1. Operation simple horizontal pump, because the impeller is above the water, before the pump starts, to use a vacuum pump to pump water, because the vertical pump impeller, generally submerged in water, can be directly launched.
2. Installation area contains the driver, including the vertical pump, only half of the space on the pump to meet the. Especially in the large pump today, this advantage is more outstanding.
3. Is conducive to prevent cavitation vertical pump impeller generally submerged in water, you can use the NPSH can take a large number of. Thus, the pump running at a greater than the planning point of the flow will not attack cavitation.
But because it is a vertical, longitudinal longer pump, disassembling and assembling crane hoisting height is higher, above the pump to have space to meet, this is the disadvantage of the vertical pump. However, the vertical pump is simply installed outdoors, so it will not become a question.
