Abstract
A magnetic drive pump includes a magnetic coupling comprising an outer magnet rotor and an inner magnet rotor. The outer magnet rotor is driven by a separate motor. The outer magnet rotor is positioned radially outward of a sealing wall. The inner magnet rotor is positioned radially within the sealing wall, such that rotation of the inner magnet rotor causes the pump rotor to in turn rotate. The pump rotor drives a centrifugal pump impeller to move a liquid. A bubble detector is positioned outward of the wall such that it is in a dry side of the pump. The bubble detector sends a signal into a wet side of the pump to identify the existence of a gas within a pump fluid.
