Graphic-analytical method of defining pressure characteristics of centrifugal-vortex pumps

摘要

Centrifugal-vortex pumps are usually adopted for a small boiler feeding of audhot-water heating system and also in the water-supply system, in the food and oiludindustry.udCentrifugal-vortex pumps have rather good operating showings in theudresults of successful using of the positive qualities if the centrifugal working wheeludand vortex one. They are fixed on the common shaft.
