Pump with a conveyor device at least for conveying a fluid, and such a conveyor device

A pump for conveying a fluid, the pump comprising:

• conveyor device including a conveyor chamber, a dimensionally stable conveyor chamber element, an elastically deformable conveyor element, and a drive unit, the elastically deformable conveyor element delimits the conveyor chamber;
• the elastically deformable conveyor element together with the dimensionally stable conveyor chamber element delimits the dimensionally stable conveyor chamber and is arranged on the dimensionally stable conveyor chamber element, the drive unit configured to act on the conveyor device;
• and
• a housing for receiving the conveyor device, wherein the housing is formed separately from the conveyor device as a whole such that the conveyor device can be removed as a whole from the housing, wherein the dimensionally stable conveyor chamber element has an outer face which, in a state when the conveyor device is arranged on the housing, is connected in a force-fitting and/or form-fitting manner to an inner face of the housing, and rests against the inner face of the housing, wherein the conveyor chamber element, at least to a substantial extent, surrounds the elastically deformable conveyor element along a circumferential direction running in a plane extending at least substantially perpendicular to a drive axis of the drive unit.
