4. The diesel engine starts when the electric pump fails;

The product is EJ fire pump set. The EJ fire pump set has one electric pump and one jockey pump. The electric pump in the picture is ISW pump. ISW series horizontal single-stage single-suction centrifugal pump is a new generation of energy saving, environment friendly horizontal centrifugal pump researched and developed by our company, which absorbs advanced technology of similar products abroad and adopts domestic
general performance parameters of centrifugal pumps. In addition, according to different operation temperatures and mediums, we developed the hot-water pump (ISWR), corrosion-resistant chemical pump (ISWH) and oil pump (ISWB).

High-efficiency vertical in-line fire pumps offer stable water pressure, fast start-up, and high durability. They are compact and easy to install, making them suitable for high-rise buildings, factories, and large public facilities, ensuring reliable and safe fire emergency water supply.

The minimum fire rated pressure of ED small fire fighting package set water supply equipment is 3 bar and the minimum fire rated capacity is 25 GPM. ED small fire fighting package set water supply equipment includes at least two power or power source driven pumping units, pressure tanks, pipes, valves and accessories, measurement and control instruments, control cabinets, outdoor rain cover, etc.
Motor: Three-phase asynchronous squirrel-cage motor independently developed and manufactured by our company, which can be controlled in production time and greatly shorten the whole set production time.
Diesel Engine: According to the different parameters of customers, we will choose diesel engines with high cost performance ratio. The main brands are QuanChai, Weichai, ShangChai, FAWDE, Cummins, etc.
Electric Pumps: Electric pumps can use vertical in-line pumps, horizontal end-suction pumps, vertical multi-
stage pumps, horizontal multi-stage pumps, split casing pumps and so on according to the different flow and head of customers.
Diesel Pumps: Diesel pumps can use vertical in-line pumps, horizontal end-suction pumps, vertical multi-
stage pumps, horizontal multi-stage pumps, split casing pumps and so on according to the different flow and head of customers.
Electronic Components: The main electric components is CHNT, if Schneider or other brand electrical are need, should mention it before place the order.
Safety Valve plays a safety protection role in the system. When the system pressure exceeds the prescribed value, the safety valve opens, and a part of the gas/fluid in the system is discharged into the atmosphere/pipeline, so that the system pressure does not exceed the allowable value, so as to ensure that the system does not cause accidents due to excessive pressure.
Pressure Tank: Water is a non-compressible medium. Generally speaking, the pressure drop of fire-fighting pipe network is normal. However, the pressure drop is very slow, the total loss of water in the pipe network isnot large, and the frequent change of pressure in the pipe network leads to frequent start-up and shutdown of pumps. Especially when the power of equipment is high, it will cause great impact on pressure sensors, relaysand motors, thus affecting the performance and life whole equipment. Therefore, it is necessary to choose the right volume of the pressure tank.

Electric fire pump: It is an important part of the fire water supply system. Divided into ordinary type and foam type. The ordinary type is used for general fire water supply; the foam type is equipped with an adjustable proportion mixer and a cam pump, which can deliver the mixed liquid to various foam launching devices to extinguish various oil fires. The electric fire pump consists of two parts, the motor and the pump. The pump and the motor are coaxial. The pump structure includes pump body, rotor, pump cover, mechanical seal and other components.

It’s a customized EJ fire pump set consisting of electric pump, jockey pump along with control panel, and accessories. It is equipped with priming tank for doing negative suction.

The fire pump is a high-tech product, which is characterized by high efficiency, fast pumping speed, very strong sealing, and low leakage, which can also be said to be no leakage. The use of fire pumps is very extensive, of course, the most important one is used in the fire protection industry, it is also used in water treatment, environmental protection industry and so on. Among these uses, the fire protection industry uses the most. The fire protection industry makes full use of the advantages of fire pumps, which is the advantage of fast pumping. Because most of the work in the fire protection industry is to extinguish fires, the fire pump plays a very important role. Fire pumps are not just used in the firefighting industry. Fire pumps are also used in many other places. In larger industries, such as industry, as well as urban water supply and drainage, and water transportation for the construction of high-rise buildings, there is also water delivery over relatively long distances. There are also smaller industries, such as heating and boilers.

Fire pump system is made of Electric+Diesel+Jockey pump
Operation: 1 Duty (electric) + 1 standby (diesel engine) + 1 Jockey
Capacity: 100, 150, 200, 300, 400, 500, 750, 1000…GPM with pressure 4, 5, 6, 8, 10… Bar.
Pressure vessel 25, 50, 75, 100…liters, pressure will be 0.6mpa, 1.0mpa, 1.6mpa, select according to pump head.

1. Fire Pump: A fire pump is the heart of a fire sprinkler system and is used to create the necessary water pressure to make the system work. It is powered by an electric motor or diesel engine and pumps water from a water source to the sprinkler system.

2. Control Panel: The control panel is the brains of the fire sprinkler system. It controls the flow of power to the pump and monitors the sprinkler system for any changes in pressure or water flow. It also triggers alarms and other safety devices in the event of a fire.

3. Suction Pipe: The suction pipe is connected to the fire pump and draws water from the water source. It is usually made of steel and must be strong enough to withstand the pressure exerted by the pump.

4. Pressure Gauge: The pressure gauge is used to measure the pressure in the system and ensure that the pump is providing the correct amount of water pressure. It is usually mounted on the control panel.

5. Valves: Valves are used to control the flow of water to and from the system. They are typically operated manually or automatically and can be used to start and stop the pump, control the flow of water, and isolate parts of the system for maintenance.

The diesel engine fire pump is usually used as a backup facility, so it will only start automatically when the fire signal comes, and when the electric water pump fails or the power supply is cut off. When it has a device for starting the pump at ultra-low pressure, its matching electric water pump control cabinet should also have a device for starting the pump at ultra-low pressure, and the lower limit of the two pumps should have a certain pressure difference.

The EJ (Electric pump + Jockey pump) Dual Power Fire Pump System is an innovative and reliable fire protection solution. Combining an electric pump for robust water pressure and flow with a top-quality jockey pump for stable pressure maintenance, this system ensures efficient and timely water supply during fires. With advanced automation, remote monitoring, and energy-saving features, the EJ Dual Power Fire Pump System is a trusted choice for commercial, industrial, and residential applications.
