Multi stage pump refers to a pump with two or more impellers, which can absorb and press water in stages and stages, so as to lift the water to a very high position. The lift can increase or decrease the number of stages of pump impellers according to needs; When the single-stage pump head needs to be equipped with two-stage motors, the multi-stage pump can be equipped with four-stage motors by increasing the number of impellers, which can improve the service life of the pump and reduce the noise of the unit. When the actual required lift of the pump is less than 125 meters, the selection of a single-stage pump or a multi-stage pump can be comprehensively considered according to the area of the pump room, the pump price (the price of a multi-stage pump is generally higher than that of a single-stage pump) and other factors.
