Advantages and disadvantages of vertical pipeline centrifugal pump

advantage:
1. Small size and small floor space.
2. Simple structure, few parts and easy maintenance.
3. The flow and pressure are stable, and the vibration is small when the pump operates normally.
Disadvantages:
1. The efficiency of the pump is low when it is operated at a small flow below the rated flow.
2. It is suitable for conveying various liquids with low viscosity. The viscosity of the liquid has a great impact on the performance of the pump.
3. Poor self suction capacity and easy evacuation. If the dynamic liquid level of the pumped liquid is below the center line of the pump, it must be filled or evacuated before starting the pump, otherwise the centrifugal pump cannot work normally.
Although the vertical pipeline centrifugal pump can now meet the basic use requirements, we should also see its shortcomings. We also need to increase research and development efforts to ensure that it can be more efficient, safe and fast in the transportation process.
