离心泵由于结构简单、效率高、流量大、无脉动、价格低而广泛使用，离心泵约占全部工、农业用泵量的百分之八十以上。共同的特点：结构简单液流平稳无脉动中小流量领域有相似的效率和运行曲线。挠性泵的优势：离心泵只能用于稀薄、低粘度的液体，无法输送中、高粘度的流体、半流体。而挠性泵从低到高粘度均可。离心泵无法输送含较大悬浮颗粒的介质。离心泵无法输送含气液、泡沫液。离心泵转速高，不能低转速运行，所以对介质剪切极大，不适合输送对剪切具有敏感的介质。离心泵无自吸能力。如要自吸需加附加装置，如储液罐、底阀，次启动需灌液，完成自吸动作的速度慢；应用于卫生领域，储液罐有可能成为新的污染源。此外，离心泵的安装位置受限。后，请注意，离心泵不能作为计量泵使用。一般来讲，挠性泵与离心泵之间无竞争关系。挠性泵作为离心泵的替代泵种，主要用于吸排离心泵无法输送的介质或离心泵无法适应的工况场合(图\文www.wxjpby.com/news.asp)。

Centrifugal pump with the advantages of simple structure, high efficiency, large flow, no pulse, low prices and widespread use of centrifugal pump, accounted for about all workers, more than eighty percent of the volume of agricultural pumps. Common features: simple structure smooth flow pulsation free medium and small flow field have similar efficiency and operation curve. Advantages: flexible pump centrifugal pump can only be used to thin, low viscosity of the liquid, to transportation, high viscosity fluid, semi-fluid. The flexible pump from low to high viscosity can be. Centrifugal pump with large transport of suspended particles in the medium. Centrifugal pump to transfer with gas liquid, foam liquid. Centrifugal pump with high speed, low speed operation can not, so the medium shear greatly, not suitable for the transport of shear sensitive media. Centrifugal pump Self-suction capability. If the self-priming need to add additional device, such as a liquid storage tank, valve, first start need irrigation fluid, completion of self-sucking action speed is slow; used in the health field, liquid storage tank has the potential to become the new source of pollution. In addition, centrifugal pump installation position is limited. Finally, note, centrifugal pump can not be used as a metering pump use. Generally speaking, the flexible pump and centrifugal pump without competitive relationship between. Flexible pump centrifugal pump pump as alternative, mainly used for suction centrifugal pump can transport medium or centrifugal pump can not adapt to situations.
