With the increasing expansion of vertical constructions, high-rise towers and residential, commercial and office complexes in the metropolis of Tehran, the issue of safety and fire protection has become one of the most vital concerns of employers, engineers and owners. One of the main pillars in water fire extinguishing systems is to provide proper pressure and flow of water in all floors of the building. This vital task is the responsibility of the fire pump booster. The design and implementation of the fire booster pump system in Tehran requires deep technical knowledge, compliance with international standards, and high executive experience due to the special geographical features, high urban density, as well as the legal strictures of the fire department and safety services of Tehran Municipality. In this article, we will comprehensively review the principles of design, legal requirements, implementation points and the vital role of specialist companies such as Smart Smart in this field.

What is a fire pump booster and why do we need it?

Under normal conditions, the pressure of the city water network is not enough to supply the water needed by the fire extinguishing systems, especially in the upper floors of high-rise buildings in Tehran. A fire pump booster is a set of two or more water pumps that are connected in parallel to provide the necessary flow and pressure for equipment such as fire extinguishers and sprinkler systems at the time of an accident.

The main goal of designing and implementing the fire booster pump system in Tehran is to keep the water pressure constant throughout the fire extinguishing network of the building; So that even with the simultaneous opening of several nozzles or sprinklers, there is no pressure drop in the system and fire extinguishing is done with maximum efficiency. With a detailed understanding of this technical need, Smart Smart Company designs and implements systems that enter the circuit with the highest reliability in emergency situations.

Tehran fire department regulations for pump booster design

Tehran Municipality's firefighting and safety services organization has established very strict guidelines and criteria for approving the fire extinguishing systems of buildings. Any defect in the design and implementation of the fire booster pump system in Tehran can lead to the non-issuance of the construction project and endangering the lives and property of the residents. Some of the most important criteria of this organization are:

The necessity of using approved pumps (with valid national or international certificates such as UL/FM or standards approved by the Tehran Fire Department).

The existence of at least one reserve pump (Standby) with the same characteristics as the main pump (Duty) to ensure the operation of the system in case of failure of the first pump.

Using a forward pump or a jockey pump to compensate for minor pressure drops caused by possible leaks in the piping and prevent the main pumps from turning on frequently.

The support of the booster pump electrical panel from the building's emergency power system (diesel generator) so that the fire extinguishing system can continue to work without interruption in case of a power outage during a fire.

As one of the pioneers of this industry, Top Smart Group carries out all the stages of design, calculations and approval of this equipment in accordance with the latest edition of the National Building Regulations (the third topic) and the Tehran Fire Organization regulations.

Stages of design and implementation of fire booster pump system in Tehran

The process of designing and implementing the fire booster pump system in Tehran is a completely engineering work and includes the following detailed calculation and execution steps:

Choosing the right pump: based on the performance curve of the pumps (Pump Curves), pumps are selected whose working point is in the best efficiency area. Also, according to the NFPA 20 standard, fire pumps must be able to provide at least 65% of the nominal pressure at a flow rate equal to 150% of the nominal flow rate.

Command and control board design: The booster pump control board is the mastermind of the system. The switchboard should be designed to automatically turn on the pumps when the mains pressure drops, but the shutdown of the main fire pumps should usually be done manually to avoid sudden interruption of water flow during firefighting.

Execution of collectors and engine room piping: In the implementation phase, the construction of suction and heat collectors is done with Manisman pipes (seamless) and with appropriate thickness. Installation of shock absorbers, one-way valves, gate valves and relief valve (pressure relief valve) is one of the key requirements of this department.

Using experienced accounting engineers and expert executive teams, Hoshmand Topr guarantees that all these steps are carried out with millimeter accuracy and using the best materials available in the market.

The main components of the booster fire pump

A standard booster pump system that is designed for firefighting consists of various parts and equipment, the coordination between which ensures the flawless operation of the system. These components are:

The main electropumps: usually there are two floor or vertical centrifugal pumps that are responsible for providing the main flow rate and pressure.

Jocky pump: It is a small pump that is installed to compensate for minor pressure fluctuations in the piping network to prevent the depreciation of the main pumps.

Aligned metal chassis: All pumps and electric motors are installed on a strong and aligned metal chassis to prevent vibration and damage to the pump shaft.

Input and output collectors: they are diameter pipes that direct the input water to the pumps and collect the output water under pressure and send it to the fire extinguishing network of the building.

Control equipment and instrumentation: includes pressure switches (push switches), manometers (pressure gauges) and flow sensors that send the necessary commands to the electrical panel.

Pressurized source (diaphragm): It is used to depreciate the ram impact in the network and reduce the number of times the jockey pump turns on and off.

The top smart engineering team always uses reliable brands and high-quality parts in the design and implementation of fire booster pump system projects in Tehran so that the lifespan and stability of the system is at the highest possible level.

Key points in the installation and operation of fire extinguishing systems in Tehran projects

The physical implementation of the booster pump in the engine house of Tehran buildings requires attention to many technical details. One of the most important points is the correct positioning of the booster pump in the engine room. Easy access for maintenance and repair, proper ventilation of the engine room to cool the electric motors and diesel generator, as well as sound and vibration insulation to prevent the transmission of the sound of the pumps to residential units are of great importance.

Another point is the supply of water for fire fighting. The fire water storage tank must have a sufficient volume to supply water to the system for the period of time specified in the regulations (usually at least 30 to 60 minutes of continuous operation of the system). The suction pipe of the booster pump must always be fed by gravity (feeding from above) from the water tank so that the pumps do not suffer from cavitation (bubble formation and corrosion of the vanes). Houshman Topr designs and executes the most optimal piping routes and equipment placement by carefully examining the architectural plan and building facilities.

Service, maintenance and periodic testing of booster fire pumps

Even if a fire extinguishing system is designed and implemented with the best quality, without regular periodic maintenance and tests, it may not be effective on the day of the accident. Clogging of the pump blades, jamming of the shafts due to long-term non-use, air discharge of the diaphragm source and pressure failure of the switches are among the problems that occur in the absence of regular service.

Based on international standards such as NFPA 25, the fire pump booster system should be tested weekly, monthly and annually. Testing the automatic start of pumps by simulating pressure drop, checking the amperage consumption of electric motors, testing the performance of safety valves and checking the water level of storage tanks are among the things that should be recorded in the maintenance checklist. By providing technical support services and periodic maintenance contracts, Smart Smart Company gives the assurance to building managers that their fire extinguishing system is always on full alert.
