The mechanical energy of the prime mover can be transferred to the liquid by the action of the rotating impeller to the liquid. Due to the centrifugal pump the liquid from the impeller inlet flow of exports, the velocity and pressure could have been increased by the impeller discharge liquid after extruding chamber. Most of the speed can be converted into pressure energy, then along the discharge pipe conveying out, at this time, at the inlet of the impeller for the expulsion of the liquid formed vacuum or pressure, ceiling in a pool of liquid in the liquid level pressure / high pressure under the action of, is pressed into the impeller inlet, so the rotating impeller continuous continuous inhalation and discharged liquid.
Single stage vertical centrifugal pump for vertical structure, import and export of the same caliber, and is located in the same center line, can be installed in the pipeline as the valve, compact and beautiful appearance, small occupation area, low construction investment.
