Deep Well Fire Pump

Core basic functions:

Using deep wells and groundwater as water sources, it achieves high-pressure, stable, and continuous fire-fighting water supply to meet the fire-fighting water needs at fire scenes.

Specialized functionsEmergency Activation: 

It supports three activation modes: automatic, manual, and emergency, and provides rapid water supply response in case of fire.

Deep well water extraction:

It is compatible with deep well water sources and achieves stable operation of the underwater pump body through long shaft drive, eliminating the need for ground water storage facilities.

Pressure-stabilized water supply: 

It can be used in conjunction with fire-fighting pressure stabilization systems to achieve daily pressure stabilization and water replenishment in the pipeline network, ensuring stable system pressure.

Continuous operation:

It meets the long-term operational requirements of fire-fighting equipment and continuously provides high-pressure fire-fighting water during the duration of a fire.

1. Water source environment: The source of water is groundwater such as deep wells, groundwater, and water wells; the medium is clean water, free of obvious impurities and corrosive substances, and the particle size of solid particles is <0.5mm.

2. Installation environment: Vertical deep well installation, with the motor placed in a ventilated area on the ground and the pump body submerged underwater; suitable for deep wells with a diameter ≥ pump body diameter + 100mm, and the installation depth can be customized according to the length of the drive shaft.

3. Temperature environment: Medium temperature 0℃~40℃, ambient temperature -10℃~50℃; the motor operating environment must be ventilated, dry, and free from high-temperature heat sources.

4. Electrical environment: Protection rating: Motor IP55 (ground), pump body IP68 (underwater); Insulation class: F; Compatible with three-phase 380V/440V power supply, supports emergency power supply connection.

5. Operating environment: It supports long-term intermittent operation and can operate continuously and stably in emergency situations; it is compatible with the automatic/manual/emergency start-up conditions of fire protection systems; and it must meet the anti-interference and rapid response requirements of the fire protection industry.

1. Specifically designed for deep wells, with strong adaptability to various water sources. 

Designed specifically for deep wells and groundwater, it eliminates the need for surface water storage facilities, solving the problem of fire-fighting water supply from underground water sources.

2. Rapid activation and timely emergency response. 

It supports three activation modes: automatic, manual, and emergency, meeting the rapid response requirements of fire protection systems and providing immediate water supply in the event of a fire.

3. Reliable operation and stable and continuous water supply. 

The long shaft drive structure is stable and can operate continuously in emergency situations, ensuring a high-pressure, continuous supply of fire-fighting water.

4. Flexible installation and wide compatibility

The motor is installed on the ground, the pump body operates underwater, the length of the drive shaft can be customized to adapt to different well depths, and the installation is convenient.

1. Fire water supply for high-rise buildings 

Indoor and outdoor fire-fighting water supply systems that use deep wells as a water source for residential communities, office buildings, hotels, commercial complexes, etc.

2. Fire protection systems for industrial and mining enterprises 

Firefighting and emergency water supply in production areas using deep well water sources, such as factories, mines, smelters, and chemical plants.

3. Fire safety protection for warehousing and logistics

Large warehouses, logistics parks, cold chain bases, etc., use deep well water sources for fire sprinkler and fire hydrant systems.

4. Fire protection for municipal public facilities 

Fire emergency water supply systems using deep well water sources in remote areas such as parks, scenic spots, train stations, and airports.

5. Firefighting in rural and remote areas 

Township residential areas, rural factories, and remote farms, which lack municipal water supply and rely solely on deep well water for their fire-fighting systems.

6. Fire safety backup for special locations 

Data centers, power facilities, and important security units use deep well water sources as backup fire-fighting pressure-stabilizing water supply systems.

1. Before powering on: Check that the water level is submerged, the power supply is switched, the shaft is not stuck, and the valve is in position.

2. Running: It features automatic, manual, and emergency start-up modes, monitors current and pressure, and continues to operate in emergency situations.

3. After shutdown: For normal shutdown, close the valve first and then disconnect the power; for emergency shutdown in case of malfunction; for long-term shutdown, disconnect the power supply and take protective measures.

1. No pressure upon startup, unable to supply water. 

2. Automatic start function malfunction. 

3. Vibration or abnormal noise from the drive shaft. 

4. Motor overload or over-temperature tripping. 

5. Flow rate and head not reaching rated values. 

6. Dual power supply switching failure. 

7. Water leakage at sealing points. 

8. Bearing wear and jamming. 

9. Impeller scaling or blockage. 

10. Aging or poor contact in the cable.
