The main difference between self-priming pump and booster pump is that the self-priming pump has self-priming ability, while the booster pump does not have self-priming capacity. The self-priming pump installed on the pool can suck the low-level liquid into the self-priming pump body, and then transport to other places. If the liquid level is higher than the self-priming pump, the self-priming pump can not be used, and the booster pump can meet the requirements. If the liquid level is higher than the pump, select the self-priming pump Suction pump will lead to the phenomenon of motor over current at the moment of starting the self-priming pump, or the phenomenon of mechanical seal leakage occurs, so do not choose the self-priming pump if the liquid is higher than the pump or the inlet of the self-priming pump has pressure.
The booster pump is mainly installed on the pipeline, which is used for the place where the pressure of the pipe network is low and the water can not be delivered to the user by its own pressure, or some equipment needs higher pressure, so a booster pump is specially added to boost the pressure. The booster pump does not have the self-priming function, and the liquid must flow into the pump body, so that the booster pump can work Booster pump or all centrifugal pump series are booster pump products. If you want to use a booster pump when the liquid is lower than the pump, you can choose to install a bottom valve at the bottom of the suction port to fill the booster pump and the inlet pipe with water, and the water can be pumped up. However, this effect is not ideal. After the pump is stopped for a long time, the liquid in the inlet pipe will return to the pool and the next start-up needs to be filled with water. The operation is more complicated, so the liquid is lower than the pump, so we still need to build It is suggested that the effect of self-priming pump is better.
