Structural Form And Features Of Centrifugal Pump

Centrifugal pumps can be divided into vertical pumps and horizontal pumps according to their structural forms.
Vertical pumps are characterized by small floor space and easy installation. The disadvantage is that the center of gravity is high and it cannot be used where there is no fixed seat cushion.
Horizontal pumps are characterized by low center of gravity, wide range of applications, and good stability. The disadvantage is that compared with the vertical pump, it occupies a larger area, is larger in size, and is heavier in weight.
Centrifugal pumps can be classified as follows according to the requirements of head flow and the series of impeller structures:
1. Single-stage single-suction pump: The pump has only one impeller and one suction port on the impeller. The flow range is: 4~300m2/H. The lift ranges from 1 to 150 meters.
2. Single-stage double-suction pump: The pump has one impeller and two impellers. The flow range is 100~30000m2/H. The lift ranges from 5 to 120 meters.
3. Single-stage multi-suction pump: The pump has multiple impellers. The discharge chamber of the first impeller is connected to the suction port of the second impeller, and so on.
