If you are an owner, building manager, installation contractor or safety consultant in Tehran, you probably know that the "Fire Pump Booster" is the heart of the water supply fire extinguishing network, and its correct operation can make the difference between controlling an incident and spreading it at the moment of crisis. On the other hand, Tehran, with its high-rise buildings, population density, urban water network pressure limits and variety of uses, has turned the design and installation of fire booster pump into a completely specialized work. In this article, in a practical way and according to the approaches of fire fighting standards, we explain the steps of designing and installing a fire booster pump in Tehran, we check the common errors and we tell the criteria for choosing a contractor and equipment so that you can finally have a reliable, verifiable and reliable system. In the end, we explain why "Superior Smart" can be a professional choice for the design, supply, installation and commissioning of your fire pump booster.

What is a fire pump booster and why is it vital in Tehran?

Fire pump booster is a set of pumps, control panel, collectors, valves, precision instruments and peripheral equipment, which is designed with the aim of providing the required flow and pressure of the fire extinguishing system (hydrant, riser, fire box, sprinkler and various combinations) in a stable and reliable manner. In many projects in Tehran, the city water pressure is not enough to reach the upper floors or supply several points of consumption at the time of fire, so the fire pump booster must be designed to provide the required flow and pressure in the worst case scenario. The important thing is that the fire pump booster is different from the normal water supply pump booster, and the fire extinguishing standards define specific requirements for it in the field of reliability, redundancy, power supply, automatic control, testability and maintenance.

Fire fighting standards and key requirements in fire pump booster design

When we talk about fire pump booster design according to firefighting standards, it means that the system is compatible with safety and performance criteria, from the stage of calculations to the selection of equipment and the implementation of installation. Depending on the type of project and the approval authority, international standards such as NFPA or internal reference standards and guidelines of the fire department and regulatory authorities may be cited. The most important requirements that must be met in any case include the following: having a main pump with adequate capacity, using a reserve or redundant pump to increase reliability, the presence of a jockey pump to compensate for leaks and maintain network pressure without turning on and off the main pump, the possibility of periodic testing without disrupting the service, choosing the appropriate control panel with the correct protections and working modes, providing emergency power or predicting a power outage scenario, complying with the standard in piping, collectors, valves, and earthquakes. and connections, and finally commissioning and delivery by recording test results and user training. In Tehran, in addition to firefighting standards, executive conditions such as engine room space limitations, ventilation, access for repairs and acoustic requirements should also be considered in the design.

Stages of fire pump booster design in Tehran from needs assessment to calculations

The design of the fire pump booster should begin with a detailed knowledge of the project. The type of building use (residential, office, commercial, medical, industrial), height and number of floors, type of fire extinguishing system (sprinkler, hydrant, fire box, combined), number of zones, fire risk and approval authority requirements, all determine the required flow rate and pressure. In the calculation phase, the design scenario is first selected; For example, the simultaneous operation of a certain number of fire extinguishers or the activation of a certain zone of sprinklers along with the hydrant needs. Then the pressure drop of the paths is calculated: the drop in risers, branches, valves, filters, fittings, as well as the static height difference. The result of these calculations makes the required performance curve based on which the pump is selected. In Tehran, due to the difference in water network pressure in different areas and hourly changes, a more conservative design is usually recommended so that the fire pump booster can be responsive in low network pressure conditions. In addition, the selection of the water storage tank and its volume according to firefighting requirements and expected support time is an integral part of the design.

Selection of main components: main pump, reserve pump and jockey pump

A standard fire pump booster usually consists of a main pump, a reserve pump and a jockey pump. The main pump is responsible for providing the main flow and pressure and must be selected exactly according to the designed work curve. The reserve pump is considered to be of equal or close capacity to the main pump so that if the main pump fails or is not in service, the system will still maintain the fire extinguishing function. A jockey pump is a smaller pump that is used to compensate for minor pressure drops caused by leaks or small changes in the network so that the main pump does not turn on unnecessarily; This increases the life of the main pump and prevents pressure fluctuations. In choosing all three pumps, quality of construction, type of sealing, efficiency, ability to supply parts, and compatibility with operating conditions in Tehran are very important. Professional teams such as "Top Smart" usually do not select the pump based on the power number alone, but carefully examine the pump curve, operating point, NPSH, suction conditions, and the risk of cavitation so that the fire booster pump does not fail during a fire.

Fire pump booster control and automation panel

In fire fighting standards, the control panel plays a very important role in ensuring that the pumps are turned on in time and correctly. The panel must be able to receive the start command from pressure switches or transmitters, manage the priority of turning on the pumps, announce the status of errors, and provide the possibility of manual and automatic control. It should also be possible to periodically test and record situations. One of the common errors in Tehran is the installation of non-specialized panels or inappropriate settings, which causes unnecessary starts, delays in starting or even no start in real pressure drop conditions. In the projects that "Top Smart" implements, there is usually a special emphasis on choosing a switchboard with proper protective equipment, standard wiring, labeling, and fine-tuning of setpoints so that the fire pump booster will work at the moment of need without depending on the operator.

Important points in installing fire pump booster in Tehran

Fire pump booster installation is not just putting pumps in the engine room; Standard installation includes correct placement, implementation of suction and heat piping with technical principles, installation of suitable valves, prediction of seismic and standard support, provision of ventilation and service access, and correct implementation of cabling and earthing. In Tehran, due to the limitation of engine room space in many buildings, choosing the right arrangement of collectors and how to place the pumps is doubly important. The suction line should be as short as possible, with minimal bends and pressure drop, and avoid unventilated spots. The use of a suitable one-way valve, an accessible shut-off valve, pressure gauges, and, if needed, a flowmeter or a flow test site, helps the operation and testability of the system. Also, the correct installation of the jockey pump and its pressure settings should be such that the pressure range of the network is kept stable. The implementation of these details in the installation of a fire booster pump makes the difference between a verifiable system and a high-risk system.

Testing and Commissioning: The phase that determines true quality

Even the best fire pump booster design is not reliable in practice if it is not properly tested and started. During the start-up phase, the performance of each pump should be checked individually, the rotation direction should be controlled, cut-off and connection pressures and set points should be adjusted, leaks should be fixed, and performance tests should be performed according to the design scenario. It is better to test flow rate and pressure with reliable methods to determine if the system reaches the required flow rate at the actual working point. In many projects in Tehran, the lack of testability and the lack of registration of test reports cause serious problems during the inspection or renewal of approvals. By implementing the technical handover process, providing start-up documentation and training the building operator, "Superior Smart" will help your fire pump booster not only be installed, but truly ready for emergency use.

Periodic maintenance of fire pump booster and common mistakes

Fire pump booster is a safety equipment and its periodic maintenance should be taken seriously. Periodic testing of pumps, checking pressures, controlling leaks, checking the health of the one-way valve, the condition of vibrators, abnormal noise and vibration, the condition of the board and alarms, and checking the emergency power supply are essential. One of the common mistakes is that the jockey pump is not adjusted properly and causes the main pump to turn on repeatedly; In the long run, this raises depreciation and increases the probability of damage during fire. Another mistake is closing valves after repairs and forgetting to open them, which can be prevented by installing status indicators and operating procedures. Having a regular service schedule, especially in Tehran, where many engine houses are faced with dust, humidity or limited ventilation, is necessary to increase the life and reliability of the fire booster pump.
