description	A peristaltic pump for conveying fluid in an apparatus for extracorporeal blood treatment includes a pump housing that accommodates a rotor. The rotor includes squeezing elements offset against each other in the circumferential direction. The pump housing includes a support surface extending in a curved shape around the rotor's axis. The support surface is radially spaced from the rotor and arranged to support a tube segment radially inserted between the rotor and the support surface. The rotor is driven by a rotor shaft, the rotary movement of which can be transmitted to a rotor base body via a freewheel press-fitted into a toothed driver sleeve. The freewheel has bearing positions for the rotor base body on both sides of the freewheel. To ensure coaxiality between the freewheel and the bearing support of the rotor base body, the bearing positions are defined by the geometry of the finished driver sleeve.
