What is a booster pump? Use in what case?

Among the types of domestic water pumps on the market, booster pumps are quite common. So what is a booster pump? How does it work and how does it work? When should a booster pump be used? Tnhelearning.edu.vn will help you answer in the article below.

What is a booster pump?

Booster pump (pressure pump) is a type of pump used for the purpose of increasing the pressure of water circulating in the pipeline, making the water flowing out of the nozzles stronger and more usable. Often used to increase the water pressure in the washing machine, limiting the shortage of water, affecting the life of the machine.

The most commonly used booster pump is an automatic pump. When the user opens any faucet to get water to use, the pump will automatically turn on and create pressure to push the water flow stronger to meet the user’s wishes. And when the user closes the faucet, the pump automatically turns off.

Structure and working principle of booster pump

Structure: The booster pump consists of two main parts, the pump body and the pressure tank . In addition, this unit also has other accessories such as pressure switch, suction inlet, outlet, base and power cord.

Working principle of booster pump:

The booster water pump works on the pressure change in the water pipe. When the pressure in the pipe changes, the pressure in different positions on the pipe will be different.

• When the pressure drops low (when you open the drain valve), the sensor system inside the pipe will transmit a signal to the pressure switch unit and make the pump work.
• When the pressure increases to high and the pressure decreases (when you close the drain valve), the switch will automatically disconnect the power to stop the pump from working.

Advantages and disadvantages of booster water pumps

a. Advantages of booster pump:

• The pressure in the water supply system can be increased or kept stable to meet the intended use.
• Relatively compact size.
• Low noise level.
• Good corrosion resistance.
• Can be installed directly with the pipeline.
• Disassembly and repair are relatively easy.
• Can work in a variety of environmental conditions.

b. Disadvantages of booster pumps:

Booster pumps have some disadvantages but do not affect the usability much such as: High cost, large pump capacity, so it will consume more power, less types and models than other pumps, only used under certain conditions.

When should a booster pump be used?

Booster water pumps are used when the water pressure is weak and cannot meet the daily needs of the family, especially such as laundries, hotels and restaurants that need to use water in large quantities.

Booster pumps are also used to increase the working efficiency of machines such as washing machines , solar water heaters, water heaters,…

Some families cannot afford to install a tank on the roof, so they will draw water directly from the underground tank or pipe. In this case, a booster pump must be used, and a mechanical booster pump must be selected (using a pressure relay).

Types of booster pumps available today

1. Built-in booster pump

This is a common high-pressure pump, with a system of pressure vessels and pressure relays installed. This type of pump is often used to pump large systems with many nozzles or as a booster pump for the entire building.

2. Mechanical booster pump

The mechanical booster pump is a pump line that is manufactured by the manufacturer with a relay and a pressure tank. Thanks to its convenience and ability to work well in all household conditions, this type of booster pump is the most popular and widely used today.

3. Electronic booster pump

Electronic booster pump is controlled by electronic circuit board, all operations and control modes are fully automatic. Electronic booster pump quiet operation, high precision, the whole pump is compactly designed.

The disadvantage of electronic booster pumps is that the pump only works when there is a push of the original water flow through. Therefore, if there is no initial flow or the initial flow is too weak, the pump will not start automatically.

4. Booster pump with inverter system

Booster pumps use current frequency converter technology to turn on/off and automatically adjust the number of revolutions of the pump shaft to meet water usage needs.

The disadvantage of the inverter series of booster water pumps is that the cost is quite high, so these pumps are mainly used in high-class apartments or in large water pumping systems that need high stability.
