The Difference Between Booster Pump And Circulation Pump

1. Working principle
Circulating pump: In terms of the function of the pump, circulation refers to the structure of the pump, and the two are completely different concepts. The working principle of a circulating pump is to circulate water. The pump used to circulate water is called a circulating pump, for example, the hot water in a water heating pipeline is circulated by a circulating pump.
Booster pump: first fill the booster pump with liquid, and then start the centrifugal pump. The impeller rotates rapidly. The blade of the impeller drives the liquid to rotate. When the liquid rotates, it flows to the outer edge of the impeller by inertia. At the same time, the impeller absorbs liquid from the suction chamber. This force works on the liquid (official account number: pump manager), so that the liquid gets energy and flows out of the impeller. At this time, the kinetic energy and pressure energy of the liquid increase.

2. Installation location
Booster pumps are generally installed on the inlet pipeline. After cutting a section of the original pipeline, the pump can be connected in series to the pipeline; The circulating pump needs to be installed on the return water pipe to increase the pressure of the system and assist in circulation. Cut a section of the pipeline with scissors and connect the pump in series to the pipeline.

3. Applicable scope
Booster pumps are generally used in centralized heating systems, where the small drop in solar energy leads to low water pressure, and when the water pressure in the water heater is low and requires boosting; The circulating pump is mainly designed for self heating users, or for the circulation of heating systems and underfloor heating hot water in large and medium-sized households. If the inlet water temperature is acceptable and the outlet water temperature is low, installing a circulating pump can solve the problem. However, if the inlet and outlet water temperatures are both low, it is necessary to first investigate the cause of the overheating.

4. Boosting strength
Booster pumps mainly solve the problem of low water pressure and belong to the type of pumps with low pressure. This is mainly determined by the structure of the water pump, and the booster pump relies on centrifugal force to increase pressure; Compared to booster pumps, circulation pumps have a higher pressure and can drive the circulation of the entire heating system.

5. Product operation
Booster pumps are mostly automatically controlled, with the switch being an automatic water flow switch control. As long as there is water flow, the switch will start automatically, and if there is no water flow, it will shut down automatically; Most circulating pumps are manually controlled and require manual operation of the switch to enable and stop the water pump.
Due to the many differences between booster pumps and circulation pumps mentioned above, users must pay attention to distinguishing and distinguishing between them during procurement and use, so that both pumps are fully utilized and suitable for their needs. Otherwise, it will be difficult to meet their own needs and even damage the overall system. When you are unsure which type of water pump to choose, try to consult professionals and listen to their purchasing suggestions.
