Abstract
A system for manufacturing radionuclide generators includes an enclosure defining a radioactive environment. The enclosure includes radiation shielding to prevent radiation within the radioactive environment from moving to an exterior of the enclosure. The system also includes a pump within the enclosure for transferring fluid through tubing. The pump includes a pump head including a casing, a rotor that rotates in relation to the casing, and a clamp. The tubing extends through the pump head. The clamp compresses the tubing against the rotor and directs radioactive fluid through the tubing as the rotor rotates. The pump also includes a servomotor that controls the rotation of the rotor and a coupling connecting the pump head to the servomotor. The coupling prevents backlash between the servomotor and the rotor during rotation.
