The conventional electric pump is the main pump, the diesel engine pump is the backup pump, and the voltage stabilizer pump plays a role in the stabilization of the whole system. When the electric pump fails or the mains is cut off, the control cabinet will receive the pressure gauge from the electric contact. When the signal comes, the diesel engine pump will be started within 5 seconds, and the rated working condition will be reached within 20 seconds to ensure the normal operation of the fire extinguishing work.

High-performance diesel fire pumps, featuring high-temperature and corrosion resistance, are suitable for industrial plants, chemical bases, power plants, and high-rise buildings. Their independent diesel powertrain ensures stable water supply even in power outages, while their intelligent control system enables automatic start-up and remote monitoring. With their robust construction, easy maintenance, and efficient and reliable operation, they provide a robust and safe emergency water supply solution for various firefighting projects.

Diesel fire pumps, with their independent energy supply, rapid response, high pressure and large flow, durable structure and intelligent control, demonstrate extreme reliability in high-risk locations such as petrochemical plants, mines, tunnels and airports, ensuring stable water supply at critical moments and building a safety barrier for life and property.

In high-rise buildings, fire pumps and jockey pumps are critical components of the fire protection system, ensuring that water is delivered to the upper floors with sufficient pressure. Due to the height of these buildings, gravity significantly reduces water pressure as it travels upwards, making it essential for fire pumps to boost pressure to maintain effective firefighting capabilities. Jockey pumps maintain system pressure in between fire pump activations, compensating for minor leaks and ensuring the system is always primed. The design of these pumps in high-rise buildings often includes considerations for redundancy, with multiple pumps and backup power supplies to ensure continuous operation even during power outages or pump failures. This redundancy is vital in high-rise buildings, where a delay or failure in water delivery could have catastrophic consequences.

EDJ series fire pump set consists of electric pump + diesel pump + jockey pump and all accessories.
The three pumps are automatically started and stopped. When the jockey pump detects that the electric pump cannot operate normally, the diesel engine pump will start automatically. Can also be used, the fire pump set is widely used in various emergency firefighting occasions.

What kind of terrain to choose what kind of water pump

This problem, in short, is the selection of water pumps. The following are the applicable way for you to choose water pumps from zjbetter. I hope they can help you choose water pumps and help you better. Choose the water pump that suits your design.
1. Confirm the use terrain
First understand the terrain in which the outfit is used, including temperature, moisture, air pressure, air cattiness, dustproof and leakproof conditions, and the position of dangerous areas.
2. Confirm operating conditions
Refers to the liquid face pressure( absolute) on the suction side of the liquid, the liquid face pressure on the discharge side, intermittent or nonstop work, fixed or mobile position, and the convenience of installation and conservation.
3. Confirm the nature of the medium
Medium temperature, viscosity, density, impregnated vapor pressure, solid flyspeck periphery and content, gas content, cattiness, volatility, trap, toxin.
4. elect the material of the pump bathe corridor
According to the physical and chemical parcels of the pumped medium above, the material of the inflow- passing corridor is determined.
5. Determine performance parameters
The performance parameters of the water pump can be determined by computation, analogy, test and other styles.
6. Determine the installation type
The installation of the channel is determined by the layout of the channel and the installation point, and there are direct connection, perpendicular and other types.
8. Determine the number of pumps
In general, spare pumps, especially fire pumps, are set up, and the number of pumps is named according to different situations.

Electric fire pumps are widely used in our production and life, such as in water treatment, fire safety and other departments. After the reform and opening up, it is widely used in life and production due to its characteristics of complete sealing, no leakage, and corrosion resistance.

Learn how to diagnose and fix common issues when your fire pump fails to start.

The use of fire pumps is generally based on different situations. Different types will have different classification methods. The fire pump is in its own fully sealed state, without the possibility of leakage, and can resist corrosion. , is widely used, and is mainly used in fire protection, sewage treatment and some departments of environmental protection. It is used to pump different liquids, so that there is no leakage and no pollution. It is very civilized A kind of fire engine, which is very beneficial to the use of all of us.

In cold climates or areas prone to extreme weather, fire pumps face unique operational challenges that require careful design and maintenance. Freezing temperatures can cause water to freeze in the pipes, potentially damaging the fire pump and other components of the fire suppression system. To mitigate this, fire pumps may be installed in heated enclosures, and antifreeze solutions or dry-pipe systems are often used to prevent freezing. Jockey pumps help maintain system pressure, but in extreme weather, they must be monitored closely to ensure they don’t overcompensate for changes in pressure caused by temperature fluctuations. High winds, flooding, or snow accumulation can also impact the performance of fire pumps, especially in outdoor or exposed installations. Ensuring that fire pumps have robust weather protection, backup power supplies, and regular winterization procedures is critical for maintaining their reliability in harsh conditions. Additionally, these pumps should be designed with durable, weather-resistant materials to withstand long-term exposure to extreme environmental factors while still delivering dependable fire protection.

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. Our commonly used fire pumps 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 electric fire pump.
