Abstract (en)
[origin: WO8902538A1] A wheel for centrifugal pumps is composed of several metal sheet parts. In order to obtain a rigid construction, the energy transmitting blades are exclusively secured to the force-transmitting cover disk. The inlet area of the wheel forms a suction mouth formed as a single piece that covers the initial part of the blades and is secured thereto. A bladeless cover disk that covers the blade channels is secured to the blades between the outlet of the running wheel and the maximum diameter of the suction mouth.
