ABSTRACT:
A pumping device for fluids, in particular for low-viscosity liquids such as washing suds or rinsing water, having a pump impeller whose flexible vanes rotate in an annular chamber, and a synchronous drive motor, the elasticity of the pump vanes being sufficient that the required accelerating moments during starting do not exceed the maximum torque produced by the motor, and the drive motor undergoes torsional vibrations during the starting phase.
