A rotor for a peristaltic pump assembly which is formed of a unitary element having radial arms recessed at the distal ends to receive pressure rollers for the pump and wing formations at the distal ends for carrying guide rollers extending radially of the axis of the rotor and spaced axially on either side of the rollers to serve as a tube guide. The assembly includes a mount on the rotor for a drive crank which can be utilized in one position as a manual crank for the rotor and which can be stored within the rotor in a second position in which it also serves as a connection drive between a power shaft and the rotor. Movement of the crank to the manual position disconnects the rotor from the power drive.
