steadily, low noise, long life and convenience for installing and repairing etc.

In the daily maintenance of the fire pump, we need to meet the following requirements: we need to ensure that the water inlet and outlet pipes, the various components of the controller, and the diesel engine system can work normally, and ensure that the power part is firmly connected to the water pump. We also need to check the opening status of the pump room, fire pump system, and various valves to ensure that the pump room has good heat dissipation conditions and that the components of the pump are in normal working condition.

Horizontal multi-stage fire pumps can be used to transport clear water without solid particles and liquids with physical and chemical properties similar to water. It is mainly used in pressurized water supply for fire protection system, heating, bathroom, boiler cold and warm water cycle pressurization, water supply for air conditioning and refrigeration system, and equipment matching and other occasions.

Fire pumps are subject to rigorous testing and maintenance protocols to ensure they are always ready to operate in an emergency. This typically includes regular weekly or monthly churn tests, where the pump runs without discharging water, and annual flow tests, which verify that the pump can achieve its rated flow and pressure. These tests are crucial for identifying potential issues, such as wear and tear on components, blockages in the piping, or problems with the power supply. Additionally, fire pumps must be inspected for leaks, corrosion, and other signs of deterioration. Regular maintenance, including lubrication, alignment checks, and part replacements, helps extend the pump’s lifespan and ensures its reliability when needed most.

As a fixed fire-fighting equipment, the diesel engine fire-fighting pump set has been widely used in fire-fighting diversion, especially for fire-fighting water supply in unexpected situations such as no power supply or abnormal power supply (mains power).

EDJ fire pump set is composed of electric pump, diesel pump and stabilized pressure pump. In daily use, as an auxiliary pump, the stabilized pressure pump keeps the existence of liquid (water) in the fire pipeline at all times, and the electric pump works as the main power pump in normal work. When the circuit system is burnt out due to a serious fire, the diesel pump will start instead of the electric pump within ten seconds, which will not be affected by the circuit and complete the fire fighting work. In recent years, EDJ fire pump group has gradually become the first choice of fire protection systems in various office buildings and residential buildings, and its safety

Jockey pumps should be inspected regularly, with routine checks typically performed monthly. The inspection includes checking pressure settings, verifying proper operation, and inspecting for any leaks or damage. Ensuring that the jockey pump functions correctly helps maintain system pressure and prevent unnecessary wear on the fire pump.

Scope of application of fire pump set:
1. Industrial plants, automobiles, breweries, pulp and paper, chemicals, pharmaceuticals;

Firefighting pumps can be equipped with various accessories and add-ons to enhance their performance and versatility. Common accessories include foam proportioning systems for generating fire-suppressing foam, hose reels for convenient storage and deployment of hoses, suction strainers and filters for protecting the pump from debris, and pressure regulators for controlling the flow and pressure of water.

The EDJ series fire diesel electric fire pump unit (fire dual power pump unit) is based on the traditional fire protection system of GEM, which combines electric fire pump, booster regulator pump, diesel fire pump, regulator tank and supporting valves, Piping is combined on the same skid-mounted common base. The pump set can provide safety guarantee for fire emergency, and the diesel engine has the function of speed regulation, which makes the use and adjustment range of the unit equipment more extensive.

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.

Jockey pumps are a vital component in maintaining the pressure within a fire protection system. Their primary role is to keep the system’s pressure within the desired range. When there’s no fire event, the jockey pump operates to counteract any pressure losses due to minor leaks or gradual pressure decreases in the system.

By maintaining system pressure, jockey pumps ensure that the primary fire pump is ready to respond quickly and efficiently when a fire occurs. This pressure stability is crucial for the proper functioning of the entire fire protection system, allowing for immediate water flow to sprinklers or hose connections.

NFPA 20 requires fire pumps to be powered by a continuously available power source, usually identified as an uninterruptible power source. In many cases, this requirement requires a backup generator to be provided as a backup power source in the event of a power failure, in which case the fire pump controller must be equipped with an automatic transfer switch. The choice of fire pump depends on the building infrastructure and available space. The most common choices for fire pump drives are electric motors and diesel engines.

With the continuous progress of the times, the application of diesel engine fire pumps is becoming more and more extensive. Diesel engine fire pump is a common necessary facility. Only when the fire signal comes, and the electric water pump fails or the power supply is cut off, the diesel engine fire pump will automatically start. The diesel engine fire pump is installed together with the electrical instrument, with complete functions, compact structure, automatic fault alarm, accepting the starting signal, and can automatically complete the starting procedure and run at full load quickly. When the diesel engine fire pump is insufficient in fuel, low battery voltage, and high lubricating oil temperature , enough to ensure that the diesel engine fire pump starts in a low temperature environment, the entire system of the diesel engine fire pump is safe, reliable, and easy to use.

The fire pump is usually equipped with a local control cabinet. The control cabinet does not have a transfer control switch for automatic and manual conversion, but the automatic control loop leaves start and stop contacts, which are connected to the fire alarm system control module. In addition, according to the relevant regulations, the system using the bus linkage control should also be set in the fire control room with buttons that can directly start and stop the pump. When the fire alarm system receives the signal of the fire hydrant start pump button, the control module automatically starts the fire pump and collects its feedback signal.
