The invention relates to a pump for conveying a fluid, comprising a cylindrical housing and a pump shaft which is arranged in the interior of the cylindrical housing and which is rotatable about an axis, having an impeller which is arranged on the pump shaft in a torque-proof manner for acting on the fluid, the pump further has a pump inlet for supplying fluid to the interior space and a pump outlet for discharging fluid from the interior space, one end of the cylindrical housing is closed by a cover, and the pump comprises a clamping device for fixing the cover to the cylindrical housing, the clamping device comprising a clamping element and a clamping device which can be arranged in a bore of the clamping element, the clamping element includes first and second abutment surfaces. The clamping device is movably arranged relative to the clamping element along a clamping axis such that, in a mounted state of the cover, the clamping element is clamped between the cylindrical housing and the cover by cooperating with the clamping device, in which mounted state a clamping force is exerted on the cover by the cylindrical housing via the first abutment surface to the second abutment surface such that, in the mounted state, the clamping element is clamped between the cylindrical housing and the cover by cooperating with the clamping device. The cover is fixed to the cylindrical housing by a clamping force.
