The difference between single - stage deep well pump and multistage deep well pump

The difference between single - stage deep well pump and multistage deep well pump
1, single-stage deep-well pump is only one impeller deep-well pump, the maximum lift is only 125 meters;
2, multistage deep well pump is a pump with two or more impeller, the maximum lift can be more than 125 meters; multi-stage pump in the single stage pump head need to be equipped with two motor cases, you can increase the number of impellers To match the four motor, which can improve pump life and reduce the unit noise, but the multi-stage pump repair is relatively single-stage pump is difficult.
3, the actual needs of the pump head less than 125 meters, according to the pump area, pump prices (multi-stage pump is generally higher than the single-stage pump prices), and other factors considered the choice of single-stage pump or multi-stage pump.
With the advancement of technology, single-stage impeller pump can increase the pump speed to improve the pump head, can replace the multi-stage pump, but the price is a little expensive
