Flexible pump and centrifugal pump comparison

Centrifugal pump due to simple structure, high efficiency, flow, pulsation, low price and widely used, accounting for all the workers, agricultural pumps more than 80 percent.
Common features:
Simple structure Smooth flow without pulse Small and medium flow areas have similar efficiency and operating curve Flexible pump advantages:
Centrifugal pump can only be used for thin, low viscosity liquid, can not transport medium and high viscosity fluid, semi-fluid. The flexible pump from low to high viscosity can be.
Centrifugal pumps can not transport medium with large suspended particles (small and medium flow areas).
Centrifugal pump can not transport gas-containing liquid, foam liquid.
Centrifugal pump speed, can not run at low speed, so the media cut great, not suitable for conveying shear sensitive media.
Centrifugal pump without self-suction capacity. If you want to self-priming need to add additional devices, such as the tank, bottom valve , the first start to be filled with liquid to complete the self-priming operation slow; used in the field of health, the tank may become a new source of pollution. In addition, the centrifugal pump installation location is limited.

Finally, please note that centrifugal pumps can not be used as metering pumps.

In general, there is no competition between the flexible pump and the centrifugal pump. Flexible pump as a centrifugal pump alternative pump, mainly used for suction and discharge centrifugal pump can not transport medium or centrifugal pump can not adapt to the occasion.
