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

The fire pump set is composed of a diesel fire pump and an electric fire pump. The pump set is a horizontal, single-suction, single-stage centrifugal pump. It has the characteristics of high efficiency, wide range of performance, safe and stable operation, low noise, long life, convenient installation and maintenance, etc. It is used to transport clear water or other liquids whose physical and chemical properties are similar to water. It can also be used to transport hot water, oil, corrosive or abrasive media by changing the material of the pump’s flow parts, sealing form and adding a cooling system.

Floating impeller axial force tone- balancing device
The balancing slice device has two gaps, the radial gap behind the impeller and the axial gap of the balancing slice, because of these two gaps, the balancing slice can automatically acclimate the axial l gap to achieve automatic balance of axial force, and the tableware rotor is in a floating state.

The principle of the balance plate is scattered to the impeller, the impeller back mouth ring radial concurrence below the axial concurrence, this device that’s the same as the balance plate, the conformation of two gaps, only in a different position. Because the impeller has these two gaps to round each other, so that the impeller can also achieve automatic balance of axial forces.

All accessories of EJ small fire complete water supply equipment are assembled according to the standard (NFPA20). Its configuration depends on the customer’s needs, or the number of pumps and the type of electric pump. EJ small fire pump group consists of electric pump and jockey pump. EJ small fire-fighting complete set of water supply equipment has reasonable layout, firm installation, reliable connection, compact structure, neatness and convenient maintenance.

In fire protection systems, various types of fire pumps are used. Fire pumps are classified as horizontal split case, vertical split case, vertical in-line, vertical turbine, or end suction. These fire pumps may be powered by an electric motor, a diesel engine, or on rare occasion powered by a steam turbine.

Speed:2950-3550RPM

Diesel engine fire pump sets are mainly suitable for fire water supply and foam fire extinguishing systems in petrochemical, natural gas, power generation, cotton and linen textiles, warehouses, airports, docks, high-rise buildings and other industries. It can also be used in occasions such as water ships, offshore oil tankers and fire fighting ships. The unit adopts imported diesel engine and fire pump. It has the characteristics of quick start, reliable water diversion, reasonable power reserve, stable operation, high degree of “three modernizations”, wide range of pressure and flow, etc. It is an advanced and reliable fire-fighting equipment.

The two main starting and control methods for fire pumps are manual starting and automatic starting.

Manual Starting: Manual starting is the simplest and most commonly used method for starting a fire pump. It involves the use of a manual start switch or lever to start the pump motor.

Automatic Starting: Automatic starting is the most reliable method for starting a fire pump. It involves the use of a control panel, which can be programmed to start the pump motor when a drop in pressure is detected. The control panel also monitors the pump’s performance and can be used to shut off the pump if it fails to start or is not performing properly.

Safety precautions include de-energizing electrical systems before maintenance, providing proper ventilation in pump rooms, and following lockout/tagout procedures to prevent accidental startup.

Diesel engine fire pumps are suitable for use in fire water supply environments with high head and high flow rate 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 diesel engine fire pumps are favored.

1. Choose a fire pump with good performance and reliable quality.

2. The fire pump should be suitable for the working pressure and flow rate required by the fire fighting system.

3. Pay attention to the safety performance, reliability and stability of the fire pump.

4. Check whether the fire pump meets the requirements of the relevant national standards.

5. Pay attention to the after-sales service of the fire pump manufacturer.

6. Consider the cost performance of the fire pump.

7. Choose a fire pump from a qualified manufacturer.

The fire pumps used in diesel engine fire pump sets can be IS series single-stage type, S, D type series segmental multi-stage type produced by our company. The diesel engines used in this series of equipment are domestic or imported high-quality products, which have the characteristics of good starting characteristics, strong overload capacity, compact structure, convenient maintenance, simple use, and high degree of automation. It is an advanced and reliable fire-fighting equipment.

DJ series fire pump set consists of Diesel pump + Jockey pump and all accessories.
The pressure switch and control cabinet can automatically turn on/off three pumps-the electric pump and jockey pump operate when there is electricity and the diesel pump activates when the power cuts.

XBC diesel engine fire pump set is the latest according to the national standard GB6245-2006 “fire pump performance requirements and test methods”. This series of products has a wide range of lift and flow, and can fully meet the fire water supply in various occasions such as warehouses, docks, airports, petrochemicals, power plants, liquefied gas stations, textiles and other industrial and mining enterprises.

What are the components of the fire pump group
1. Electric pumps: various end suction pumps and split case pump.
2. Jockey pump: vertical, small flow, head higher than electric pump or diesel pump.
3. Control panel: Automatically control the water pump, with overload and overcurrent protection functions.
4. Accessories: suction pipe, discharge pipe with flange, battery, gate valve, check valve, expansion joint, pressure switch, pressure gauge, base, etc.

Water hammer in fire pump systems with high flow rates is mitigated by incorporating surge suppressors, check valves, and properly designed piping configurations. These measures prevent sudden pressure changes and protect pump components.

The pump head of this fire pump set adopts ISW pump, which has the advantages of convenient installation and competitive price. Its performance parameters and technical indicators meet relevant standards, and it has the characteristics of high efficiency and reasonable structure.

When the fire pump is in operation, if the power supply of the motor fire pump power supply is turned off or the electric pump fails to start normally, the diesel engine fire pump will automatically start and run. During normal operation, there is a fully automatic switchover to an electric pump.

The advantage of its product is that when a fire occurs, the power supply fails, and the electric fire pump set cannot be put into use normally, the diesel engine fire pump set can be put into operation automatically to ensure the normal fire fighting. Compared with the electric fire pump set, it does not need long-term investment in power supply, saving the mains power supply transformer and normal expenses. Diesel engine fire pumps are equipped with various automatic functions to meet customer requirements, ensure long-term normal standby status of the equipment, and put it into fire fighting work at any time. The diesel engine fire pump set is also suitable for various emergency backup pump occasions.

A fire pump is a device that increases water pressure for fire protection systems, while a fire hydrant is an external water supply point for firefighters to connect hoses. Fire pumps are often used within buildings, while fire hydrants are located externally for access by firefighting teams.
