The fire booster pump is designed to increase the flow and pressure rate of the water supply coming into the fire system. This is accomplished by drawing water from a municipality main, tank, or hydrant, and then boosting the pressure rate of the water supply with an electric motor and pump. The adjusting of the pressure rate is accomplished by changing the speed of the electric motor that is powering the pump, which in turn changes the amount of water being pushed through the system.

Fire pumps can encounter various issues that affect their performance. This article provides an in-depth guide to troubleshooting common problems, including cavitation, air binding, and leaks. It offers step-by-step solutions and preventive measures to address these issues and maintain reliable fire pump operations.

The diesel engine (can be equipped with a clutch) is combined with the fire pump through a highly elastic coupling to form a fire pump unit. The unit also includes diesel tanks, cooling water tanks, fans, control panels (for automatic units) and other components.
When the unit is automatically controlled, the split or diesel engine automatic control cabinet (programmable) realizes the automatic start, input, and automatic switching of the system (switching from the electric pump group to the diesel engine pump group or from this group of diesel engine pump groups to another group of diesel engines) pump set), automatic protection (diesel engine overspeed, low oil pressure, high water temperature, three start failures, low oil level, low battery voltage and other alarm shutdown protection) and other functions, and can also interface with the user’s fire center or automatic fire alarm device, Realize remote monitoring.

The double-suction fire pump has the characteristics of high lift and large flow, and is widely used in fire fighting. The impeller of this pump type is actually a combination of two back-to-back impellers, and the water flow from the impellers merges into a volute. The double-suction pump has the following characteristics: it is equivalent to two single-suction impellers of the same diameter working at the same time, and the flow rate can be doubled under the same outer diameter of the impeller; the pump casing is horizontally opened, which is convenient for inspection and maintenance. The inlet and outlet of the suction pump are in the same direction and perpendicular to the pump shaft, which is conducive to the arrangement and installation of the pump and the inlet and outlet pipes; the impeller structure of the double suction pump is symmetrical, there is no axial force, and the operation is relatively stable.

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.

The pump and the motor are coaxial, which simplifies the connection of the pipeline. The pump inlet and outlet are on the same horizontal axis, and the diameter and specifications are the same. The pump is provided with a mounting base, which is easy to install and increases the stability of the pump operation. The pump seal adopts mechanical seal, which has the characteristics of reliable sealing and no leakage.

CDL stainless steel vertical multistage pump has the remarkable characteristics of small size, light weight, high efficiency, energy saving, low vibration and noise, smooth operation, long service life, vertical installation, small footprint, light weight and beautiful appearance.

According to the needs of system operation control and maintenance management, the fire pump electrical control cabinet mainly has the functions of starting and stopping the pump, switching the main and standby pumps, manual automatic switching, dual power switching, inspection, protection, and feedback mechanical emergency start.

Firefighting pumps are often integrated with other firefighting equipment and systems, such as fire hoses, fire hydrants, sprinkler systems, and fire suppression systems. This integration ensures a coordinated and comprehensive approach to fire protection and emergency response, enabling firefighters to work together seamlessly to combat fires and protect communities.

There are many applications for fire pumps. Different motors are selected according to the flow rate and head size. The commonly used motors include electric motors and diesel engines, and domestic and foreign brands can match the application. The fire pump can choose vertical or horizontal structure according to the pipeline requirements, and the head size is also different. Finding a professional pump factory or company can reduce the probability of wrong selection, and at the same time take into account the on-site installation requirements and pipeline design.

1. When installing the water inlet pipe, the horizontal section should be horizontal or upward
2. There are many elbows used on the water inlet pipe
3. The water inlet of the water pump is directly connected with the elbow
4. The last section of the water inlet pipe equipped with a bottom valve is not vertical
5. The position of the water inlet of the water inlet pipe is wrong
6. The outlet pipe is above the normal water level of the outlet pool

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.

The engine cooling system of the diesel engine fire pump adopts double closed-loop heat exchangers. The system has the advantages of high cooling efficiency and little impact on the ambient temperature of the pump room. The cooling water flow direction is controlled by a ball valve from the pump outlet pipe to the heat exchanger, so that the cooling water temperature of the machine body is between 85 and 95 °C. If the water temperature is too high, you can increase the opening of the ball valve, increase the heat dissipation capacity of the heat exchanger, and reduce the temperature of the engine cooling water.
