The invention relates to an orbital pump for pumping a fluid, wherein the pump comprises at least one pump control system, a motor that can be controlled by the pump control system, a rotor shaft () for fluid transport, and a rotor sensor for detecting an absolute angle of rotation of the rotor shaft (), the rotor sensor is connected to the pump control system and designed to transmit the angle of rotation of the rotor shaft () to the pump control system, and the pump control system is designed to rotationally control the rotor shaft () by means of the motor until the rotor shaft () is in a pre-determined angle of rotation position.

Pump with detection of absolute angle of rotation

The invention relates to a pump device for pumping a liquid, comprising a hydraulics housing (), in which a pump ring (), a pump ring support () and an eccentric (), which can be driven by a shaft (), are accommodated. The hydraulics housing () has an annular portion () and a first and a second lateral section (), the two lateral sections () being arranged opposite each other. The pump ring () is mounted between the two lateral sections () of the hydraulics housing () at least in some portions. On a side facing away from the pump ring support (), two first projections (), which run in the axial direction of the shaft (), are each in contact with one of the two lateral sections ().

Pump device with deformable pump ring

The invention relates to a pump device for pumping a liquid having a hydraulics housing (), in which a pump ring (), a pump ring support (), and an eccentric () are accommodated, which eccentric is to be driven by a shaft (), which defines an axial and a radial direction, wherein the pump ring () has a first axial side () and a second axial side (), wherein the hydraulics housing () comprises an annular portion () and a first and a second lateral section (), wherein the two lateral sections () are arranged opposite each other, wherein the pump ring () is arranged, at least in some portions, between the two lateral sections () of the hydraulics housing (), and wherein on the first axial side () and the second axial side (), the profile of the pump ring () in each case follows a contour with an S-formed curve () with a convex section () and a concave section (), wherein the convex section () lies further outwards in a radial direction of the shaft () in comparison with the concave section ().

A pump device for pumping a liquid, has a hydraulics housing (), in which a pump ring () with a contact surface (), a pump ring support () and an eccentric (), which can be driven by a shaft (), are accommodated. The hydraulics housing () has an annular portion () and a first and a second lateral section (), the two lateral sections () being arranged opposite each other. The pump ring () is mounted between the two lateral sections () of the hydraulics housing () at least in some portions. The profile of the contact surface () has a contour with a curvature that changes at least in portions, and specifically in such a way that the curvature increases at least in some portions towards the ends of the contact surface ().
