    摘要: A rotor mounting on one end of a shaft, particularly a shaft end of a centrifugal pump unit, in which an adjusting surface and at least one contact surface are constructed on the shaft end, and in which a rotor hub is provided at least on the end facing the shaft with a central bore having an internal thread. The rotor hub is attached to the shaft end by a screw connection. The shaft has a central bore (16) having an internal thread (17) at least on the end facing the rotor hub (12); a threaded pin (18) constructed as a separate component is disposed in both central bores (13, 16) in a connecting, torque-transmitting and force-transmitting manner, and the rotor is aligned on the shaft solely by the adjusting surfaces (20) and contact surfaces (21).

    摘要: A centrifugal pump for conveying fluids with suspended solids has a single-blade impeller. The blade angle, as measured at the meridian line of the blade, is positive at the rear end of the blade and less than 0 degrees along a portion of the blade which extends from the front end towards the rear end of the blade through an angle of at least 90 degrees. The inner side of the blade defines a segment of a circle which is coextensive with this portion of the blade. The front end of the blade has a surface which bridges the inner and outer sides of the blade, and such surface is either flat or forms an arc having a radius of curvature substantially greater than half the blade thickness.
