1. What is a booster pump
A booster pump is a water pump used to boost pressure, which generally refers to the ability to supply liquid in the pipeline. The general term for pumps with extra pressure, which are mainly used for water heater pressurization, low water pressure in high buildings, sauna, bathing and other pressurization, pressurization with insufficient water pressure on the top floor of the apartment, solar automatic pressurization, reverse osmosis water purifiers For supercharging, etc. The booster pump does not refer to a certain type of pump, as long as the pump has a booster function, so the booster pump contains a wide range of pump products, which can be pipeline pumps, centrifugal pumps, sewage pumps, self-priming pumps, multi-stage pumps Pumps and other types of pumps.
The booster pump is very popular in many households, especially some users on high floors almost have to use the booster pump. The conventional booster pumps are divided into: domestic booster pumps installed in individual households and pipeline booster pumps used for water supply by water companies or second water supply installations in communities, and can also be used as boosters for the second booster use of factory water. pressure pump. The meaning of the booster pump is to perform a second booster on the basis of the water pressure in the original pipeline. The pressure at the pump inlet plus the pressure provided by the booster pump is the entire pump outlet pressure. The booster pump can be divided into vertical installation or horizontal installation. The most commonly used household booster pump is: WG type small household booster pump, and the most commonly used second water supply booster pump is: ISG pipeline booster pump, ISW Horizontal pipeline centrifugal pump or the new DL vertical stainless steel light multistage pump. If you want to make the non-self-priming booster pump achieve the self-priming effect (the pump is located above the pool), you can install a bottom valve at the suction port of the pump.
Second, what is a self-priming pump
The self-priming pump is a self-priming centrifugal pump, that is, the pump is installed at a place higher than the liquid level, The first time the pump is filled with water, the self-priming pump is started and the water can be pumped up and drained. The suction depends on whether the impeller is immersed in water after shutdown. The self-priming pump can ensure that the impeller can be immersed in water after each shutdown because of its unique pump cavity structure. Self-priming pump not only has the function of self-priming pump but also has the function of booster pump, so we can also call self-priming pump as self-priming booster pump. It has the advantages of compact structure, convenient operation, stable operation, easy maintenance, high efficiency, long life, and strong self-priming ability. There is no need to install a bottom valve in the pipeline, and it is only necessary to ensure that there is a quantitative liquid in the pump body before work. Different liquids can be self-priming pumps with different materials.
Third, what is the difference between a self-priming pump and a booster pump
1. From the installation position
The booster pump is generally installed on the water inlet pipeline. After cutting a section of the original pipeline, the pump can be connected to the pipeline in series. The water level in the middle of the pipeline is higher than the pump body; the self-priming pump needs to be installed on the return pipe to increase the Press the system pressure to help its circulation, cut a section of the pipeline with scissors, and connect the pump to the pipeline in series, and the water level in the middle of the pipeline is lower than the pump body.
2. From the scope of application
The booster pump is generally used in the central heating system, and the water pressure is small due to the small drop of solar energy, and the water heater When the water pressure is small and pressurization is required; the self-priming pump is mainly used for self-heating users, or the circulation of heating systems for medium and large households, and the circulation of floor heating and hot water. If the inlet water temperature is OK and the outlet water temperature is low, installing a self-priming pump can solve the problem, but if the inlet and return water temperatures are both low, you need to find the reason for the lack of heat first.
3. From the perspective of booster strength
The booster pump mainly solves the problem of low water pressure, and belongs to the type of pump with low pressure. This is mainly determined by the structure of the water pump. The booster pump relies on centrifugal force to boost pressure; while the self-priming pump has a higher pressure than the booster pump, which can drive the circulation of the entire heating system.
4. From the perspective of product operation
The booster pump is mostly automatic control, that is, the switch is the automatic switch control of water flow, as long as there is water flow switch automatically Start, no water flow will automatically close; most of the self-priming pumps are manually controlled, and the switch needs to be manually turned on to realize the pump running and stopping.
Fourth, which effect is better between self-priming pump and booster pump
Both self-priming pump and booster pump can pressurize tap water and boost pressure The pump is equipped with a constant pressure device, which can keep the water pressure in the water pipe at a relatively average pressure. However, the self-priming pump does not have a constant pressure device. When it is installed on a pipeline that already has water pressure, the water meter glass will be sucked and broken in severe cases.
If the water is not interrupted, you can use a booster pump. If the water is often interrupted, you must prepare a container (pool, water tank, etc.). The container can be equipped with a drain pipe or a booster pump. Only the self-priming pump can be installed when the drain pipe is installed.
Suitable for booster pump:
Households using tap water: Because tap water is under pressure, especially for households living in high floors, it is necessary to With the help of a booster pump to boost, let the pressure reach about 0.65MPa, in order to achieve normal use.
Suitable for suction pumps:
Like many rural homes, there is no running water, so you can only use well water, wells or water tanks The position of the water purifier is relatively low, so if the self-priming pump is used, the water can be automatically sucked into the water purifier.
In addition, when purchasing self-priming pumps and booster pumps, pay attention to the following items:
When purchasing booster pumps, provide the manufacturer with the model of their own water supply pipes , caliber, and the flow size and head required by themselves, so that the manufacturer can provide a suitable pump according to the user’s requirements.
When buying a self-priming pump, it is basically the same as buying a booster pump. Of course, the user can also explain to the manufacturer what liquid medium he wants to pump, so that the manufacturer can match the user. The self-priming pump, whether it is pumping clean water or other media.
