What is a firefighting booser pump?

Fire pump booster system

The booster pump system is a booster pump that acts as an intermediary between the water source and endpoints such as valves, sprinklers, etc. This system takes water from the source and pressurizes it to achieve the desired pressure at the endpoints. Booster means “amplifier” in a general sense. In fact, by using a booster in fire pumps, high water pressure is provided for the fire extinguishing system or network. The booster pump consists of one or more electropumps that are connected in parallel. They are individually controlled by a smart control panel. This system is built with the aim of keeping the pressure of water consumption uniform and constant at a certain flow rate and without restrictions on the amount of water consumption. In this way, the pressure fluctuation resulting from the consumption change in the system is controlled and eliminated. This work is done by controlling the speed of the electric motors and also the order of entry of each pump into the water supply circuit. In general, the fire pump booster is a part of the fire fighting system to fight and suppress the fire. This pump increases the pressure of the fluid, which, depending on its structure, may be liquid or even gas. A gas booster pump is very similar to a gas compressor and is used to increase the pressure of available gas/water. These pumps are not the only equipment used to move water in a system. They work with a source pump to increase fluid pressure. Booster pumps are required in a wide range of applications, including industrial and construction projects, etc. For example, these pumps are able to create opposite pressure to move water, even in difficult conditions. Sprinkler systems may also need to be boosted because they require high pressure water to function properly.

Some of the major industrial applications of these pumps are:

Filtration

reverse osmosis

Air conditioning

Boiler feed

Any industrial process that requires high fluid pressure.

How does a fire pump booster work?

These pumps work like any other normal pump. Most of these booster pumps are centrifugal pumps that take water from a source, move it through a single-stage or multi-stage impeller to increase water pressure. The high-pressure water then flows through an outlet. You can also install a series of booster pumps along a pipeline to reach the required pressure.

What is the difference between a variable speed pump and a fixed speed pump? Generally, a constant speed pump motor operates at its own speed regardless of flow conditions. In a variable speed pump, the pressure produced by the pump is determined by the amount of water required by the application.

Variable speed booster pumps have several advantages over fixed speed pumps, which include:

1. Elimination of energy losses of pressure reducing valves
2. Extending the life of the engine without being constantly on
3. Reducing the operating cost during the life cycle of the pump
4. Increasing the life of motor bearing and pump sealing
5. Minimizing water suction in the system
