Abstract
A peristaltic pumping apparatus includes a pump rotor carrying a roller and a drive mechanism for rotating the rotor. The drive mechanism includes a carrier for holding the pump rotor. The apparatus includes a release pin mechanism carried on the pump rotor and exposed to access by a user. The release pin mechanism is movable by the user between a first position that connects the pump rotor to the carrier and a second position that disconnects the pump rotor from the carrier. Placing the release pin mechanism in the second position allows quick separation of the pump rotor from the drive mechanism.
