Booster pump is a special name for many pumps, which is installed on the pipeline to boost the pressure. Generally speaking, the pipeline booster pump refers to the pump installed on the pipeline to deliver liquid, and is not limited to a certain type or form of pump. It can be vertical or horizontal, such as vertical multi-stage centrifugal pump, horizontal multi-stage centrifugal pump, vertical single-stage centrifugal pump, horizontal single-stage centrifugal pump, self-priming centrifugal pump and so on. Generally speaking, the pipeline booster pump in the industry generally refers to the pump with pipeline structure, which can be directly installed in series like a pipeline.

Since the booster pump belongs to the nickname of pump, its selection also follows the selection of centrifugal pump, and the parameters to be noted include flow, head, material, medium specific gravity, etc. The pump flow and head we usually refer to are their rated flow and rated head. The so-called rated flow and rated head refer to the pumping capacity and the height to which the pump can pump water when the pump inlet and outlet are fully open and working at power frequency (50Hz). The rated head corresponding to the rated flow of the pump is called the best working point of the pump. This working point is the working point with the highest pump efficiency. Therefore, the pump with the best working point parameters shall be selected as far as possible when selecting the pump, which can not only give play to the best potential of the pump, but also improve the service life of the pump.
