What are the advantages of vertical mixed flow pump?

Mixed flow pump, commonly used in farmland irrigation and drainage, industrial and urban water supply and drainage and other occasions. According to the different types, mixed flow pump is divided into horizontal mixed flow pump and vertical mixed flow pump. Although both are mixed flow pumps, but both have obvious differences and differences. So, for the horizontal mixed flow pump, vertical mixed flow pump which advantages and advantages?
     From the author years of experience in the pump, vertical mixed flow pump has the following major advantages:
     1, simple operation
     Horizontal mixed flow pump, because the impeller is above the water, before the pump starts, use a vacuum pump to the pump water. While the vertical mixed-flow pump, because its impeller usually sink in the water, can be started directly.
     2, the installation area is small
     Compared to the horizontal mixed flow pump, vertical mixed flow pump installation area only need horizontal mixed flow pump is generally enough. Greatly saves the floor space.
     3, more anti-cavitation
     Vertical impeller pump impeller is usually sinking in the water, can take advantage of the NPSH can take a larger number. For this reason, cavitation is less likely to occur.
