A centrifugal pump is a common industrial device used to transport liquids. In centrifugal pumps, multistage and single-stage centrifugal pumps are two common types. There are some differences in their structure and working principle, which will also have an impact on their efficiency. In contrast, the multistage centrifugal pump is a centrifugal pump composed of a number of impellers, the liquid through the impeller and the role of stage pressure, the pressure increases and flows to the outlet. Single-stage centrifugal pump is simple, compact structure, suitable for low pressure, small flow conditions, because there is only one impeller, the pressure of single-stage centrifugal pump is relatively low. Therefore。
In fact, only a small number of parameters of the multi-stage centrifugal pump and the single-stage centrifugal pump overlap, that is, when the head is below 150 meters, it is possible to choose either a multi-stage centrifugal or a single-stage centrifugal pump, in this premise, generally speaking, the efficiency of the single-stage centrifugal pump is higher. However, when the head is more than 150 meters, the single-stage centrifugal pump is not possible, so there is no need to compare.
