Local building codes dictate specific requirements for fire pump installation, including minimum flow and pressure, power supply standards, and room construction. Compliance with these codes is essential for the system’s approval and operation.

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.

The jockey pump of the jockey fire water supply system must be kept running at ordinary times to maintain the pressure of the pipe network. When a fire occurs, it should still be able to run for a period of time until the main fire pump is started. It must be set according to the main and standby pumps. pressure pump. Due to the need for the stabilizing pump to keep running, energy is wasted, and the stabilizing pump is in working condition for a long time.

Safety Valve plays a safety protection role in the system. When the system pressure exceeds the prescribed value, the safety valve opens, and a part of the gas/fluid in the system is discharged into the atmosphere/pipeline, so that the system pressure does not exceed the allowable value, so as to ensure that the system does not cause accidents due to excessive pressure.
Pressure Tank: Water is a non-compressible medium. Generally speaking, the pressure drop of fire-fighting pipe network is normal. However, the pressure drop is very slow, the total loss of water in the pipe network isnot large, and the frequent change of pressure in the pipe network leads to frequent start-up and shutdown of pumps. Especially when the power of equipment is high, it will cause great impact on pressure sensors, relaysand motors, thus affecting the performance and life whole equipment. Therefore, it is necessary to choose the right volume of the pressure tank.

When selecting a firefighting pump, it’s essential to consider factors such as the type and size of fires likely to be encountered, the terrain and accessibility of the area, the availability of water sources, and the expertise of the operators. For example, wildland firefighting may require lightweight and portable pumps capable of drawing water from remote sources, while industrial settings may require high-capacity pumps with specialized features for handling flammable liquids or chemicals.

In the fire fighting pipeline pump, according to the different installation methods can be divided into vertical fire pumps and horizontal fire pumps, many people have questions about these two common pumps, what is the difference between the two? Shanghai Xizhiquan will explain the difference between horizontal and vertical pumps.

Obviously, different installation methods take up different space. Vertical pipeline pumps are installed vertically, covering a relatively small area, and vertical fire pumps do not require a foundation, while horizontal fire pumps need to be equipped with a base.

According to the different structures of the two pumps, it can be concluded that there is also a certain difference in the ease of maintenance of the two types of fire fighting pipeline pumps. The impeller of the vertical fire pump needs to be dismantled from top to bottom, which makes maintenance more difficult; the horizontal fire pump only needs to have the inlet pipe removed so that the impeller can be overhauled, which is relatively simple.

Due to the different inlet and outlet pipe directions, the pipeline connection between vertical and horizontal is also different. As the vertical pump is a bottom-up structure, while the horizontal fire pump is longitudinally arranged on the base, so the motor of the vertical pump and the pump body are connected in the form of sub-mouth connection, while the horizontal pump needs to use couplings to connect with the motor, and the horizontal pipeline pump needs to be corrected regularly.
