More Information
Summary:In many pump types, in particular in orbital pumps, there is an optimization need with regard to the running characteristics, in particular with regard to parameters which relate to the delivery flow. What is provided is an orbital pump device for delivering liquid medium by a rotational movement including a hydraulic housing surrounding a hydraulic chamber in a fluid-tight manner at least one membrane unit which is arranged inside the hydraulic chamber in flat contact with an inner jacket surface of the hydraulic housing; and an inlet and an outlet provided in the hydraulic housing. At least one crowning is provided at the inner jacket surface and/or at the membrane unit such that a radial gap between the membrane unit and the inner jacket surface is defined by the crowning in a circumferential section of less than 360°, and in particular less than 180°.
