Abstract

The invention relates to the field of pump engineering and, more specifically, to impeller designs for centrifugal pumps. It can also be used in centrifugal ventilators and compressors. The aim of the invention is to reduce the turbulence of a flow of air or fluid in the channels between the blades of an impeller and thus increase the pressure and discharge rate, reduce vibration and, consequently, increase the efficiency of a pump. This aim is achieved by a pump, ventilator or compressor impeller which comprises a drive disc and a driven disc having main, peripheral and inner blades disposed therebetween and which is characterized in that each peripheral blade has a surface shape in the form of an arc of a circle and is connected along the line of the outside diameter of the impeller to the surface of a main blade on one side and to the surface of an inner blade on the other side so that the width of the radial channel formed by the adjacent (i.e. main and inner) blades is less at the outlet than the width of the radial channel at the inlet in inverse proportion to the change in flow velocity.
