What is the difference between a single-stage pump and a multi-stage centrifugal pump?

The differences between single-stage pumps and light multi-stage centrifugal pumps are as follows:

1. A single stage pump refers to a pump with a maximum head that can only reach 125 meters and has only one impeller.

2. Light multi-stage centrifugal pump refers to a pump with a maximum lift of up to 125 meters and two or more impellers.

3. Multi-stage centrifugal pump In the case that the single-stage pump head needs to be equipped with a two-stage motor, the four-stage motor can be used by increasing the number of impellers, which not only improves the service life of the pump but also effectively reduces the unit's life. Noise, but the maintenance of multi-stage centrifugal pumps is more difficult than single-stage pumps.

4. If the actual lift required by the pump is less than 125 meters, it can be comprehensively considered according to the area of the pump room and the price of the pump (the price of the multi-stage centrifugal pump is usually higher than the price of the single-stage pump). Whether to choose a light multi-stage centrifugal pump or a single-stage pump.

With the continuous development of technology and advances in technology, the pump of the single-stage impeller has been able to increase the lift of the pump by increasing the speed of the pump. Therefore, the single-stage pump can replace the multi-stage pump now, of course, the price is also more expensive.
