A centrifugal pump is a machine that continuously transports liquid and increases the pressure of the liquid. At the same time, it has the characteristics of corrosion resistance, small footprint, convenient maintenance and high cost performance. Therefore, there are strong regulations in the market. There are two types of single-stage centrifugal pumps and multi-stage centrifugal pumps on the market. How to choose single-stage centrifugal pump and multi-stage centrifugal pump? Generally speaking, a single-stage centrifugal pump is a pump with only one impeller, so it is called a single-pole. Multi-stage centrifugal pump refers to a pump with two or more impellers, that is, multiple single-stage centrifugal pumps are connected in series, of which two impellers are two centrifugal pumps, three impellers are three-stage centrifugal pumps, and multiple impellers are Multiple centrifugal pumps to increase pressure. The lift of a single-stage centrifugal pump is 125 meters, while the lift of a multi-stage centrifugal pump will exceed 125 meters due to the increase in pressure. In other words, single-stage centrifugal pumps have low pressure and large flow, while multi-stage centrifugal pumps have high pressure and small flow. Single-stage centrifugal pumps are smaller, smaller in area, and simpler to maintain than multi-stage centrifugal pumps, which are larger and more expensive than single-stage centrifugal pumps, and more complicated to maintain than single-stage centrifugal pumps. Whether it is unipolar or multi-level, what suits you is more important. When you choose, it is more cost-effective to choose according to your own needs. When a centrifugal pump is used, regular maintenance should be performed. During use, some dust may fall on it, and there may be some residue in the liquid left inside the centrifugal pump. At this point, we should scrub and clean it for easy access later. This is also a way to increase the service life of centrifugal pumps.
