Brief description of multi-stage pump and single-stage pump difference

[Asia Pump Network News] Multistage pumps and single-stage pumps are centrifugal pumps, the difference between the two is not large. The main difference is mainly the number of impellers and head of the pump, as follows: Multi-stage pump and single-stage pump difference Single-stage pump is only one impeller pump, the maximum lift is only 125 meters. Multi-stage centrifugal pump is more than two impeller, multi-stage multi-stage water and pressure water, which will raise the water to a high position, the maximum lift can be more than 125 meters. Multi-stage pump and single-stage pump in the design, use and maintenance of multi-stage pump has a higher technical requirements, coupled with high efficiency multi-stage centrifugal pump to meet the needs of high-lift, high-flow conditions, petrochemical , Chemical, power, construction, fire and other industries have been widely used, so the price will be more expensive than single-stage pump. In summary, the biggest difference between the two is the number of different impeller, but as technology advances, single-stage impeller pump can also improve the pump lift by raising the pump speed, so the two in the work efficiency will be towards With the continuous improvement of the direction of development.
