Electric fire pumps are driven by electric motors, and are divided into horizontal, vertical and many other structural varieties. The electric fire pump set has a small footprint, light weight, low noise, and good start-up and operation performance. Although electric fire pumps have the advantages of simple operation and maintenance, most fire protection system design specifications stipulate that when electric fire pumps are used, they should have the conditions for dual-circuit power supply, and diesel engine fire pumps are usually used as backup pumps.

Features of diesel multi-stage pump:
1. Multiple impellers are combined in series, the output pressure is large, so the lift is high.
2. The shaft seal adopts packing seal or mechanical seal, the seal is safe and reliable, the structure is simple, and the maintenance is convenient and quick.
3. The shaft is a fully sealed structure, which ensures no contact with the medium, no rust, and long service life.

1. Manual Operation: This method involves manually operating the fire pump by an operator who is trained to handle it.

2. Automatic Operation: This method uses an automatic sensing and control system to start and stop the fire pump when needed.

3. Pressure Control: This method uses a pressure switch to monitor the pressure in the system and activate the fire pump when necessary.

4. Flow Control: This method uses a flow switch to monitor the flow in the system and activate the fire pump when necessary.

5. Variable Frequency Drives (VFDs): This method uses a VFD to provide precise control over the speed and torque of the fire pump. This helps to ensure that the fire pump is operating optimally.

6. Remote Monitoring: This method uses a remote monitoring system to provide real-time data on the condition of the fire pump and to allow for remote operation if necessary.

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.

Fire pump test headers allow for the controlled flow of water during routine testing. They are used to verify the performance of the pump, pressure switches, and other components, providing a standardized method for testing without affecting the main fire protection system.

What is Water Hammer?
A sudden increase in water pressure caused by rapid valve closure or pump shutdown, leading to:

Pipe vibrations and damage.
Pressure surges that can exceed system limits.
Component wear and potential pump failure.
Prevention Methods:
Use slow-closing valves to prevent sudden pressure changes.
Install surge arrestors or expansion tanks to absorb pressure spikes.
Ensure proper pump start/stop sequences to reduce shock loads.

Handling such systems involves:

Zoning: Implement zoned fire protection systems tailored to the specific needs of different areas within the building, such as residential, commercial, and industrial spaces.
Custom Design: Design custom fire pump setups to meet the diverse requirements of each zone, ensuring adequate pressure and flow rates.
Flexible Operation: Use control systems that allow flexible operation and adaptation to the varying fire protection needs of different building areas.
Unified Monitoring: Integrate the fire pump systems into a unified monitoring and control system to ensure coordinated response and management across the entire building.

Yes, fire pumps can operate in high-altitude locations, but their performance may be affected due to reduced atmospheric pressure, which can impact water flow and engine performance. It’s essential to select pumps specifically designed or adjusted for high-altitude use, ensuring they meet the required pressure and flow rates.

Fire pumps are part of the applied water supply and are powered by electricity, diesel. They activate when the pressure in the fire sprinkler system drops below a certain level and provide a flow of water to the sprinkler system at very high pressure, which is then discharged onto the fire.

Fire pump installations in historical buildings may have unique considerations to preserve the architectural integrity. Compliance with historical preservation guidelines and coordination with relevant authorities is crucial.

Diesel engine fire pump is a common and necessary facility. Only when the fire signal comes, and the electric water pump fails or the power supply is cut off, the diesel engine fire pump will automatically start. Diesel engine fire pump is installed together with electrical instruments, with complete functions, compact structure, automatic fault alarm, receiving start signal, and can automatically complete the start-up procedure and fast full-load operation. , Enough to ensure that the diesel engine fire pump is started in a low temperature environment, the whole system of the diesel engine fire pump is safe, reliable, and easy to use.

The outdoor fire pump set has significant advantages such as high efficiency, low operating noise, good cavitation resistance, reasonable structure and long service life. , long-distance water supply, heating, bathroom, boiler hot and cold water circulation pressurization, air conditioning refrigeration system water supply and equipment matching and other occasions.

This is a set of EDJ fire pump set, which consists of electric pump + diesel pump + jockey pump. The three pumps are automatically started and stopped. When the joceky 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.

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.

There are many types of fire pumps to deal with more fire water environments. Fire pumps are used in buildings, factories, storage and other places, and the performance requirements and quality requirements are different. The commonly used types of fire pumps are vertical electric fire pumps, diesel fire pumps, horizontal single-stage fire pumps, vertical single-stage/multiple Level fire pumps and horizontal double-suction fire pumps, etc., the specific head, flow and power are selected according to different projects.

The dual power fire pump is composed of a fire water pump, a double shaft extension motor and a diesel engine. One end of the output shaft of the double shaft extension motor is connected to the input shaft of the fire pump, and the other end of the output shaft of the double shaft extension motor is One end of a clutch is connected, and the other end of the clutch is connected with the output shaft of the diesel engine. The fire water pump, the double-shaft extension motor, the clutch and the diesel engine are all fixed on the base. The double shaft extension motor, the clutch and the diesel engine are respectively electrically connected with a control circuit through an action driving circuit. With dual-power fire pumps, there is no need to configure a second fire pump, which reduces floor space and saves manufacturing costs.

Fire pumps are part of the water supply to a fire sprinkler system and are powered by electricity, diesel or steam. The pump inlet is either connected to a public groundwater supply or to a static water source (e.g. tank, reservoir, lake).

The diesel pump + jockey pump can be started normally in case of power failure. Jockey pump ensures the presence of liquid in the fire pipeline. When a fire occurs, the diesel pump starts to work within ten seconds to control the fire.

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 position of the electric fire pump.
