What are the advantages and disadvantages of multistage centrifugal pumps?

Multi-stage centrifugal pump can change the pump material, sealed form of oil, hot water, corrosive media transport. Research into the advantages and disadvantages of multistage centrifugal pumps has always been the job of researchers and pump professionals. What are the advantages and disadvantages of multistage centrifugal pumps? Multistage centrifugal pump advantages and disadvantages Which multistage centrifugal pump advantages: 1, multistage centrifugal pump for the vertical structure, with a small footprint characteristics, pump center of gravity coincident with the pump foot, and thus stable operation, small vibration, life long. 2, multi-level centrifugal pump diameter and the same horizontal centerline, without changing the pipeline structure, can be directly installed in any part of the pipeline, the installation is extremely convenient. 3, the motor plus rain cover can be placed directly in the outdoor use, without the need to build pump room, greatly saving capital investment. 4, multi-stage centrifugal pump head can be changed by pump series (number of impeller) to meet different requirements, it is applicable to a wide range. 5, the shaft seal with carbide mechanical seal, reliable seal, no leakage, mechanical loss. Multi-stage centrifugal pump Disadvantages: 1, for the delivery of solid particles content of not more than 1.5% of neutral mineral water and similar other sewage, medium temperature is not higher than 80 ℃. 2, the pressure does not exceed 0.6MPa. 3, for delivery temperature of -20 ℃ ~ 105 ℃, non-solid particles, corrosive liquids. Understand a product, its characteristics must be a very good way to understand. China's pump after years of market panning, has developed very mature, multi-stage centrifugal pump as one of the typical equipment, has been well received. I believe in the future of multi-stage centrifugal pump strengths and weaknesses of the research work will continue, not only for the multi-stage centrifugal pump in order to develop, but also for the development of various industries.
