| A conveying device at least for conveying a fluid, includes at least one conveying space, with at least one conveying space element, which at least partly delimits the conveying space and is embodied in a rigid fashion, and with at least one elastically deformable conveying element, which forms the conveying space together with the conveying space element, at least the conveying space element and the conveying element together form an exchangeable unit. The conveying element is arranged on the conveying space element in an at least partly convexly curved fashion, following a deformation, the conveying element automatically seeks to re-assume a basic shape, and the conveying element is connected to the conveying space element in a non-releasable manner. | ||||||

| 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. | ||||||

| A pump for conveying a fluid includes a pump housing, an eccentric, a deformable element arranged in a pump gap between the inner circumferential surface of the pump housing, and an outer surface of the eccentric, such that a conveying channel is formed from an inlet to an outlet. A stationary seal is provided between the outlet and the inlet and prevents a backflow of the fluid from the outlet back to the inlet. The inner circumferential surface of the pump housing has a recess in the region of the stationary seal, and the deformable element is tensioned fluid-tight at the inner circumference surface in the region of the recess using a pin. | ||||||

| The invention relates to a pump device for pumping a liquid, comprising a hydraulics housing (12, 212), in which a pump ring (14, 214), a pump ring support (16, 216) and an eccentric (18), which can be driven by a shaft (20), are accommodated. The hydraulics housing (12, 212) has an annular portion (22, 222) and a first and a second lateral section (24, 26, 224), the two lateral sections (24, 26,224) being arranged opposite each other. The pump ring (14, 214) is mounted between the two lateral sections (24, 26, 224) of the hydraulics housing (12, 212) at least in some portions. On a side facing away from the pump ring support (16, 216), two first projections (28, 228), which run in the axial direction of the shaft (20), are each in contact with one of the two lateral sections (24, 26, 224). | ||||||

| The invention relates to a pump device (10) for pumping a fluid (13), comprising: a pump housing (12) having an annular portion (22); a pump ring (14), which is deformable and defines an annular pump chamber (57) at least in some portions; a first connection (51) and a second connection (52), said first connection (51) and said second connection (52) being in fluid communication with the pump chamber (57); an eccentric (18), which is designed to be rotatable relative to the pump housing (12) and which is arranged such in the pump device (10) that the eccentric (18), depending on a current rotational position of the eccentric (18), deforms the pump ring (14) in such a way that the pump ring (14) presses at least partially against the annular portion (22) in order to pump, by way of a rotation of the eccentric (18), the fluid (13) along the pump chamber (57) from the first connection (51) to the second connection (52) depending on the current rotational position of the eccentric; and a clamping element (114), which is designed to statically press the pump ring (14) against the annular portion (22) of the pump housing (12) in a clamping link region (45). The pump ring (14) has at least one recess (47) for accommodating at least part of the clamping element (114), said recess (47) being dimensioned such that in each rotational position of the eccentric (18) at least in some portions a distance (48) between the radially inner side (50) of the clamping element (114) and the pump ring (14) is provided. | ||||||

| The invention relates to a pump device for pumping a liquid, comprising a hydraulics housing (12), in which a pump ring (14) with a contact surface (46), a pump ring support (16) and an eccentric (18), which can be driven by a shaft (20), are accommodated, said shaft defining an axial and a radial direction. The hydraulics housing (12) has an annular portion (22) and a first and a second lateral section (24, 26), the two lateral sections (24, 26) being arranged opposite each other. The pump ring (14) is mounted between the two lateral sections (24, 26) of the hydraulics housing (12) at least in some portions. The profile of the contact surface (46) 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 (46). | ||||||

| A transfer pump. The pump is for displacing fluid and may generally include a housing; a pump including an impeller, the pump being disposed within the housing for creating suction to draw the fluid through the impeller; a motor for driving the pump; a battery operable to power the motor; and a sensor for sensing current drawn by the motor. The motor may be deactivated when the current drawn by the motor reaches a predetermined current value for a predetermined amount of time. | ||||||
