Abstract
A pump for conveying a fluid includes a pump housing with an inlet, an outlet, an inner circumferential surface and a geometric axis. An eccentric is rotatable in the housing around the geometric axis. A deformable element is disposed in a pump gap between inner and outer surfaces of the eccentric. A conveying channel is formed from inlet to outlet by the deformable element and the inner circumferential surface. The deformable element is pressed in sections against the housing by the outer eccentric surface, forming a displaceable seal of the channel and a closed pump volume in the channel being displaceable by rotation of the eccentric for conveying the fluid along the channel from inlet to outlet. The deformable element has a protrusion on one or both sides towards the geometric axis extending over the outer eccentric surface and contacting the deformable element. A centering ring is inside the protrusion.
