Centrifugal pump classification, it is based on the different structural characteristics of the division. First, according to the number of working impeller to classify 1, single-stage pump: that is, only one impeller in the shaft. 2, multi-stage pump: that is, there are two or more impellers on the pump shaft, then the total pump head is the sum of the lift produced by n impellers. Second, according to the classification of working pressure 1, low-pressure pump: pressure less than 100 meters of water column; 2, medium-pressure pump: pressure in the range of 100-650 meters of water; 3, high pressure pump: pressure higher than 650 meters of water column. Third, according to the classification of the impeller water way 1, one side of the water pump: also known as single suction pump, that is, only one inlet on the impeller; 2, bilateral water pump: also known as double suction pump, Side of a water inlet. Its flow rate is double that of a single suction pump, which can be approximated as two single-suction pump impellers placed back-to-back together. Fourth, according to the pump shell combined with the type of seam 1, the level of open pump: that is, through the axis of the horizontal plane with a joint seam. 2, the vertical joint pump: that is, the junction plane and the axis of the vertical. Fifth, according to the pump shaft position to classify 1, horizontal pump: pump shaft is located in horizontal position. 2, vertical pump: pump shaft is located in the vertical position. Six, according to the impeller out of the way to the pressure chamber out of the classification 1, volute pump: water from the impeller, directly into the pump shell with a spiral shape. 2, guide vane pump: water from the impeller out into the guide vane set outside it, and then into the next level or into the outlet pipe. Usually we say that a pump is a multistage pump, which means how much the impeller. According to other structural features, it may be horizontal pump, vertical joint surface pumps, vane pumps, high pressure pumps, single-inlet pumps and so on. So according to different, the name is not the same. In addition, according to the use can also be classified, such as pumps, pumps, condensate pumps, ash pumps, circulating pumps and so on.
