Multistage horizontal pumps
Multistage sectional centrifugal pumps are more advanced. The design of such pumps provides for several impellers and stages, which are arranged in series one after another. In such of construction, the water flow moves from the intake hole of the stage to the inlet of the next stage, while the final pressure indicator is equal to the sum of the pressures that each stage of the pump creates. In these type of pumps, the common shaft can be oriented both vertically and horizontally. When choosing a centrifugal pump, you should pay attention to the fact that pumps with a mechanical shaft seal are more modern than outdated analogs with stuffing box packing. The main advantage of the first configuration is that it maintains tightness and no leakage, as well as a good level of tightness against vibrations and small shaft movement.
