ABSTRACT:
A liquid pump, in particular for liquids having a low viscosity, for example, water, alcohols or other chemical liquids is provided of the type which includes a gear unit or a gerotor mounted in a housing which has an inner gear driven by a shaft. The inner gear of the gear unit is mounted on a bushing, the width of which is determined by the required hydrostatic support forces in such a manner that the support faces lie directly in the plane of the hydraulic radial forces.
