The drive of ordinary centrifugal pump is through the coupling of the pump impeller shaft and electric shaft connected, so that the impeller and motor together with the rotation and work, and the shield pump is a non-sealed pump, both the pump and the drive motor are enclosed in a pressure vessel filled with a pumping medium, which is statically sealed, and a wire bank to provide a rotating magnetic field and drive the rotor. This structure cancels the traditional centrifugal pump with the rotating shaft seal device, so can be quiet and leak-free.
