Classification of centrifugal pumps:
There are many types of centrifugal pumps, and the following methods are common in classification methods.
1. According to the impeller suction method: single-suction centrifugal pump double suction centrifugal pump;
2, according to the number of impellers: single-stage centrifugal pump multi-stage centrifugal pump;
3. According to the impeller structure: open impeller centrifugal pump semi-open impeller centrifugal pump closed impeller centrifugal pump;
4, according to the working pressure: low-pressure centrifugal pump medium pressure centrifugal pump high-pressure centrifugal pump;
5, according to the position of the pump shaft: horizontal centrifugal pump side vertical centrifugal pump.
