Assembled EDJ Fire Pump

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.

1. Connection form

The vertical water pump is connected with the motor by the coupling, which needs to be aligned regularly; the perpendicular water pump is superimposed and connected from the bottom to the top, and the perpendicular water pump is generally called the channel pump.

2. Installation form

Compared with perpendicular water pumps, perpendicular water pumps are easier to install. The vertical pump set is handed with a base, and perfection adaptation is needed after installation.

3. conservation difficulty

Since the perpendicular water pump is composed of upper and lower layers, the conservation of the perpendicular water pump is more delicate. For illustration, to repair the impeller, it’s necessary to remove all the corridor above the impeller before repairing; while the vertical water pump is fairly easy. For illustration, the IS type pump can perform impeller conservation by removing the bay pipe.

4. bottom space

It can be seen from the appearance that the vertical water pump has a base due to its vertical structure, so it occupies a large area.

Yes, various national and local codes and standards, such as NFPA 20 (Standard for the Installation of Stationary Pumps for Fire Protection), provide guidelines for the installation, operation, and maintenance of fire pumps.

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.

Fire pumps should be tested on a regular basis according to national and local regulations. Common testing frequencies are monthly, quarterly, annually, and five-yearly, with different tests conducted at each interval.

The application of electric fire pumps is not only in fire protection systems, but a variety of fire pumps are gradually showing their superior strength in industrial production and urban construction. This includes the implementation and expansion of high-end technologies for industrial and urban water supply and drainage, and high-rise building underpressure water delivery.

The EJ model is basically a combination of an electric drive and a jockey pump. They consist primarily of an end suction pump driven by an electric motor, with no backup pump. It is also combined with a jockey pump for maintenance to form a complete skid.

The complete EJ-style skid is assembled with all discharge line accessories and connected to the skid-mounted control panel.

Diesel engine fire pumps are suitable for use in high lift and high flow fire water supply environments or as backup fire water supply pumps. The reason is that the diesel engine has strong power and can be used with large flow fire deep well pumps, and the diesel engine fire pumps have the characteristics of self-starting when power is off. Emergency water supply is available, so a diesel engine fire pump is a good choice.

A fire pump package set is often quicker to install and is ideal for specific applications, while an integrated fire system can offer more comprehensive fire protection. The best option depends on your facility’s specific requirements, layout, and risk factors.

All places need to be equipped with fire-fighting facilities, and fire pumps are necessary water intake equipment for fire-fighting facilities. At least one or two fire pumps are equipped. The fire pumps we commonly use are electric fire pumps and diesel engine fire pumps. The difference between the two is The electric fire pump needs to be supplied by the power system. If the power is cut off, the diesel engine fire pump can be started at any time to make up for the original position of the electric fire pump.

Diesel engine fire pump, as a fixed fire extinguishing equipment, has been widely used in fire diversion, especially in emergencies such as no power supply or abnormal power supply, it can also be equipped with other diesel engines as power engines according to the needs of users.
