Classification of centrifugal pumps:
1. Classification according to the number of working impellers
1. Single stage pump: that is, there is only one impeller on the pump shaft.
2. Multistage pump: that is, there are two or more impellers on the pump shaft. At this time, the total head of the pump is the sum of the heads generated by N impellers.
2. Classification by working pressure
1. Low pressure pump valve: the pressure is less than 100m water column;
2. Medium pressure pump: the pressure is between 100-650m water column;
3. High pressure pump: the pressure is higher than 650m water column.
3. Classification according to the way of impeller water inflow
1. Single side water inlet pump: also called single suction pump, that is, there is only one water inlet on the impeller;
2. Double side water inlet pump: also called double suction pump, that is, there is a water inlet on both sides of the impeller. Its flow rate is twice that of single suction pump, which can be approximately regarded as two single suction pump impellers put together back to back.
4. Classification according to the joint form of pump shell
1. Horizontal split pump: that is to say, there is a joint on the horizontal plane passing through the axis line.
2. Vertical joint surface pump: that is, the joint surface is perpendicular to the axis line.
5. Classification by pump shaft position
1. Horizontal pump: the pump shaft is in the horizontal position.
2. Vertical pump: the pump shaft is in the vertical position.
6. Classification according to the way that the water from the impeller leads to the press out chamber
1. Volute pump: after the water comes out of the impeller, it directly enters the pump shell with spiral shape.
2. Guide vane pump: after water comes out of the impeller, it enters the guide vane set outside it, and then enters the next stage or into the outlet pipe
